Saving Data from Dataset to file

Question

I am fairly new at programming in C#. I am using Visual C# 2008 Express, and I have a dataset that I would like to save/export the data to a file. I would like to have that data be saved to either a Text file, or an Excel file. I have not been able to locate how to do this and I completely lost. Any help would be greatly appreciated. This program is a christmas present to my mother who has become quite the collector.
