Represent Int64 as a Hexadecimal String in C#

To represent Int64 as a Binary string in C#, use the ToString() method and set the base as the ToString() method’s second parameter i.e.16 for Hexadecimal.

Int64 represents a 64-bit signed integer.

Firstly, set an Int64 variable.

long val = 947645;

Now, convert it to a hex string by including 16 as the second parameter.

Convert.ToString(val, 16)

Example

Live Demo

using System;
class Demo {
   static void Main() {
      long val = 947645;
      Console.WriteLine("Long: "+val);
      Console.Write("Hex String: "+Convert.ToString(val, 16));
   }
}

Output

Long: 947645
Hex String: e75bd
