        public Form1()
        {

            words.Add("Ю", "Yu");
            words.Add("Я", "Ya");
    }

        private void button1_Click(object sender, EventArgs e)
        {
            string source = textBox1.Text;
            foreach (KeyValuePair pair in words)
            {
                source = source.Replace(pair.Key, pair.Value);
            }
            textBox2.Text = source;
        }
    }
}

cryllic to latin:

text.Replace(pair.Key, pair.Value); 

latin to cryllic

source.Replace(pair.Value,pair.Key);
