Takeaway: Irina Medvinskaya explains how you use Visual Studio .NET's System.URI class to work with Uniform Resource Identifiers (URIs). This class allows you to represent and easily manipulate a given URI.

Uniform Resource Identifiers (URIs) may represent Web requests, FTP requests, files, news, and e-mail. Whenever you need to work with URIs and determine a particular portion of a given URI, you can utilize the System.URI class available in Visual Studio .NET. This class allows you to represent and easily manipulate a given URI.

To create an example, add a ListBox control to your form and call it ListBox1. Then, add the code in Listing A. The result of running this code looks like Figure 1.

In the code, I initially define a strURI variable and set its value to a link from the TechRepublic site. Then, I add the following properties of the URI object strURI to the ListBox1 control: Scheme, Host, Path, Query, Type, Port. The ListBox1 control simply displays the selected properties of the strURI object.
