"Ferb" Latin encoder :) [In .NET/C#]

In the previous post, I had mentioned about the "Pig" latin, which offers some sort of "Perceived" privacy. This morning when I was watching Phineas and Ferb, they invent a new language called "Ferb" latin, so I thought since very less people know about that, we can very well use those rules instead. Here is the program to encode:

public static string GetFerbLatinFromText(string strText)

{

    string strRetVal = string.Empty;

    int i, j;

    try

    {

        StringBuilder sb = new StringBuilder();

        char[] chrLetters;

        string[] strWord = strText.Split(' ', '\n');

        for (i = 0; i < strWord.Length; i++)

        {

            chrLetters = strWord[i].ToCharArray();

            if (chrLetters.Length > 2)

            {

                for (j = 1; j < chrLetters.Length; j++)

                {

                    sb.Append(Char.ToLower(chrLetters[j]));

                }

                sb.Append(Char.ToLower(chrLetters[0]));

                sb.Append("erb ");

            }

            else

            {

                sb.Append(strWord[i]);

                sb.Append(" ");

            }

        }

        strRetVal = sb.ToString();

    }

    catch (Exception exp)

    {

        throw exp;

    }

    return strRetVal;

}

Code to decode the text :

public static string GetTextFromFerbLatin(string strText)

{

    string strRetVal = string.Empty;

    int i, j;

    try

    {

        StringBuilder sb = new StringBuilder();

        char[] chrLetters;

        string[] strWord = strText.Split(' ', '\n');

        for (i = 0; i < strWord.Length; i++)

        {

            chrLetters = strWord[i].ToCharArray();

            if (chrLetters.Length > 2)

            {

                if(chrLetters.Length >4)

                    sb.Append(Char.ToLower(chrLetters[chrLetters.Length - 4]));

                for (j = 0; j < chrLetters.Length-4; j++)

                {

                    sb.Append(Char.ToLower(chrLetters[j]));

                }

                sb.Append(' ');

            }

            else

            {

                sb.Append(strWord[i]);

                sb.Append(" ");

            }

        }

        strRetVal = sb.ToString();

    }

    catch (Exception exp)

    {

        throw exp;

    }

    return strRetVal;

}
