gistfile1.cs

class Program
{
	static void Main(string[] args)
	{
		Spelling spelling = new Spelling();
		string word = "";

		word = "speling"; 
		Console.WriteLine("{0} => {1}", word, spelling.Correct(word));

		word = "korrecter"; // 'correcter' is not in the dictionary file so this doesn't work
		Console.WriteLine("{0} => {1}", word, spelling.Correct(word));

		word = "korrect";
		Console.WriteLine("{0} => {1}", word, spelling.Correct(word));

		word = "acess";
		Console.WriteLine("{0} => {1}", word, spelling.Correct(word));

		word = "supposidly";
		Console.WriteLine("{0} => {1}", word, spelling.Correct(word));

		// A sentence
		string sentence = "I havve speled thes woord wwrong"; // sees speed instead of spelled (see notes on norvig.com)
		string correction = "";
		foreach (string item in sentence.Split(' '))
		{
			correction += " " +spelling.Correct(item);
		}
		Console.WriteLine("Did you mean:" + correction);

		Console.Read();
	}
