Question

我需要同时向网络服务提出多重要求。我想为每一项请求打下一条线。可以在伙伴关系中做到这一点。 NET v3.5?

Example:

for(int i = 0; i<=10; i++)
{
   "Do each Request in a separate thread..."
}

Answer 1

以下模式可用于将多项申请作为<代码>ThreadPool中的工作项目。它还将等待所有这些工程项目在进行之前完成。

int pending = requests.Count;
var finished = new ManualResetEvent(false);
foreach (Request request in requests)
{
  Request capture = request; // Required to close over the loop variable correctly.
  ThreadPool.QueueUserWorkItem(
    (state) =>
    {
      try
      {
        ProcessRequest(capture);
      }
      finally
      {
         if (Interlocked.Decrement(ref pending) == 0) 
         {
           finished.Set();  // Signal completion of all work items.
         }
      }
    }, null);
}
finished.WaitOne(); // Wait for all work items to complete.

也可下载Reactive extensions Backport for 3.5,然后使用Parallel。 做同样的事情。

Answer 2

While the oportunities to what you can use vary depending of what and where you would like to use paralelism in your code. I would suggest that you start off by using the new Task class from .NET 4.0. Example would be:

Task backgroundProcess = new Task(() =>
                {
                    service.CallMethod();
                });

这将促使你开始。之后,我建议你做一些读物,因为这是一个非常广泛的主题。查询这一联系:

Answer 3

如果网络服务电话过于仓促,我看不出有多条read子会取得什么成就。

Answer 4

表3.5 用户工作项目方法。网上的例子很多。
