replace extended ASCII characters(ISO-8859-1) to mychoice

Question

 Hi Friends,

I am pretty new to .net. I learnt basic and try to implement the same in coding.

 

Now, I need to replace the Extended characters supported by ISO-8859-1 model ( Latin -1) characters to my own choice characters.

 

I need to write a method, So that I can call anywhere. Method should replace existing string that includes latin words into choice of mine.

 

Sample code is attached here. Your suggestions will helpful for me.

 

or Correct me, Where I am going wrong in this code?

 

Thanks

 

Code written is as shown below.

namespace New_Req
{
   public class Program
    {
        static void Main(string[] args)
        {
            StringBuilder s = "€ƒ…†‡‰ŠŒŽ•š";// a sample Latin word to check the functionality
            byte[] ASCIIValues = System.Text.Encoding.Default.GetBytes(s);
            foreach (byte b in ASCIIValues)
            {
              switch(b)
              {
                  case 161:
                            {
                                 var e = Encoding.GetEncoding("ISO-8859-1");
                                 var s = e.GetString(new byte[] { b });
                                 string equivalentLetter = Encoding.Default.GetString(new byte[] { (byte)letter });
                                //!
                                //s.Replace('€',);

                                break;
