Random Password generation using C#.NET

[z07924]

// Random Password Generation

VB.NET
Randomize()
whatsNext = Int((1 - 0 + 1) * Rnd() + 0)
strNewPass = strNewPass & Chr(Int((upper - lower + 1) * Rnd() + lower))

The above two lines are in visual basic.net. I have converted the above lines to C#.NET. It is given below.

C#.NET
Random RandomGenerator = new Random(20);
whatsNext = (int)((1 - 0 + 1) * RandomGenerator.Next() + 0);
strNewPass = strNewPass + (char)((int)((upper - lower + 1) * RandomGenerator.Next() + lower));

I have tried the same code executing in VB.NET, it is working fine. somehow I couldn't get the same result when I have tried in C#.NET.

Is there anything wrong?
If anyone know the solution, let me know.

Thanks in Advance.

The Rnd and Random methods are language-specific, so I'm not surprised they act differently.

If you want something truly random, investigate the System.Security.Cryptography namespace. It has a class named RNGCryptoServiceProvider, which has a method named GetBytes.

Since this method is part of the framework, not part of the language, it will work the same no matter which .NET language you use.
