界面设计简述
引言
在我们掌握了交互式工具的使用方法后，在使用过程中会发现：虽然工具中拥有多种交互的手段，但仅凭工具中鼠标，特殊按键与信息提示等交互方法，没有办法同时对多个信息进行展示，也不够直观。而界面不仅可以自定义展示内容，同时也可根据用户的行为实现数据交换，因此掌握界面的制作方法便显得十分重要。基于系列直播课程开办的初衷，凭借上手难度低，学习资料丰富的优势，本次与大家分享的是Winform界面创建及常用控件的使用方法。
WinForm概念简述
WinForm是 Windows Form 的简称，是基于 .NET Framework 平台的客户端（PC软件）开发技术，一般使用 C# 编程。WinForm 编程需要创建「Windows窗体应用程序」项目。Windows 窗体应用程序是 C# 语言中的一个重要应用，也是 C# 语言最常见的应用。使用 C# 语言编写的 Windows 应用程序与 Windows 操作系统的界面类似，每个界面都是由窗体构成的，并且能通过鼠标单击、键盘输入等操作完成相应的功能。其具有以下优势：<br />1.用户体验好，上手简单，界面反应速度快<br />2.单机版程序，适合数据敏感使用场景<br />3.开发便利，无需部署云端，.NET 提供了大量 Windows 风格的控件和事件
WinForm和WPF
提到WinForm就无可避免的会提到WPF，二者都是为了创建桌面客户端应用程序的 UI 框架。<br /> WinForm可用于设计窗体和可视控件，以创建丰富的基于Windows的应用程序。Windows窗体提供了一套丰富的控件，并且开发人员可以定义自己有特色的新的控件。它的设计器是使用Visual Studio自带的控件进行拖拽，设置控件对应的属性，事件。<br /> WPF能做到分离界面设计人员与开发人员的工作，提供多媒体交互用户图形界面。它的设计器是用xaml语言来写的，就像写html一样。<br />对于二者的区别，主要有以下几点：
- WinForm是“前后端”不分离的，WPF是前后端分离的。WinForm的设计器和CS文件的编码“耦合度”太高了，不能独立进行设计页面
- WPF的UI更加华丽，扩展性较高，但前提是需要会写样式，同时内存占用较高
- WPF 可以实现数据类似vue=>data绑定，WinForm没有这种方式，控件值需要内部赋值才能起到与WPF相同的效果
- WPF支持控件自适应
- Winform上手难度低，WPF的制作需要学习xaml语法，布局方面难度较大
WinForm界面开发方法
创建WinForm应用
首先需要明确的是：WinForm界面开发作为通用的界面设计开发方式，使用范围不仅局限于MicroStation二次开发，还可使用到其他的程序中，因此，若您希望获得更多WinForm的开发技巧，可以在网上获取更多的相关资料。<br /> 对于MicroStation二次开发来说，我们首先需要在工程中创建一个新的项目，具体方式右键工程调出菜单，点击添加后直接选择创建WimForm界面或点击新项目调出文件创建菜单。<br /><br />**图1 工程菜单界面**<br /> 若采用第一种方式创建WinForm菜单，需要选择菜单界面中的WindowForm选项，同时可在下方对该文件进行命名，完成后点击添加。<br /><br />**图2 添加项目界面**
WinForm界面设计
添加完成之后会生成一个WinForm界面，此时我们可以选择左边的Toolbox，其中提供了很多控件，方便应对不同的交互需求。
图3 WinForm界面
图4 Toolbox界面
当我们需要使用控件时，只需要从工具箱中拉取对应的控件到界面中，使用拖拽或者调整控件中属性的方法对控件尺寸进行调整，此时最简单的界面就已经布置完成。这里我们使用Button控件来进行演示，可以看到，从工具箱中拖拽出来后，可以使用鼠标拖拽或属性值修改的方式来实现界面的设计。
图5 WinForm界面设计
对于WinForm界面的设计来说，控制界面行为的有属性与事件，属性指的是状态，比如说Button中的属性有按钮的名称，大小，位置，颜色等等，而事件有点像参数化工具中的事件，当我们做出指定行为时若注册了事件那么就会触发该事件。属性和行为的修改不仅可以通过界面，也可通过代码来实现。其实界面生成与代码本质上是一致的，只不过在界面上的操作会自动生成对应的属性设置或者注册对应的事件，更加方便与高效。

图7 代码修改属性
图8 界面设置事件
public Form1(){InitializeComponent();button1.Text = "确认";button1.AutoSizeChanged += Button1_AutoSizeChanged;}private void Button1_AutoSizeChanged(object sender, EventArgs e){}
WinForm常用控件及使用方法介绍
正如上文所述，WinForm使用属性与事件实现数据与用户的信息传递。对于MicroStation二次开发而言，界面的控件主要用于用户信息与MicroStation软件中数据的交换。常用的控件有Button，CheckBox，ComboBox，Label，ListBox，Panel，ProgressBar，RadioButton，TextBox，TreeView等，在这里我们对常用控件的使用方法进行简单介绍。<br /><br />**图9 WinForm常用控件**
WinForm界面
对于WinForm界面来说，若需要对界面进行定制，我们便需要修改其属性，较为常用的是修改WinForm标题栏中的文字大小，字体，或者对界面图表进行设置，包括是否启动最大化，最小化按钮等。
修改界面图标
当我们需要修改界面图标时，需要点击Icon，导入指定的后缀为.ico的文件，此时便会替换为指定图标文件。
图10 WinForm界面属性面板
锁定/解锁最大/小化按钮
当我们需要锁定或者解锁最大或最小化按钮，此时需要对最大化/最小化窗口进行设置。<br /><br />**图11 WinForm界面属性面板**
修改界面标题文字
当我们需要修改标题的文字时，可以在属性名为Text处进行修改。<br /><br />**图12 WinForm界面属性面板**
Button控件
Button控件即按钮，一般用于提供给用户进行确认信息无误后执行的操作。<br /><br />**图13 Button控件**
常用事件
常用的事件主要为**点击按钮**触发事件。双击Click后的空白处或直接双击界面上的该控件后会自动生成代码注册该事件，并跳转到触发该事件后执行的方法，在方法中补充对应的业务函数。<br /><br />**图14 Button控件属性面板**<br /><br />**图15 代码中自动添加的事件**
private void button1_Click_1(object sender, EventArgs e){}
CheckBox控件
复选框主要用于选择单个/多个条件时的条件选择。<br /><br />**图16 CheckBox控件**
常用事件
常用的事件主要为在用户**点击复选框**时选择状态的更改触发事件。双击CheckedChanged后的空白处或直接双击界面上的该控件后会自动生成代码注册该事件，并跳转到触发该事件后执行的方法，在方法中补充对应的业务函数。<br /><br />**图17 CheckBox控件属性面板**<br /><br />**图18 代码中自动添加的事件**
private void checkBox1_CheckedChanged(object sender, EventArgs e){}
常用属性
我们通过复选框的属性**查看或者修改选择状态**，以便达到获取用户交互信息的目的，方法为获取或者修改该复选框的Checked属性，若为true则为选中状态，反之则反。<br /><br />**图19 复选框的选中属性**
ComboBox控件
下拉框用于多种选项的单项选择，它使用滚动的方式呈现出可供选择的所有项目。<br /><br />**图20 ComboBox控件**
常用事件
当我们**点击下拉框**时，可能需要动态的对下拉框中的内容进行补充。双击DropDown后的空白处会自动生成代码注册该事件，并跳转到触发该事件后执行的方法，在方法中补充对应的业务函数。<br /><br />**图21 ComboBox控件属性面板**<br /><br />**图22 代码中自动添加的事件**
private void comboBox1_DropDown(object sender, EventArgs e){}
当我们在下拉框中**选定指定项**时，可能需要针对选定的项执行一系列的操作。双击SelectedIndexChanged后的空白处或直接双击界面上的控件后会自动生成代码注册该事件，并跳转到触发该事件后执行的方法，在方法中补充对应的业务函数。<br /><br />**图23 ComboBox控件属性面板**<br /><br />**图24 代码中自动添加的事件**
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e){}
常用属性
当我们需要查看或者对下拉框添加项目的话，一方面我们可以通过下拉框中的Items属性进行项目的添加，另一方面我们可以使用代码执行下拉框项目的添加，修改与删除。<br /><br />**图25 ComboBox控件属性面板**
comboBox1.Items.Add("obj");//添加comboBox1.Items.Remove("obj");//删除comboBox1.Items.Clear();//清空列表bool isExist= comboBox1.Items.Contains("obj");//查询
Label控件
标签主要用于信息示意，给用户输入或输出提供帮助。<br /><br />**图26 Label控件**
常用属性
最常用的即为修改Label控件的文字表示了，我们可以通过Label控件界面的Text属性进行修改，或者使用代码执行文字修改。<br /><br />**图27 Label控件属性面板**
label1.Text = "test";//赋值
ListBox控件
ListBox主要用于需要单选/多选项目，相比于ComboBox，他会将待选项全部呈现在列表中，并可进行多项选择。<br /><br />**图28 ListBox控件**
常用事件
当我们在ListBox中的选取项目修改时，可能需要执行对应的业务函数，此时就需要引入索引修改的事件。双击SelectedIndexChanged后的空白处或直接双击界面上的控件后会自动生成代码注册该事件，并跳转到触发该事件后执行的方法，在方法中补充对应的业务函数。<br /><br />**图29 ListBox控件属性面板**<br /><br />**图30 代码中自动添加的事件**
private void listBox1_SelectedIndexChanged(object sender, EventArgs e){}
常用属性
当我们需要查看或者对下拉框添加项目的话，一方面我们可以通过下拉框中的Items属性进行项目的添加，另一方面我们可以使用代码执行下拉框项目的添加，修改与删除。<br /><br />**图31 ListBox控件属性面板**
listBox1.Items.Add("obj");//添加listBox1.Items.Remove("obj");//删除listBox1.Items.Clear();//清空列表bool isExist = listBox1.Items.Contains("obj");//查询
在ListBox中选择子项时，可以使用属性中的SelectionMode进行切换，分为：
- SelectionMode.None：不允许选中
- SelectionMode.One：只允许用户选择一项
- SelectionMode.MultiExtended：允许选择多项，但选中的条目必须相邻
- SelectionMode.MultiSimple：允许选择多项，可任意选中多个条目
Panel控件
Panel是一个包含其他控件的控件。 可以使用 Panel 来组合控件的集合，例如一组 RadioButton 控件。 与其他容器控件（如 GroupBox 控件）一样，如果 Panel 控件的 Enabled 属性设置为 false，则也会禁用包含在Panel中的控件。<br /><br />**图33 Panel控件**
m_previewPanel = new PreviewPanel(m_dgnModel);//初始化用户控制m_previewPanel.Dock = DockStyle.Fill;//设置模式为填充panel_view.Controls.Add(m_previewPanel);//将用户控制添加到面板中
例如下图，用于预览构件尺寸的UserControl被添加到Panel中。<br /><br />**图34 添加用户控件的Panel**
ProgressBar控件
ProgressBar控件主要用于显示进度状态，当我们执行操作需要一定时间时，为了实时显示进度状态，就可添加该控件。使用该控件时需要设置进度条的最小值与最大值，当前进度条的值与步长，比如在下面这个例子中，进度条是为了实时显示复制状态。<br /><br />**图35 ProgressBar控件**
#region ProgressBarm_progressBar_copyprogress.Minimum = 1;//设置进度条的最小值m_progressBar_copyprogress.Maximum = 100;//设置进度条的最大值m_progressBar_copyprogress.Value = 1;//设置进度条的值m_progressBar_copyprogress.Step = 100 / m_selectedElems.Count;//设置进度条的步长#endregionfor (int i=0;i<m_selectedElems.Count;i++)//遍历元素容器中的元素{using (ElementCopyContext copyContext = new ElementCopyContext(m_dgnModel))//复制元素{m_progressBar_copyprogress.PerformStep();//进度条按照步长推进copyContext.DoCopy(m_selectedElems[i]);//复制元素到当前的模型空间中}}m_progressBar_copyprogress.Value = 100;//设置进度条的值
RadioButton控件
RadioButton控件主要用于单项选择，即在指定范围内的所有RadioButton控件只能有一个处于选中状态。<br /><br />**图36 RadioButton控件**
常用事件
常用的事件主要为在用户**点击单选按钮**时选择状态的更改触发事件。双击CheckedChanged后的空白处或直接双击界面上的该控件后会自动生成代码注册该事件，并跳转到触发该事件后执行的方法，在方法中补充对应的业务函数。<br /><br />**图37 RadioButton控件属性面板 **<br /><br />**图38 代码中自动添加的事件**
private void radioButton1_CheckedChanged(object sender, EventArgs e){}
常用属性
当我们需要设置RadioButton的选中状态时，可以使用RadioButton中的Checked属性。 我们通过单选选项的属性**查看或者修改选择状态**，以便达到获取用户交互信息的目的，方法为获取或者修改该复选框的Checked属性，若为true则为选中状态，反之则反。<br /><br />**图39 RadioButton控件属性面板 **<br /><br />**图40 RadioButton的选中属性**
TextBox控件
常用事件
当我们需要**控制文本框的输入内容**时，比如限制文本框仅可输入中文，或者数字等，就需要添加KeyPress事件。双击KeyPress后的空白处会自动生成代码注册该事件，并跳转到触发该事件后执行的方法，在方法中补充对应的业务函数。<br /><br />**图41 TextBox控件属性面板 **<br /><br />**图42 代码中自动添加的事件**<br /> 例如在本案例中，就添加了一个只允许在文本框中输入数字的机制。
private void textBox1_KeyPress(object sender, KeyPressEventArgs e){if (e.KeyChar != 8 && !Char.IsDigit(e.KeyChar))//只允许输入数字与删除键{e.Handled = true;//返回成功}}
当我们需要在**文本框中的文字修改**后执行相应操作时，可以添加TextChanged事件。双击TextChanged后的空白处或直接双击界面上的该控件后会自动生成代码注册该事件，并跳转到触发该事件后执行的方法，在方法中补充对应的业务函数。<br /><br />**图43 TextBox控件属性面板 **<br /><br />**图44 代码中自动添加的事件**
private void textBox1_TextChanged(object sender, EventArgs e){}
常用属性
当我们不允许用户输入，只将TextBox作为一个输出信息的载体时，可将Enabled设置为false。<br /><br />**图44 TextBox控件属性面板**<br /> 当我们需要在TextBox控件中设置文字时，可在Text属性处直接添加文字，同时也可使用代码进行设置。<br /><br />**图45 TextBox控件属性面板**
textBox1.Text = "Test";//设置文本框中文字信息
TreeView控件
常用事件
当我们选择了指定树状图节点时，可能需要执行一些业务函数，此时需要添加NodeMouseClick事件。双击NodeMouseClick后的空白处会自动生成代码注册该事件，并跳转到触发该事件后执行的方法，在方法中补充对应的业务函数。<br /><br />**图47 TreeView控件属性面板**<br /><br />**图48 代码中自动添加的事件**
private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)//点击树状图节点时触发{AddECPropItems(e);//在用户控件界面添加EC属性框}
常用属性
当我们需要向树状图时，总是无可避免的涉及到节点的添加，删除以及嵌套，此时需要使用Nodes属性，若需要在节点上添加分支，则需要使用TreeNode类。
treeView1.Nodes.Add("test");TreeNode node1 = new TreeNode("n1");treeView1.Nodes.Remove(node1);TreeNode node2 = new TreeNode("n2");treeView1.Nodes.Add(node2);TreeNode node3 = new TreeNode("n3");node2.Nodes.Add(node3);TreeNode node4 = new TreeNode("testNode");treeView1.Nodes.Add(node4);
案例实战
为了展现在MicroStation二次开发中使用WinForm界面控件与MicroStation内的数据交互，这里我们使用三个案例进行展示，分别为可视化矩形梁生成工具，EC属性赋值工具与文件选择复制工具。<br />
可视化矩形梁生成工具
该工具会根据用户输入的数据实时在Panel中的用户控件中对截面信息进行预览，确定截面信息无误后点击确认会启动交互式工具，根据用户输入的信息生成矩形梁截面，通过交互式工具用户点击的位置确认矩形梁的起点与终点。<br /> 该工具涉及到的WinForm控件有：Label，TextBox，Button，Panel，UserControl（用户自定义控件）。<br /><br />**图50 工具流程图**<br /><br />**图51 控件调用流程图**

文件选择复制工具
该工具会根据用户选择获得需要赋值元素的文件，读取文件信息后根据用户选择的模型动态读取模型中的元素信息，并实时调整条件筛选多选框中元素类型，元素图层，ItemType信息等，同时根据多选框中的设置动态锁定/解锁下拉框，用机制保证就算用户没有使用该工具的经验，只要根据插件给出的信息即可直接上手。最后点击执行后，程序会根据当前的筛选条件动态赋值模型中的元素，同时当RadioButton选中的是输出生成信息时，输出复制结果。并且在复制过程中，使用ProgressBar显示复制进程。<br /> 该工具涉及到的WinForm控件有：TextBox，Button，ComboBox，ListBox，RadioButton，Label，CheckBox，ProgressBar。<br /><br />**图56 工具流程图**<br /><br />**图57 控件调用流程图**

注意事项
- 在MicroStation二次开发的环境下使用WinForm时，需要将继承的Form修改为Bentley.MstnPlatformNET.WinForms.Adapter
- 在MicroStation中需要调用界面时，需要首先对界面进行声明，然后使用模态显示（ShowDialog）和非模态显示（Show），模态与非模态窗体的主要区别是窗体显示的时候是否可以操作其他窗体。模态窗体不允许操作其他窗体，非模态窗体可以操作其他窗体。
BeamCreateMenu menu = new BeamCreateMenu();//声明界面menu.Show();//展示界面
