這篇文章主要介紹了C#定時(shí)關(guān)閉窗體實(shí)例,在Windows桌面應(yīng)用程序開發(fā)中具有一定的實(shí)用價(jià)值,需要的朋友可以參考下

本文實(shí)例講述了C#定時(shí)關(guān)閉窗體的方法，分享給大家供大家參考。具體方法如下：

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);

復(fù)制代碼代碼如下:

<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");  

        }  

    }

希望本文所述對(duì)大家的C#程序設(shè)計(jì)有所幫助。
