Perhaps not the appropriate group. You should likely try a C# group instead
such as microsoft.public.dotnet.languages.csharp
In addtion to creating a new stringbuilder, it looks like myString.Length=0
should work according to the documentation (myString being actually a
StringBuilder object).
For a String I'm not sure what is your problem. I believe you may have some
confusion between the string and the stringbuilder you called myString ?...

So the problem is to do this quickly (of course it can be done in a
roundabout manner), using either StringBuilder or String. I'm using
C#.NET version 2.0 (Visual Studio 2005). It looks like possibly
there's a new string class introduced in version 3.0 that has
a .remove or .clear public method?!
