C#定时关闭窗体实例

本文实例讲述了C#定时关闭窗体的方法，分享给大家供大家参考。具体方法如下：

public partial class Form2 : Form  

{  

private System.Timers.Timer timer = new System.Timers.Timer(); 

public Form2()  

{  

    InitializeComponent();  

    InitStatus();  

    timer.Interval = 4000;  

    timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);  

    timer.Enabled = true;  

} 
void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)  

{  

    IntPtr hDlog = FindWindow(null, "Show");  

    if (IntPtr.Zero != hDlog)  

    {   

 IntPtr result;  

 EndDialog(hDlog, out result);  

    }  

} 
private void InitStatus()  

{  

    this.panel1.Controls.Clear(); 
    Form1 from1 = new Form1();  

    from1.TopLevel = false;  

    from1.FormBorderStyle = FormBorderStyle.None; 
    this.panel1.Controls.Add(from1);  

    from1.Show();  

}  

[DllImport("user32.dll",SetLastError=true)]  

public static extern IntPtr FindWindow(string lpClassName, string caption);

<span style="white-space:pre">  <span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240); ">[DllImport("user32.dll",SetLastError=true)]</span><br style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240); "><span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240); ">        public static extern int PostMessage(IntPtr hWnd, int message, IntPtr wParam, IntPtr lParam);</span>  

</span>  

  

  

        [DllImport("user32.dll",SetLastError=true)]  

        public static extern bool EndDialog(IntPtr hDlg, out IntPtr nResult);  

  

        private void button1_Click(object sender, EventArgs e)  

        {  

            MessageBox.Show("corning", "Show");  

        }  

    }
