C#

string [] arr = {"Rahul","Ricky","Pravu"};
    var target = "Pravu";
    var results = Array.FindAll(arr, s => s.Equals(target));

It's a sample for finding string from array.

You can use linq lambda expression

C#

using System.Linq;

            string[] array = { "one", "two" };
//return IEnumerable
            array.Where(o => o == "two");

or as someone stated before via link:

C#

string [] arr = {"One","Two","Three"};
       var target = "One";
       var results = Array.FindAll(arr, s => s.Equals(target));

You could use LINQ to search on it. Like in the next example:

C#

var query = from item in yourStringArray
             where item.Contains("ana") 
             select item; // First you should create the LINQ query;
string firstResult = query.FirstOrDefault(); //Then get the first result from the query!

When i am using your query the firstresult value is true for every string.

I just gave you an example about how to search in the array by using LINQ, and you could modify it as you want, for example to get a list of results not only the first one, bu using "ToList()".
