See this question: Big integers in C#
From the answer to that question:
MS is going to introduce System.Numerics.BigInteger class in .NET 4.0
Until then, look at IntX class.
IntX is an arbitrary precision integers library written in pure C# 2.0 with fast - O(N * log N) - multiplication/division algorithms implementation. It provides all the basic operations on integers like addition, multiplication, comparing, bitwise shifting etc.
