Winform下去除MDI表單邊框

做項目中間遇到了MDI表單內邊框的問題，經過苦苦尋找，最終得到瞭解決方案

在Main表單中調用API

  // Win32 Constants            private const int GWL_STYLE = -16;        private const int GWL_EXSTYLE = -20;        private const int WS_BORDER = 0x00800000;        private const int WS_EX_CLIENTEDGE = 0x00000200;        private const uint SWP_NOSIZE = 0x0001;        private const uint SWP_NOMOVE = 0x0002;        private const uint SWP_NOZORDER = 0x0004;        private const uint SWP_NOACTIVATE = 0x0010;        private const uint SWP_FRAMECHANGED = 0x0020;        private const uint SWP_NOOWNERZORDER = 0x0200;        // Win32 方法            [DllImport("user32.dll", CharSet = CharSet.Auto)]        private static extern int GetWindowLong(IntPtr hWnd, int Index);        [DllImport("user32.dll", CharSet = CharSet.Auto)]        private static extern int SetWindowLong(IntPtr hWnd, int Index, int Value);        [DllImport("user32.dll", ExactSpelling = true)]        private static extern int SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter,            int X, int Y, int cx, int cy, uint uFlags);


擷取到API後在Form_Load事件中加入如下代碼  

  //擷取mdi客戶區                for (int i = 0; i < this.Controls.Count; i++)            {                var mdiClientForm = this.Controls[i] as MdiClient;                if (mdiClientForm == null) continue;                // 找到了mdi客戶區                    // 取得客戶區的邊框                    int style = GetWindowLong(mdiClientForm.Handle, GWL_STYLE);                int exStyle = GetWindowLong(mdiClientForm.Handle, GWL_EXSTYLE);                style &= ~WS_BORDER;                exStyle &= ~WS_EX_CLIENTEDGE;                // 調用win32設定樣式                    SetWindowLong(mdiClientForm.Handle, GWL_STYLE, style);                SetWindowLong(mdiClientForm.Handle, GWL_EXSTYLE, exStyle);                // 更新客戶區                    SetWindowPos(mdiClientForm.Handle, IntPtr.Zero, 0, 0, 0, 0,                    SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER |                    SWP_NOOWNERZORDER | SWP_FRAMECHANGED);                UpdateStyles();                break;            }

重新運行程式，OK
