如何使用带参数的目标方法将参数传递给ThreadStart?

解决方案

最简单的就是

string 文件名 = ...线程线程=新线程(()=>下载(文件名))；线程.开始()；

这个(相对于ParameterizedThreadStart)的优点是你可以传递多个参数，并且你可以在不需要从object全部转换的情况下进行编译时检查时间.

How to pass parameters to Thread.ThreadStart() method in C#?

Suppose I have method called 'download'

How can I pass parameters to ThreadStart with target method with parameters?

解决方案

The simplest is just

string filename = ...
Thread thread = new Thread(() => download(filename));
thread.Start();

The advantage(s) of this (over ParameterizedThreadStart) is that you can pass multiple parameters, and you get compile-time checking without needing to cast from object all the time.
