如何获取C#中正在运行的线程的列表? [英] How do you get list of running threads in C#?

问题描述

我在C#中创建动态线程，我需要获取那些正在运行的线程的状态.

I create dynamic threads in C# and I need to get the status of those running threads.

List<string>[] list;
list = dbConnect.Select();

for (int i = 0; i < list[0].Count; i++)
{
    Thread th = new Thread(() =>{
        sendMessage(list[0]['1']);
        //calling callback function
    });
    th.Name = "SID"+i;
    th.Start();
}

for (int i = 0; i < list[0].Count; i++)
{
    // here how can i get list of running thread here.
}

推荐答案

创建一个List<Thread>并将每个新线程存储在其中的第一个for循环中.

Create a List<Thread> and store each new thread in your first for loop in it.

List<string>[] list;
List<Thread> threads = new List<Thread>();
list = dbConnect.Select();

for (int i = 0; i < list[0].Count; i++)
{
    Thread th = new Thread(() =>{
        sendMessage(list[0]['1']);
        //calling callback function
    });
    th.Name = "SID"+i;
    th.Start();
    threads.add(th)
}

for (int i = 0; i < list[0].Count; i++)
{
    threads[i].DoStuff()
}

但是，如果不需要i，则可以将第二个循环设置为foreach而不是for

However if you don't need i you can make the second loop a foreach instead of a for

作为旁注，如果您的sendMessage函数执行时间不会很长，则应该减轻重量，然后减轻整个线程的负担，请使用

As a side note, if your sendMessage function does not take very long to execute you should somthing lighter weight then a full Thread, use a ThreadPool.QueueUserWorkItem or if it is available to you, a Task
