C# - ThreadPool QueueUserWorkItem 使用?

问题描述

现在我正在使用以下代码添加排队线程.我不喜欢它.我的同事也不会，因为他们不太了解 C#.当然，我想要的只是将要在新线程中执行的方法排队.

Just right now I'm using following code to add queued threads. I don't like it. And my colleagues won't either because they don't know C# very well. All I want is of course to queue a method to be executed in a new thread.

private static void doStuff(string parameter)
{
    // does stuff
}

// call (a)
ThreadPool.QueueUserWorkItem(a => doStuff("hello world"));
// call (b)
ThreadPool.QueueUserWorkItem(delegate { doStuff("hello world"); });

那么 ThreadPool.QueueUserWorkItem 还有其他使用变体吗?

So are there other use variations of ThreadPool.QueueUserWorkItem ?

最好是另一个 1-Line-Call.如果可能，请使用 Func<> 或 Action<>.<小时>从答案和评论中得到 (b)，我已经更喜欢它了.

Best would be another 1-Line-Call. If possible with use of Func<> or Action<>.

推荐答案

您的问题的答案取决于您如何设计应用程序.你把它放在一个共同的项目中吗?你不想开销一个简单的操作.

The answer for your question depends on how you design the application. Do you put it inside a common project ? you dont want to overhead a simple operations.

但是，您可以为接收参数、1 个参数、2 个参数等的 ThreadPool QueueUserItem 创建一个通用调用.这很好，而不是发送一个简单的字符串并受到限制.

But, You could create a generic call for ThreadPool QueueUserItem that receive params, 1 param, 2 param, etc.. This is good instead of sending a simple string and be restricted.

这就是你如何使用 WaitCallback 实现参数 QueueUserItem:

This how you impl a parameters QueueUserItem with WaitCallback:

ThreadPool.QueueUserWorkItem(
  new WaitCallback(delegate(object state)
  { YourMethod(Param1, Param2, Param3); }), null);

取自 C# Execute Method (with Parameters) with ThreadPool
