parseInt works in JavaScript, but not in C#

I’m trying to convert this JavaScript code to C#. It is a hexadecimal string that is the value of a crypto token.

Here is what works in JavaScript:

parseInt("0x0000000000000000000000000000000000000000000000056bc75e2d63100000", 16)

Here is what I have tried in C#:

var result = Int16.Parse("0x0000000000000000000000000000000000000000000000056bc75e2d63100000");

I get the error Input string was not in a correct format. What am I doing wrong?

>Solution :

the number is too large for int.

void Main()
{
    string x = "0x0000000000000000000000000000000000000000000000056bc75e2d63100000";
    new System.ComponentModel.Int128Converter().ConvertFromString(x).Dump();
}

result would be 100000000000000000000
