Displaying Text For a Data Value

Question

I am developing a reporting application in Visual Studio 2010 written in C# and I am trying to figure out how to add text into columns when the data is a certain value.  For example, I have a variables column (with values 1-5), and I am wanting the report to display text instead of the numeric values (like: When the value is 1 the report will show Wind Speed, 2 - Temperature, etc.).
