Do you mean a MS Word document or a text document. If you want to read a
text document the following is the snippet, you could

       string path = @"c:\temp\temp.txt";

       // This text is added only once to the file.
       if (!File.Exists(path))
           throw new FileNotFoundException("File not found");

       // Open the file to read from to read line by line and storing it
in an array.
       string[] readText = File.ReadAllLines(path);
       foreach (string s in readText)
           Console.WriteLine(s);

       // Open the file to read from to read the entire contents into a
string
       string text = File.ReadAllText(path);
       Console.WriteLine(text);
