How can I use bigint with C#?

Question

I work to implement an RSA key algorithm. But I couldn\'t use a 2048-bit value. How I can use it?

I want to use big integer.

Answer 1

Native support for big integers has been introduced in .NET 4.0. Just add an assembly reference to System.Numerics, add a using System.Numerics; declaration at the top of your code file, and you’re good to go. The type you’re after is BigInteger.
