Introduction:
In my previous article I have explained about Code used to Convert numbers into words using C#.net. In this article I am going to explain about code used to create zip, rar and gzip files using c#.net or how to compress and decompress data using c#.net.

Explanation:
This method is used to generate random string. You can this method to generate random passwords of specified length. For explanation purpose I have a form with a textbox to enter no of characters to generate random string. When you click on the generate button it will automatically generates the random string of specified length.

Below is the method used.
public static string GenerateRandomString(int length)
{
//It will generate string with combination of small,capital letters and numbers
    char[] charArr = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz".ToCharArray();
    string randomString = string.Empty;
    Random objRandom = new Random();
    for (int i = 0; i < length; i++)
    {
        //Don't Allow Repetation of Characters
        int x = objRandom.Next(1, charArr.Length);
        if (!randomString.Contains(charArr.GetValue(x).ToString()))
            randomString += charArr.GetValue(x);
        else
            i--;
    }
    return randomString;
}

To generate the random string with only capital letters then change charArr[] to below.
// to generate random string only with capital letters
char[] charArr = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray();

To generate the random string with only small  letters then change charArr[] to below.
// to generate random string only with small letters
char[] charArr = "abcdefghijklmnopqrstuvwxyz".ToCharArray();

The sample output will be
