And what have you tried already? Did you go and see the BigInteger class properties and methods on MSDN?

try with System.Numerics.BigInteger.Parse method

VB

Dim result = System.Numerics.BigInteger.Parse("10ABC345DE7859410ABC39410ABC34545DE78DE7FA4545DE78DE7FABD12345", System.Globalization.NumberStyles.AllowHexSpecifier)

This below example:
Compare to different BigInteger's Code:

BigInteger number1 = BigInteger.Pow(Int64.MaxValue, 100);
BigInteger number2 = number1 + 1;
string relation = "";
switch (BigInteger.Compare(number1, number2))
{
case -1:
relation = "<";
break;
case 0:
relation = "=";
break;
case 1:
relation = ">";
break;
}
Console.WriteLine("{0} {1} {2}", number1, relation, number2);
