There is nothing as evil as sprintf in C#, but a facility similar to ostringstream is StringBuilder. Christian The tragedy of cyberspace - that so much can travel so far, and yet mean so little.

String.Format it takes the same arguments that Console.WriteLine does which allows you to specify some formatting options similar to ?printf. Here is a link to the format string specification.

Thanks. I have another question. Whenever I use a 'String' type in c# most of the times I end up calling the member functions directly without creating any instance are they static methods(for ex. System.String.Format), which in turn return a 'string' type. 'string' is the simple type - does this encapsulate the 'String' type of the framework. Also, I understand I dont have to do a 'new' to access the 'string' types while the 'String' requires a 'new'. Is that true that variables of type 'string' is created in the stack and the 'String' is created in the heap. regards Kannan

Nope, String is a reference type so it is created on the heap. But strings can made Interned since I can't explain it very where here is a copy 'n paste from the docs.
The common language runtime automatically maintains a table, called the "intern pool", which contains a single instance of each unique literal string constant declared in a program, as well as any unique instance of String you add programmatically.The intern pool conserves string storage. If you assign a literal string constant to several variables, each variable is set to reference the same constant in the intern pool instead of referencing several different instances of String that have identical values.This might be what you are thinking of instead of the stack/heap :) James Sonork ID: 100.11138 - Hasaki "Smile your little smile, take some tea with me awhile.
