int i=10;
Console.WriteLine("{0:X4}", i);
Outputs hex with a size specifier.
you can also use string interpolation
int i=10;
Console.WriteLine($"{i:X4}");
Int32 num = 1024;
Basic Hex Formatting
Using string interpolation:
Console.WriteLine("{0:X}", num);
Using built-in numeric string formatting:
Console.WriteLine(num.ToString("X"));
400
Fixed Precision Hex Formatting
Console.WriteLine(num.ToString("X4"));
0400
or
Console.WriteLine("0x{0:x8}", num);
0x00000400
