C# Random String Generators

Heres a little bit of code for making random strings. I’m sure someone will find it useful. I used to use it a lot in web development. Not sure how useful it would be for software development but use it if you’d like to


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Ruf
{
public static class StringGnerator
{
public static Char[] charArray = { ‘-’, ‘a’, ‘b’, ‘c’, ‘d’, ‘e’, ‘f’, ‘g’, ‘h’, ‘i’, ‘j’, ‘k’, ‘l’, ‘m’, ‘n’, ‘p’, ‘q’, ‘r’, ’s’, ‘t’, ‘u’, ‘v’, ‘w’, ‘x’, ‘y’, ‘z’, ‘1′, ‘2′, ‘3′, ‘4′, ‘5′, ‘6′, ‘7′, ‘8′, ‘9′, ‘0′, ‘_’ };

public static string RandomStr()
{
String returns = “”;
Random r = new Random();
for (int i = 0; i < 11; i++)
{
returns += “” + charArray[(int)(r.NextDouble() + 1.0 * 38.0)];
}
return returns;
}

public static string RandomStr(int Length)
{
String returns = “”;
Random r = new Random();
for (int i = 0; i < Length; i++)
{
returns += “” + charArray[(int)(r.NextDouble() + 1.0 * 38.0)];
}
return returns;
}

public static string RandomStr(int Seed, int Length)
{
String returns = “”;
Random r = new Random(Seed);
for (int i = 0; i < Length; i++)
{
returns += “” + charArray[(int)(r.NextDouble() + 1.0 * 38.0)];
}
return returns;
}

}
}
