多参数线程

尝试使用lambda表达式捕获参数。

Thread standardTCPServerThread = 
  new Thread(
    unused => startSocketServerAsThread(initializeMemberBalance, arg, 60000)
  );

这里有一些代码使用了这里提到的几次对象数组方法。

    ...
    string p1 = "Yada yada.";
    long p2 = 4715821396025;
    int p3 = 4096;
    object args = new object[3] { p1, p2, p3 };
    Thread b1 = new Thread(new ParameterizedThreadStart(worker));
    b1.Start(args);
    ...
    private void worker(object args)
    {
      Array argArray = new object[3];
      argArray = (Array)args;
      string p1 = (string)argArray.GetValue(0);
      long p2 = (long)argArray.GetValue(1);
      int p3 = (int)argArray.GetValue(2);
      ...
    }>

您需要将它们包装成一个单独的对象。

让自定义类传入参数是一个选项。还可以使用对象数组或列表,并在其中设置所有参数。

使用“任务”模式:

public class MyTask
{
   string _a;
   int _b;
   int _c;
   float _d;

   public event EventHandler Finished;

   public MyTask( string a, int b, int c, float d )
   {
      _a = a;
      _b = b;
      _c = c;
      _d = d;
   }

   public void DoWork()
   {
       Thread t = new Thread(new ThreadStart(DoWorkCore));
       t.Start();
   }

   private void DoWorkCore()
   {
      // do some stuff
      OnFinished();
   }

   protected virtual void OnFinished()
   {
      // raise finished in a threadsafe way 
   }
}

.NET 2 jaredpar答案的转换

Thread standardTCPServerThread = new Thread(delegate (object unused) {
        startSocketServerAsThread(initializeMemberBalance, arg, 60000);
    });

你不能。创建一个包含你需要的参数的对象,传递就是它。在thread函数中,将对象强制转换回其类型。

我一直在阅读你的论坛,以了解如何做到这一点,我这样做了-可能对某人有用。我在为我创建工作线程的构造函数中传递参数,该线程将在其中执行我的方法- 执行程序() 方法。

namespace Haart_Trainer_App

{
    class ProcessRunner
    {
        private string process = "";
        private string args = "";
        private ListBox output = null;
        private Thread t = null;

    public ProcessRunner(string process, string args, ref ListBox output)
    {
        this.process = process;
        this.args = args;
        this.output = output;
        t = new Thread(new ThreadStart(this.execute));
        t.Start();

    }
    private void execute()
    {
        Process proc = new Process();
        proc.StartInfo.FileName = process;
        proc.StartInfo.Arguments = args;
        proc.StartInfo.UseShellExecute = false;
        proc.StartInfo.RedirectStandardOutput = true;
        proc.Start();
        string outmsg;
        try
        {
            StreamReader read = proc.StandardOutput;

        while ((outmsg = read.ReadLine()) != null)
        {

                lock (output)
                {
                    output.Items.Add(outmsg);
                }

        }
        }
        catch (Exception e) 
        {
            lock (output)
            {
                output.Items.Add(e.Message);
            }
        }
        proc.WaitForExit();
        var exitCode = proc.ExitCode;
        proc.Close();

    }
}
}

void RunFromHere()
{
    string param1 = "hello";
    int param2 = 42;

    Thread thread = new Thread(delegate()
    {
        MyParametrizedMethod(param1,param2);
    });
    thread.Start();
}

void MyParametrizedMethod(string p,int i)
{
// some code.
}

您可以获取对象数组并在线程中传递它。通过

System.Threading.ParameterizedThreadStart(yourFunctionAddressWhichContailMultipleParameters) 

进入线程构造函数。

yourFunctionAddressWhichContailMultipleParameters(object[])

您已经在objarray中设置了所有值。

你需要 abcThread.Start(objectArray)

您可以用lambda表达式转换“work”函数:

public void StartThread()
{
    // ...
    Thread standardTCPServerThread = new Thread(
        () => standardServerThread.Start(/* whatever arguments */));

    standardTCPServerThread.Start();
}

您需要传递单个对象,但如果定义自己的对象以供单独使用太麻烦,则可以使用 元组 .
