1.创建类，继承接口IWin32Window

public class WindowWrapper : System.Windows.Forms.IWin32Window
{
        private System.IntPtr _hwnd;
        public WindowWrapper(System.IntPtr handle)
        {
            _hwnd = handle;
        }
        public System.IntPtr Handle
        {
            get { return _hwnd; }
        }
} 

2.然后封装系统获取主窗体API

[System. Runtime. InteropServices. DllImport ( "user32")]
public static extern System. IntPtr GetForegroundWindow(); 

System.IntPtr IntPart;
IntPart = GetForegroundWindow();
WindowWrapper ParentFrm = new WindowWrapper(IntPart);
MessageBox.Show(ParentFrm, "测试OK!", "提示", MessageBoxButtons.OK,MessageBoxIcon.Information);
