I have this value in hexadecimal "E365A931A000000".
I need to convert it to integer I'm using the following code.
string hex = "E365A931A000000";
CodLibercao = Convert.ToInt32(hex);
This code is giving me the following exception:
"Input string was not a correct format."
What am I doing wrong in the conversion?
You were not able to use the conversion base. There is also a problem because this number does not fit into a int , you must use a long ( Convert.ToInt64() ) to perform the conversion.
using System;
using System.Numerics;
using System.Globalization;
public class Program {
public static void Main() {
var hex = "E365A931A000000";
Console.WriteLine(Convert.ToInt64(hex, 16));
hex = "E365A931";
Console.WriteLine(Convert.ToInt32(hex, 16));
hex = "E365A931A000000000";
Console.WriteLine(BigInteger.Parse(hex, NumberStyles.HexNumber));
}
}
See working on dotNetFiddle .
I showed an example with a smaller number to fit in int . And a conversion that accommodates numbers of any size. You should evaluate whether it's worth using BigInteger .
In fact converting from hexadecimal to integer requires the use of Parse , more specifically this format :
var codLiberacao = int.Parse(hex, System.Globalization.NumberStyles.HexNumber);
I just did a test and this hex is too large for a 32-bit integer , then use long or Int64 for conversion:
var codLiberacao = Int64.Parse(hex, System.Globalization.NumberStyles.HexNumber);
