Answer 1

To find the substrings in the String array using C#

    List searchitem = new List();
    string[] arrayStrings = {
       "Welcome to SanJose",
       "Welcome to San Fancisco","Welcome to New York",
       "Welcome to Orlando", "Welcome to San Martin",
       "This string has Welcome to San in the middle of it"
    };
   string searchkey = "Welcome to San";
   for (int i = 0; i < arrayStrings.Length; i++)
   {
    if (arrayStrings[i].Contains(searchkey))//checking whether the searchkey contains in the string array
    {
     searchitem.Add(arrayStrings[i]);//adding the matching item to the list 
    }
   string searchresult = string.Join(Environment.NewLine, searchitem);

Output for Searchresult:

Welcome to SanJose

Welcome to San Fancisco

Welcome to San Martin

This string has Welcome to San in the middle of it
