BigInteger to Hexadecimal

Question

Quick question...

I have a stupidly long BigInteger which I would like to write to a file as a hex string.

I know Java provides the .toString(16) method which does this, but I can't find an equivalent in C#.

I'm using System.Numerics.BigInteger from .NET 4.0.

Thanks

Use .ToString("X") or .ToString("x") depending on what case you prefer.
