Max integral type in C#

Question

I can't seem to find an integral type that this will work on:

string foo = "9999999999999999999999999999999999999999999999999999999";

long value;
if(long.TryParse(foo, out value))
{
   // do something
}

Answer 1

In .NET 4 you can use System.Numerics.BigInteger which has a TryParse method.

See: http://msdn.microsoft.com/en-us/library/system.numerics.biginteger.aspx

Answer 2

Yes, .NET 4.0 introduces BigInteger which is arbitrarily large and supports TryParse, of course.

Answer 3

There is not a primative type that will work for that. But there is a new BigInteger class introduced in .NET 4.
