How do I pass overloaded funtions to another class?

Question

I have two variations of UpdateStatusLine:

public delegate void DelegateUpdateStatusLine(String text);
private DelegateUpdateStatusLine m_DelegateUpdateStatusLine;
public delegate void DelegateUpdateStatusLine(String text, int percentage);

private void UpdateStatusLine(String text)
	{ ... }
private void UpdateStatusLine(String text, int percentage)
	{ ... }

I need to pass the delegate to another class that will use both overloads. Passing either one is simple.

m_DelegateUpdateStatusLine = new DelegateUpdateStatusLine(this.UpdateStatusLine);
AnotherClass x = new AnotherClass(m_DelegateUpdateStatusLine);

How do I pass delegates that allow AnotherClass to use either form of UpdateStatusLine?

You can have both the overloaded methods in the same class. There is no restriction on that.
You can they simply call just the one you want!

My 5. Weird question. Maybe the very inaccurate term "overload" is confusing. Bat term!

Hey there,

Delegates are somewhat similar to Pointers in C. All they does is point at something and they don't contain logic. Therefore, it cannot point at 2 things at once and assuming it can, since it got no logic it wouldn't be able to figure out which one to call.

There are 2 approaches based on my opinion:
1. To create the overloaded method with default parameters and pass that method in the delegate. You have to write logic to see whether a certain parameter is assigned or it stay the default value.
2. You've figured out the way to do it for one method. Why not do it to the other overload as well and pass the same way? I.e. you'd have 2 parameters.

Hope this helps, regards
