hi friends,

How to write linq to find out supplied set of values exists in an array. eg:-

string[] letters = { "A", "B", "C", "D", "E", "F", "G" };
bool IsMatch =
    (from n in letters where new string[] { "B", "X" }
         .Contains(n) select n)
         .Count() == new string[] { "B", "X" }.Count();

the above code return false and its work as expected, but i am looking for a better code.

thanks,
achu.

achu,

I've pulled out the second array for clarity.  I think your code is fine, but you could use the Intersect extension if you wanted:

string[] test = { "B", "X" };

(from n in letters select n).Intersect(from t in test select t).Count() == test.Count();

thanks james.
