I'm not entirely sure what you mean, but if you're talking about an EventArgs derived class:

public class MyEventArgs : EventArgs
{
    private string m_Data;
    public MyEventArgs(string _myData)
    {
        m_Data = _myData;
    } // eo ctor

    public string Data {get{return m_Data} }
} // eo class MyEventArgs


public delegate void MyEventDelegate(MyEventArgs _args);

public class MySource
{
    public void SomeFunction(string _data)
    {
        // raise event
        if(OnMyEvent != null) // might not have handlers!
            OnMyEvent(new MyEventArgs(_data));
    } // eo SomeFunction
    public event MyEventDelegate OnMyEvent;
} // eo class mySource

Hope this helps.
