C# 如何在不暂停GUI的情况下在计时器内运行不同的计时器?
我有一个SendCountingInfo()类,它将每5分钟向服务器发送一条消息。此类中的代码是:C# 如何在不暂停GUI的情况下在计时器内运行不同的计时器?,c#,timer,C#,Timer,我有一个SendCountingInfo()类,它将每5分钟向服务器发送一条消息。此类中的代码是: public void StartSendCountingInfo() { DoStartSendCountingInfo(300000); } private void DoStartSendCountingInfo(int iMiSecs) { _pingTimer = new System.Timers.Timer(iMiSecs); _pingTime
public void StartSendCountingInfo()
{
DoStartSendCountingInfo(300000);
}
private void DoStartSendCountingInfo(int iMiSecs)
{
_pingTimer = new System.Timers.Timer(iMiSecs);
_pingTimer.Elapsed += new System.Timers.ElapsedEventHandler(pingTimer_Elapsed);
_pingTimer.Start();
}
void pingTimer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
PingRemoteHost();
}
当我试图在Windows窗体类中调用它时,它不起作用。
但是,当我删除计时器并直接调用PingRemoteHost()时,它就工作了。但是,表单没有正确加载。它显示空白屏幕,但PingRemoteHost()方法有效
以下是windows窗体中的代码:
private void Layout_Load(object sender, EventArgs e)
{
tSystemChecker = new System.Timers.Timer(1000);
tSystemChecker.Elapsed += new System.Timers.ElapsedEventHandler(tSystemChecker_Elapsed);
tSystemChecker.Start();
this.WindowState = FormWindowState.Maximized;
}
void tSystemChecker_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
UIThreadWork(this, delegate
{
try
{
SuspendLayout();
DoCheckHardwareStatus();
DoCheckLanguage();
SendCountingInfo sci = new SendCountingInfo();
sci.StartSendCountingInfo();
}
catch (Exception exp)
{
System.Diagnostics.Debug.WriteLine(exp.Message);
System.Diagnostics.Debug.WriteLine(exp.Source);
System.Diagnostics.Debug.WriteLine(exp.StackTrace);
}
ResumeLayout(true);
});
}
你知道出了什么问题吗?使用一个线程,看看问题是否仍然存在
using System.Threading;
//Put this where you want to start the first timer
Thread thread = new Thread(dowork =>
{
public void StartSendCountingInfo();
}
如果要更新GUI,请使用控件
guicontrol.BeginInvoke((MethodInvoker)delegate()
{
guicontrol.Text = "aa";
//etc
});
