Rule

s1==s2 returns 0
s1>s2 returns positive number in difference
s1<s2 returns negative number in difference

Signature

public static int CompareOrdinal(String first, String second)
public static int CompareOrdinal(String, Int32, String, Int32, Int32)

Parameters

first: first argument represents string which is to be compared with second string.

            Console.WriteLine(string.CompareOrdinal(s1,s2)); 
            Console.WriteLine(string.CompareOrdinal(s1,s3)); 
            Console.WriteLine(string.CompareOrdinal(s1,s4)); 
        }  
    }
