Very quick and very dirty:

C#

string k = "Kavin";
string k2 = "";
for(int i = 0; i < k.Length; i++)
{
  string tmp = k.Substring(i, 1);
  if (tmp.ToUpper() == tmp)
    k2 += tmp.ToLower();
  else
    k2 += tmp.ToUpper();
}
MessageBox.Show(k2); //displays "kAVIN"

you beat me to it .:) +5

But you showed me the "IsUpper" and "IsLower" - I hadn't seen them. 5ed you as well :)

like this:

C#

public string ToggleCase(string PstrInput)
        {
            string LstrResult = string.Empty;
            char[] LarrInput = PstrInput.ToCharArray();
            foreach (char LobjChar in LarrInput)
            {
                if (char.IsLower(LobjChar))
                    LstrResult += LobjChar.ToString().ToUpper();
                else if (char.IsUpper(LobjChar))
                    LstrResult += LobjChar.ToString().ToLower();
                else
                    LstrResult += LobjChar.ToString();
            }
            return LstrResult;
        }

And one alternate from me:

C#

public static void InvertCase(ref string strText, out string strInverted)
{
    char[] arrChars = strText.ToCharArray();
    for (int i = 0; i < arrChars.Length; i++)
    {
        if (char.IsLower(arrChars[i]))
            arrChars[i] = (char)((int)arrChars[i] - 32);
        else if (char.IsUpper(arrChars[i]))
            arrChars[i] = (char)((int)arrChars[i] + 32);
    }
    strInverted = new string(arrChars);
}

You can test the method:

C#

string strText = "Kavin", strInverted;
InvertCase(ref strText, out strInverted);
Console.WriteLine("Original: " + strText);
Console.WriteLine("Inverted: " + strInverted);
Console.ReadKey();

The output is:
Original: Kavin
Inverted: kAVIN

Then you should use Nuri Ismail's solution that works without the helping "ToUpper" Method.
