Fortunately, Microsoft has included the solution to the string concatenation problem within the Framework itself.  This solution is in the form of the StringBuilder class, which may be found in the System.Text namespace.

If you are experiencing performance problems with code that performs a lot of string concatenation, then this optimization technique is well worth considering.  Note that a similar technique can also be used with ASP/VBScript and Visual Basic 6.0.  You can either write your own string builder class or use a search engine to find a prewritten algorithm.  This article describes how to implement an equivalent to the StringBuilder class in both VBScript and Visual Basic 6.0.
