Question

In order to represent the method that executes on a thread I am using
ParameterizedThreadStart and passing the name of the method. In this case the method name is SelectJob and the instantiation is as follows:

ParameterizedThreadStart starter = new ParameterizedThreadStart(SelectJob);

protected void SelectJob(object index)
{
     ...
}

In order to reuse a portion of code I would like, if possible, to store the method name in a variable but the IntelliSense shows the method signature for ParameterizedThreadStart as ParameterizedThreadStart(void (object) target) and I’m not sure how I could store this sort of value. From MSDN I realize this is a delegate so after reading How to: Declare, Instantiate, and Use a Delegate I tried to declare …

delegate void Del(string str);
Del selectDelegate = SelectJob;

… but since the SelectJob method is not static I am not able to do this. Simply making the method static is not an easy option.

Is there another way of making this declaration?

Thanks!

Answer 1

Initialise the delegate instance inside a constructor?

public class MyClass
{
    private ParameterizedThreadStart starter;

    public MyClass()
    {
        starter = SelectJob;

        Del selectDelegate = SelectJob;
    }

    delegate void Del(string str);

    protected void SelectJob(object index)
    {

    }
}
