C#SetWindowPos窗口置顶
2014-08-29来源:

[DllImport("user32.dll", CharSet = CharSet.Auto)]

private static extern int SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int y, int Width, int Height, int flags);

/// <summary>

/// 得到当前活动的窗口

/// </summary>

/// <returns></returns>

[DllImport("user32.dll", CharSet = CharSet.Auto)]

private static extern System.IntPtr GetForegroundWindow();

哪个窗体想要置顶,在Form_Load中加上

SetWindowPos(this.Handle, -1, 0, 0, 0, 0, 1 | 2); //最后参数也有用1 | 4 

具体说明,看API函数说明

如果是用点击一个按钮后弹出新窗体,并置顶,则:

Form2 frm = new Form2();

frm.Show();

SetWindowPos(GetForegroundWindow(), -1, 0, 0, 0, 0, 1 | 2);
