Generic Binary Search in C#

Question

Below is my Generic Binary Search. It works okay with the integers type array (it finds all the elements in it). But the problem arises when I use a string array to find any

Answer 1

pst Your advice really worked. :) this code is working for both int and string.

    public static int BinarySearch(T[] array, T searchFor, Comparer comparer)
    {
        int high, low, mid;
        high = array.Length - 1;
        low = 0;
        if (array[0].Equals(searchFor))
            return 0;
        else if (array[high].Equals(searchFor))
            return high;
        else
        {
            while (low <= high)
            {                   
                mid = (high + low) / 2;
                if (comparer.Compare(array[mid], searchFor) == 0)                   
                    return mid;                    
                else if (comparer.Compare(array[mid], searchFor) > 0)                    
                    high = mid - 1;                    
                else                    
                    low = mid + 1;                  
            }
            return -1;                
        }                 
    }
