1) 您可能应该使用线程池或任务(Fx4)

2) 当您可以使用代理lamba'a(.NET 3及更高版本)时

对于旧版本,可以使用和辅助对象来保持开始和结束


编辑以调整循环:

for (int i = 0; i < threadCount; i++)
{
   // some code to update intStartIp, intEndIp 

   //threads[i] = new Thread(new ThreadStart(getPerformance));                  
   threads[i] = new Thread(() => getPerformance(intStartIp, intEndIp));
   threads[i].Name = string.Format(i.ToString());   
}
for(int i=0;igetPerformance(intStartIp,intEndIp));
线程[i].Name=string.Format(i.ToString());
}

平台、语言?它看起来像是C#,但提到它只是一个小小的努力。很抱歉我忘了它,现在已编辑..getPerformance将在非ui线程上执行,因此对progressBar1的更改将不起作用。此外,多个线程可能同时更改属性,使粘贴的代码容易出现线程问题。平台、语言?它看起来像是C#,但提到它只是一个小小的努力。很抱歉我忘了它,现在已编辑..getPerformance将在非ui线程上执行,因此对progressBar1的更改将不起作用。此外,多个线程可能同时更改属性,使粘贴的代码容易出现线程问题。我可以将其用于多线程吗?因为这个“t”变量不是数组类型,我可以将它用于多线程吗?因为这个“t”变量不是数组类型
