beginInvoke, GUI and thread

Question

I have application with two thread. One of them (T1) is main GUI form, another (T2) is function working in loop. When T2 gets some information must call function with GUI form. I'm not sure that I do it right.

T2 call function FUNCTION, which update something in GUI form.

  public void f() {
        // controler.doSomething();
  }


 public void FUNCTION() {

    MethodInvoker method = delegate {
            f();
    };

    if ( InvokeRequired ) {
        BeginInvoke( method );
    } else {
            f();
    }
 }

But now I must declare two function. How does it using only one function? Or how does it right.

Answer 1

You can do this in a single method by calling invoking yourself:

public void Function()
{
     if (this.InvokeRequired)
     {
         this.BeginInvoke(new Action(this.Function));
         return;
     }

     // controller.DoSomething();         
}

Edit in response to comments:

If you need to pass additional arguments, you can do it by using a lambda expression as follows:

public void Function2(int someValue)
{
     if (this.InvokeRequired)
     {
         this.BeginInvoke(new Action(() => this.Function2(someValue)));
         return;
     }

     // controller.DoSomething(someValue);         
}
