BigInteger to Hexadecimal

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

yourBI.ToString("x17").Substring(1) // If you need 16 length

Can you not use yourBI.ToString("X")?

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