Basic String Operations in .NET

Applications often respond to users by constructing messages based on user input. For example, it is not uncommon for Web sites to respond to a newly logged-on user with a specialized greeting that includes the user's name. Several methods in the System.String and System.Text.StringBuilder classes allow you to dynamically construct custom strings to display in your user interface. These methods also help you perform a number of basic string operations like creating new strings from arrays of bytes, comparing the values of strings, and modifying existing strings.
