I am in need of generating a random string with spaces and mixedCase.

This is all I got so far:

The easiest way to do this is to simply create a string with the following values:

private readonly string legalCharacters = " abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";

Then use the RNG to access a random element in this string:

public string TypeAway(int size)
{
    StringBuilder builder = new StringBuilder();
    Random random = new Random();
    char ch;

    for (int i = 0; i < size; i++)
    {
        ch = legalCharacters[random.Next(0, legalCharacters.Length)];
        builder.Append(ch);
    }

    return builder.ToString();
}
