这样怎么样:(或者可以这样用吗?)

var test = "Hello";
new Thread(new ThreadStart(() =>
{
    try
    {
        //Staff to do
        Console.WriteLine(test);
    }
    catch (Exception ex)
    {
        throw;
    }
})).Start();

这样怎么样:(或者可以这样用吗?)

var test = "Hello";
new Thread(new ThreadStart(() =>
{
    try
    {
        //Staff to do
        Console.WriteLine(test);
    }
    catch (Exception ex)
    {
        throw;
    }
})).Start();

我建议你学习另一门叫做File的课程。

public class File
{
   private string filename;

   public File(string filename)
   {
      this.filename= filename;
   }

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

在线程创建代码中，你实例化了一个新文件:

string filename = "my_file_name";

myFile = new File(filename);

ThreadStart threadDelegate = new ThreadStart(myFile.download);

Thread newThread = new Thread(threadDelegate);

最简单的就是

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

这样做(相对于ParameterizedThreadStart)的优点是可以传递多个参数，并且可以进行编译时检查，而不需要一直从object进行强制转换。

你也可以这样委派…

ThreadStart ts = delegate
{
      bool moreWork = DoWork("param1", "param2", "param3");
      if (moreWork) 
      {
          DoMoreWork("param1", "param2");
      }
};
new Thread(ts).Start();

你需要为带参数的线程方法使用ParameterizedThreadStart委托。(或者实际上根本没有，让Thread构造函数来推断。)

使用示例:

var thread = new Thread(new ParameterizedThreadStart(download));
//var thread = new Thread(download); // equivalent

thread.Start(filename)
