想了解C#定时关闭窗体实例的相关内容吗，在本文为您仔细讲解C#定时关闭窗体的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：C#,定时,关闭,窗体，下面大家一起来学习吧。

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);

复制代码代码如下:

<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");  

        }  

    }

希望本文所述对大家的C#程序设计有所帮助。
