private void BtnStopAutoUpd_Click(object sender, EventArgs e)
{
autoReadThread.Suspend();
}
private void BtnStartAutoUpd_Click(object sender, EventArgs e)
{
autoReadThread.Resume();
}
但我正面临这个警告,
Thread.Suspend已被弃用。请使用System.Threading中的其他类(如Monitor,Mutex,Event和Semaphore)来同步线程或保护资源。 http://go.microsoft.com/fwlink/?linkid=14202
我怎么只运行单线程(而不是GUI线程),所以如何在这里应用同步或监控。
更新代码:
class ThreadClass
{
// This delegate enables asynchronous calls for setting the text property on a richTextBox control.
delegate void UpdateTextCallback(object text);
// create thread that perform actual task
public Thread autoReadThread = null;
public ManualResetEvent _event = new ManualResetEvent(true);
// a new reference to rich text box
System.Windows.Forms.RichTextBox Textbox = null;
private volatile bool _run;
public bool Run
{
get { return _run; }
set { _run = value; }
}
public ThreadClass(string name, System.Windows.Forms.RichTextBox r1)
{
Textbox = r1;
Run = true;
this.autoReadThread = new Thread(new ParameterizedThreadStart(UpdateText));
this.autoReadThread.Start(name);
}
private void UpdateText(object fileName)
{
//while (true)
//{
// _event.WaitOne();
while (Run)
{
if (Textbox.InvokeRequired)
{
UpdateTextCallback back = new UpdateTextCallback(UpdateText);
Textbox.BeginInvoke(back, new object[] { fileName });
Thread.Sleep(1000);
}
else
{
string fileToUpdate = (string)fileName;
using (StreamReader readerStream = new StreamReader(fileToUpdate))
{
Textbox.Text = readerStream.ReadToEnd();
}
break;
//}
}
}
}
}
}
run是bool值,一个线程控制它(最初是真的)
并启动线程我在其他类中创建此类实例(此启动线程)
