基本操作符

    • new
      • 操作符
      • 修饰符

    • check & uncheck

      1. try
      2.           {   int x = int.MaxValue;
      3.               int y = checked(x+1);
      4.           }
      5.           catch (OverflowException ex)
      6.           {
      8.               Console.WriteLine("There's overflow!");
      9.           }

    • delegate

      • 匿名方法（已经过时了）
        1.  this.button1.Click += delegate(object sender, RoutedEventArgs e)
        2.    {
        3.        this.textBox1.Text = "Hello world!";
        4.    };

    • lambda

      • 符号：=>
        1. this.button1.Click += ( sender,  e) =>
        2.    {
        3.        this.textBox1.Text = "Hello world!";
        4.    };

    • sizeof

    **

    • “ -> “
      • 像指针操作、取地址操作，以指针访问操作 只能操作结构体，不能操作引用类型
