Metoda C# Compare() koristi se za leksikografsku usporedbu prvog niza s drugim nizom. Vraća vrijednost cijelog broja.
Ako su oba niza jednaka, vraća 0. Ako je prvi niz veći od drugog niza, vraća 1, inače vraća -1.

Primjer metode C# String Compare().
using System; public class StringExample { public static void Main(string[] args) { string s1 = 'hello'; string s2 = 'hello'; string s3 = 'csharp'; string s4 = 'mello'; Console.WriteLine(string.Compare(s1,s2)); Console.WriteLine(string.Compare(s2,s3)); Console.WriteLine(string.Compare(s3,s4)); } } Izlaz:
0 1 -1
