How to compare string with another string using c#

Question

I have a situation where i don't want to compare total string length to other string .

Example:

string MainString = "Deanna Ecker";

string SearchString = "Ecker Designs";

int value = MainString.IndexOf(SearchString);

here it is searching with whole string. but i need to find any word in MainString. not with whole string..

Let me know how is this possible.

given answers solve your problem. if you are also interested in matching words like "apple" with "apples" or "aple", en.wikipedia.org/wiki/Levenshtein_distance — Exceptyon

If case-sensitivity is not an issue, you could split both strings by the space, then intersect the two lists to see if there are any matches:

var foundWords = MainString.Split(' ').Intersect(SearchString.Split(' '));

Or if you only want to know if a word was found:

var isMatch = MainString.Split(' ').Intersect(SearchString.Split(' ')).Any();

you can convert your string to a char array then search each character via looping from all characters such that

public bool MatchString(string first,string second)
{
  char[] ch1=first.ToCharArray();
  char[] ch2=second.ToCharArray();
  bool match=false;
  for(int i=0 ; i<ch1.length ; i++)
   {
      for(int j=0 ; j<ch2.length ; j++)
       {
             if(ch2[j]==ch[i])
              {
                match=true;
                break;
              } 
       }
   }
 return match;
}

Try: var wordMatch = MainString.Split(' ').Intersect(SearchString.Split(' ')).Any();
