Comment puis-je convertir la chaîne cyrillique en anglais en C #

Cette méthode est très rapide:

static string[] CyrilicToLatinL = 
  "a,b,v,g,d,e,zh,z,i,j,k,l,m,n,o,p,r,s,t,u,f,kh,c,ch,sh,sch,j,y,j,e,yu,ya".Split(',');
static string[] CyrilicToLatinU = 
  "A,B,V,G,D,E,Zh,Z,I,J,K,L,M,N,O,P,R,S,T,U,F,Kh,C,Ch,Sh,Sch,J,Y,J,E,Yu,Ya".Split(',');

public static string CyrilicToLatin(string s)
{
  var sb = new StringBuilder((int)(s.Length * 1.5));
  foreach (char c in s)
  {
    if (c >= '\x430' && c <= '\x44f') sb.Append(CyrilicToLatinL[c - '\x430']);
    else if (c >= '\x410' && c <= '\x42f') sb.Append(CyrilicToLatinU[c - '\x410']);
    else if (c == '\x401') sb.Append("Yo");
    else if (c == '\x451') sb.Append("yo");
    else sb.Append(c);
  }
  return sb.ToString();
}

C'est une solution pour la translittération serbe cyrillique-latine pour la forme comme celle-ci: formulaire

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        Dictionary<string, string> slova = new Dictionary<string, string>();

        public Form1()
        {
            InitializeComponent();
            slova.Add("Љ", "Lj");
            slova.Add("Њ", "Nj");
            slova.Add("Џ", "Dž");
            slova.Add("Ñ™", "lj");

            slova.Add("ч", "č");
            slova.Add("ш", "š");
        }

        // Method for cyrillic to latin
        private void button1_Click(object sender, EventArgs e)
        {
            string source = textBox1.Text;
            foreach (KeyValuePair<string, string> pair in slova)

                source = source.Replace(pair.Key, pair.Value);
                // For upper case
                source = source.Replace(pair.Key.ToUpper(),

            }
            textBox2.Text = source;
        }

        // Method for latin to cyrillic
        private void button2_Click(object sender, EventArgs e)
        {
            string source = textBox2.Text;
            foreach (KeyValuePair<string, string> pair in slova)
            {
                source = source.Replace(pair.Value, pair.Key);
                // For upper case
                source = source.Replace(pair.Value.ToUpper(),
