Converting a string into BigInteger

Question

I have the following code that creates a very big number (BigInteger) which is converted then into a string.

// It\'s a console app         


        

Answer 1

Here is another approach which is faster compared to BigInteger.Parse()

public static BigInteger ToBigInteger(string value)
{
    BigInteger result = 0;
    for (int i = 0; i < value.Length; i++)
    {
        result = result * 10 + (value[i] - '0');
    }
    return result;
}
