eventhandler

Hi, On the MSDN, I have found following:

public event EventHandler<MyEventArgs> SampleEvent;

public void DemoEvent(string val)
{
// Copy to a temporary variable to be thread-safe.
    EventHandler<MyEventArgs> temp = SampleEvent;
    if (temp != null)
        temp(this, new MyEventArgs(val));
}

I do not understand, "copy to temporary variable", isnt it reference type?

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
