Question

I am currently working on a c# project and I need to have a method which has 1 paramater to run as a thread.

E.g.

    public void myMethod(string path)
    {
       int i = 0;
       while (i != 0)
       {
          Console.WriteLine("Number: " + i);
          i++;
       }
    }

How can I call the above method from another method, but running inside a thread.

Thanks for any help you can provide.

Answer 1

The simplest way is generally to use an anonymous method or lambda expression:

string path = ...;

Thread thread = new Thread(() => MyMethod(path));
thread.Start();

You can use a ParameterizedThreadStart, but I generally wouldn’t.

Note that if you do it in a loop, you need to be aware of the normal “closing over the loop variable” hazard:

// Bad
foreach (string path in list)
{
    Thread thread = new Thread(() => MyMethod(path));
    thread.Start();
}

// Good
foreach (string path in list)
{
    string copy = path;
    Thread thread = new Thread(() => MyMethod(copy));
    thread.Start();
}
