How to extract matching strings from two string arrays (C#.net):

 

For example: You have the following two string arrays and you want extract the matching strings from both. Then through LINQ you can do this: In this particular example “is”, “bad” and “boy” are same in both strings.

 

string[] str1 = new String[] { "osama", "is", "bad", "boy" };

string[] str2 = new String[] { "is", "awesome", "bad", "boy" };

Code 

In the query: what we are doing is this: matching each string in str1 on str2.

 

      List<string> lst =

            (from String s in str1

             where str2.Contains(s)

             select s).ToList();

Displaying the list:

 

      foreach (var item in lst)

          Console.WriteLine(item);

Output of the program is:

              is

              bad
