C# Multicast Delegates - A Practical Example
By Joe Rattz on 11/23/2006 4:04:44 AM

The C# language has a feature known as the multicast delegate.  Any delegate that has a void return type, is a multicast delegate.  A multicast delegate can be assigned and invoke multiple methods.

You may have seen hints of this in your code.  For example, if you are doing ASP.NET development and have ever looked at a page's InitializeComponent() method, you may have noticed a statement like this:

this.SearchButton.Click += new System.EventHandler(this.SearchButton_Click);

Notice the += in that statement.  That is a clue.  You could add another event handler if you wanted, and it would get called as well.  For example, let's say you wanted to also call a method named NotifyStatistics every time the Search button was clicked.  Then your code could be:

All New Articles Will Be Blog Entries From Now On
By Joe Rattz on 11/22/2006 9:59:25 AM

I just noticed the other day that I had several comments on one of my articles.  Some of them had been there for months, but I had not noticed them.  Because the Comments module I use is really a hacked Guestbook module, it doesn't notify me when someone makes a comment.  To better facilitate replies to comments or questions, I decided to find a better way to handle this.  The Blog module seemed the way to go.  So from here on out, all articles will be in my blog.

You can use the site search to search for blog articles, as well as all the older style articles, and anything else on the site for that matter.

Thanks.
