Base64ToHex () in the code example
I am reading this sample code :
And since I don't know C #, I decided to postpone this.
At compile time, I have this message:
Main.cs(32,65): error CS1061: Type `string' does not contain a definition for `Base64ToHex' and no extension method `Base64ToHex' of type `string' could be found (are you missing a using directive or an assembly reference?)
Compilation failed: 1 error(s), 0 warnings
I have been looking at MSDN and as expected I could not find a link for this method.
Question: Where did this method come from?
ps My code looks like this:
using System.Security.Cryptography;
using System.Text;
using System;
class MainClass
{
public static string Encrypt(string toEncrypt, string key, bool useHashing)
{
..... // same as in post
.....
}
public static void Main( string [] args )
{
string key = "secret";
Console.WriteLine( Encrypt("oscar" + "000", key, true ).Base64ToHex() );
}
}

If this code has ever been executed, Jeff probably had a String extension method called Base64ToHex. Extension methods allow you to define methods to "extend" other classes, so it appears that the method was actually defined in that class:
public static class ExtensionMethods
{
public static string Base64ToHex(this string str)
{
return ...;
}
}

There is System.String
no method Base64ToHex
. I think you are looking for Convert.FromBase64String and BitConverter.ToString :
string encrypted = Encrypt("oscar" + "000", key, true);
Console.WriteLine(BitConverter.ToString(Convert.FromBase64String(encrypted)));
I took a look at your link and I am assuming he wrote an extension helper method that does the same:
public static string Base64ToHex(this string s)
{
return BitConverter.ToString(Convert.FromBase64String(s));
}
