创建快捷方式

参考：https://stackoverflow.com/questions/4897655/create-a-shortcut-on-desktop

1.不带COM库引用方法（方法内部引用，不需要在程序手动添加引用）

using System.Text;
using System.Linq;
using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using System.Runtime.InteropServices.ComTypes;
static void Main(string[] args)
{
    IShellLink link = (IShellLink)new ShellLink();
    link.SetPath(@"D:\test\gif\GifCam.exe");//目标
    link.SetArguments(" -run 1");//启动参数
    link.SetWorkingDirectory(@"D:\test\gif");//起始位置
    link.SetHotkey((short)((short)Hotkey.Ctrl | (short)Hotkey.Alt | (short)'1'));//快捷键
    link.SetShowCmd((int)CmdShow.Maximized);//显示窗口方式
    link.SetDescription("Gif录制");//描述
    link.SetIconLocation(@"D:\test\gif\GifCam.exe", 0);//设置图标
    IPersistFile file = (IPersistFile)link;
    string path = @"D:\test\gif\GifCam.lnk";//快捷方式位置
    file.Save(path, false);
}

2.带COM库
需要添加 COM引用 Windows Script Host Object Model

using IWshRuntimeLibrary;
static void Main(string[] args)
{
    IWshShortcut shortcut = (IWshShortcut)new WshShell().CreateShortcut(@"D:\test\gif\GifCam.lnk");//创建快捷方式对象
    shortcut.TargetPath = @"D:\test\gif\GifCam.exe";//指定目标路径
    shortcut.WorkingDirectory = @"D:\test\gif";//设置起始位置
    shortcut.WindowStyle = 1;//设置窗口显示方式，1=常规窗口,2=最小化(无效),3=最大化
    shortcut.Description = "Gif录制2";//设置备注
    shortcut.Hotkey = "Ctrl+Alt+Left";//设置快捷键
    shortcut.IconLocation = @"D:\test\gif\GifCam.exe,0";//设置图标
    shortcut.Arguments = " -run 3";//启动参数
    shortcut.Save();//保存快捷方式
}
