C# - listen to add/remove function from event

[bonzaiholding]

how can i know when a function is been added/removed from my Event? I want to do some connection when a COM is add a function to my event.

public delegate void DoItDelegate(int i);
....
....
{
DoItDelegate MyFunction;

MyFunction += new DoItDelegate(DoItFunction);

}

public void DoItFunction(int i)
{
//Do Domthing
}

When the command : "MyFunction += new DoItDelegate(DoItFunction); " is been execute i want to do something in another function. What can i do if i want to know when this "MyFunction += new DoItDelegate(DoItFunction);" is execute and register it to Datatable? (The command "MyFunction += new DoItDelegate(DoItFunction);" is in the COM code and not in my code so i can't control it.)

You mention 'my event' but I don't see any events in your code, only a delegate. If you are using events then you can use the add and remove methods and call your other function there.

public class DoItUser
{
public DoItUser()
{
MyClass myClass = new MyClass();
myClass.MyEvent += new DoItDelegate(DoItFunction);
}

private void DoItFunction(int i)
{
    // ...
}

}

public delegate void DoItDelegate(int i);

public class MyClass
{
private DoItDelegate myEvent;

public event DoItDelegate MyEvent
{
    add
    {
        myEvent += value;
        DoSomethingElse();
    }
    remove { myEvent -= value; }
}

private void DoSomethingElse()
{
    // ...
}

}
