We will either end up with a buffer that's too large (wasted space) or, worse, a buffer that's too small, which must keep expanding as we generate the complete string. In this scenario, it might be best to use one of the various string class formatting methods.

There are three string class methods available for generating strings: string.Format(), string.Join(), and string.Concat(). Each operates slightly differently, but the overall output is the same.
