如何传递参数的ThreadStart方法主题？

问题描述

如何通过在C＃中的参数 Thread.ThreadStart（）的方法？

假设我有办法叫下载

 公共无效下载（字符串文件名）
{
    //下载code
}
 

在main方法现在，我已经创建了一个线程：

 线程的线程=新主题（新的ThreadStart（下载（文件名））;
 

我如何可以传递参数给的ThreadStart ，目标方法的参数？

解决方案

最简单的就是

 字符串文件名= ...
线程线程=新主题（（）=＆GT;下载（文件名））;
thread.Start（）;
 

的优势（S）这个（超过 ParameterizedThreadStart ）是可以传递多个参数，你会得到编译时检查，而不需要投从对象所有的时间。

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

Suppose I have method called download

public void download(string filename)
{
    //download code
}

Now i have created one thread in main method :

Thread thread = new Thread(new ThreadStart(download(filename));

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.
