Question

Answer 1

Not sure how well this will scale to a big word list, but I think it should give the output you want (although in your question the 'result' seems identical to 'content')?

Anyway, let me know if this is what you're after

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var input = @"This is just a little test of the memb to see if it gets picked up. 
Deb of course should also be caught here.";
            var dictionary = new Dictionary
            {
                {"memb", "Member"}
                ,{"deb","Debut"}
            };
            var regex = "(" + String.Join(")|(", dictionary.Keys.ToArray()) + ")";
            foreach (Match metamatch in Regex.Matches(input
               , regex  /*@"(memb)|(deb)"*/
               , RegexOptions.IgnoreCase | RegexOptions.ExplicitCapture))
            { 
                input = input.Replace(metamatch.Value, dictionary[metamatch.Value.ToLower()]);
            }
            Console.Write (input);
            Console.ReadLine();
        }
    }
}
