Error in translation

I've written the following code to translate to text

public static string ToText(string input) { List<string> text = new List<string>(input.Length); foreach (char c in input) { try { char morseText = _MorseToText[c.ToString()]; text.Add(morseText.ToString()); } catch (KeyNotFoundException) { text.Add("!"); } } return string.Join(" ", text); }

The problem is its translating wrong. If i input -.-.-- it should produce !, but it produces T E T E TT

Since the loop in this code examines every character individually, every element is being translated to either an E or a T. To get a correct translation, the lookup will need to be performed on complete groups of elements. Try processing the input that way instead.

An example of how this can be done is provided in the "final_code" section of the Project Files download
