How to make a method run in the "background" (threading?)
提问by James
I currently have some code that cycles through a text file looking for a specific phrase. However, when this method runs, the whole application locks up. I assume because it's looping, which is what I want.
我目前有一些代码可以在文本文件中循环查找特定短语。但是，当此方法运行时，整个应用程序都会锁定。我假设因为它是循环的，这就是我想要的。
I would like this to happen in the background, so normal methods and user interaction with the application can still be done.
我希望这在后台发生，因此仍然可以完成正常的方法和用户与应用程序的交互。
How can this be done/improved?

private void CheckLog()
{
while (true)
{
// lets get a break
Thread.Sleep(5000);
if (!File.Exists("Command.bat"))
{
continue;
}
using (StreamReader sr = File.OpenText("Command.bat"))
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
if (s.Contains("mp4:production/"))
{
// output it
MessageBox.Show(s);
}
}
}
}
}

Use
用
class Foo {
private Thread thread;
private void CheckLog() {...}
private void StartObserving() {
thread = new Thread(this.CheckLog);
thread.Start();
}
}
or the backgroundworker component from the palette.
或调色板中的后台工作组件。
