Question

What is the C# equivalent of Integer.toHexString() from Java?

Answer 1

Use String.Format("{0:x}", x) static method or Int32.ToString("x") method.

see the example:

using System;
using System.Globalization;

class Program
{
static void Main()
{
    int x = 4067;
    string s = x.ToString("x");
    Console.WriteLine(s);      // fe3

    s = String.Format("{0:x}", x);
    Console.WriteLine(s);      // fe3

    s = String.Format("{0:X}", x);
    Console.WriteLine(s);      // FE3

    s = String.Format("{0:x6}", x);
    Console.WriteLine(s);      // 000fe3
}
}
