Hexadecimal equivalent of SharePoint Base Permissions

Sometimes we need hexadecimal equivalent of SharePoint permission levels. These values can be very useful to make UI changes through JavaScript/JQuery based on current logged-in user’s permission level.
I used the following code in a C# console application to get the hexadecimal equivalent of permission levels:

using System;
using Microsoft.SharePoint;

namespace GetSPBasePermissions
{
class Program
{
static void Main(string[] args)
{
foreach (SPBasePermissions enm in Enum.GetValues(typeof(SPBasePermissions)))
{
string enmName = enm.ToString();
string enumValue = String.Format("0x{1:X}",
enmName, (UInt64)Enum.Parse(typeof(SPBasePermissions), enmName));
Console.WriteLine(enmName + " : " + enumValue);
}
Console.ReadLine();
}
}
}


This program will give the following output:
