In my web application, i have two strings and i need to display modified words and count between them.For example:


    string variable1="When you are writing server code you can never be sure what the IP address you see is refereeing to.In fact some users like it this way.";
    string variable2="When you are wrting server code yu cannn never be sure what the IP address you see is refering to.In fact some users like it this way";

    the result should be, modified words : wrting,yu ,cannn ,refering 
                          modified words count :4

how to do this can anyone tell me.

Thank you

What I have tried:

var result2 = variable2.Split(new char[] { ' ' }).Except(variable1.Split(new char[] { ' ' })).ToArray();

count = result2.Length;

Label3.Text = "Modified Word: " + result2[0].ToString() + "
" + "Modified Count: " + count.ToString();

try this

C#

string variable1 = "When you are writing server code you can never be sure what the IP address you see is refereeing to.In fact some users like it this way.";
      string variable2 = "When you are wrting server code yu cannn never be sure what the IP address you see is refering to.In fact some users like it this way";


      string[] var1Words = variable1.Split(' ');
      string[] var2Words = variable2.Split(' ');


      string modified = "";
      List<string> lstModifiedWords = new List<string>();
      if (var1Words.Length == var1Words.Length)
      {
          for (int i = 0; i < var1Words.Length; i++)
              if (var1Words[i] != var2Words[i])
                  lstModifiedWords.Add(var1Words[i]);
      }
      modified = "Modified words:" + string.Join(",", lstModifiedWords) + " Modified Count:" + lstModifiedWords.Count;

Hi
you could split each string into an array as such, then check the counts of each array. Then check the counts to see which one is greater something has been changed in terms of length of words.

C#

class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(string.Join(", ",Program.getDifferences("MY STRING IS GREAT", "MY STRING IS AWESOME")));
            Console.WriteLine(string.Join(", ", Program.getDifferences("MY STRING IS GREAT", "MY STR1NG IS GR3AT")));
            Console.ReadKey();

        }

        public static List<string> getDifferences(string StartString, string EndString)
        {
            //Split out
            IEnumerable<string> startStringSet = StartString.Split(' ');
            IEnumerable<string> endStringSet = EndString.Split(' ');

            if (StartString.Count() == 0 && endStringSet.Count() == 0)
            {
                //Return Empty List
                return new List<string>();
            }
            else if (startStringSet.Count() < endStringSet.Count())
            {
                //Return list excluding items in the End String
                return endStringSet.Except(startStringSet).ToList();
            }
            else
            {
                //Return list excluding items in the starting string
                return endStringSet.Except(startStringSet).ToList();
            }

        }
    }

Output Is:

AWESOME
STR1NG, GR3AT

Hope it helps
