让我们假设我有这样的测试代码.
public class SimpleScheduler
{
public Script Script { get; set; }
private Thread _worker;
public void Schedule()
{
this._worker = new Thread(this.Script.Execute);
this._worker.Start();
}
public void Sleep()
{
//?
}
}
SimpleScheduler只需要获取Script对象并尝试在单独的线程中执行它.
public class Script
{
public string ID { get; set; }
private ScriptSource _scriptSource;
private ScriptScope _scope;
private CompiledCode _code;
private string source = @"import clr
clr.AddReference('Trampoline')
from Trampoline import PythonCallBack
def Start():
PythonCallBack.Sleep()";
public Script()
{
_scriptSource = IronPythonHelper.IronPythonEngine.CreateScriptSourceFromString(this.source);
_scope = IronPythonHelper.IronPythonEngine.CreateScope();
_code = _scriptSource.Compile();
}
public void Execute()
{
_code.Execute(_scope);
dynamic start = _scope.GetVariable("Start");
start();
}
}
Script类尝试回调PythonCallBack类的Sleep函数,并希望暂停一段时间.
public static class PythonCallBack
{
public static SimpleScheduler Scheduler;
static PythonCallBack()
{
Scheduler = new SimpleScheduler();
}
public static void Sleep()
{
Scheduler.Sleep();
}
}
PythonCallBack只是用于调用SimpleScheduler的sleep方法.
题:
暂停执行脚本的线程的最佳方法是什么?然后如何恢复此线程执行?
最佳答案 Thread类有一个Suspend()和Resume()方法.这些方法暂停并恢复线程.即使有关于此方法的警告,这也不应成为问题,因为您要暂停在已知位置.
另一种方法是使用事件.您可以为Script或ScriptScope类提供AutoResetEvent.然后,在Sleep()中,在事件上调用WaitOne().然后,从外部,当您希望线程恢复时,您调用Set().
