private const int WM_SETREDRAW = 0xB;
private void Form1_MouseDown(object sender, MouseEventArgs e)

if (this.WindowState == FormWindowState.Normal)

ReleaseCapture();
SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
}
}
//窗體陰影API
1、添加命名空間： using System.Runtime.InteropServices; 2、定義常量值及函數： private const int CS_DropSHADOW = 0x20000; private const int GCL_STYLE = (-26); [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); 3、構造方法下引用： SetClassLong(this.Handle, GCL_STYLE, GetClassLong(this.Handle, GCL_STYLE) | CS_DropSHADOW);
