Hi, In my .NET program I allow a user to define "fields" which are values calculated by the business logic. These fields have a position and length, so that they can all be inserted into a single output string at a given index. I also allow a user to specify default content of this output string.

I've started using StringBuilder in preference to straight concatenation, but it seems like it's missing a crucial method.
