、添加命名空间：
using System.Runtime.InteropServices; 、定义常量值及函数：
private const int CS_DropSHADOW = 0x20000;
private const int GCL_STYLE = (-);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern int SetClassLong(IntPtr hwnd, int nIndex, int dwNewLong);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern int GetClassLong(IntPtr hwnd, int nIndex); 、构造方法下引用：
SetClassLong(this.Handle, GCL_STYLE, GetClassLong(this.Handle, GCL_STYLE) | CS_DropSHADOW);
控制窗口关闭
this.Close(); // 窗口关闭
控制窗口最小化
