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：
复制代码 代码如下: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> <span>[DllImport("user32.dll",SetLastError=true)]</span><br><span> 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。
