Metoda C# Compare() se uporablja za leksikografsko primerjavo prvega niza z drugim nizom. Vrne celoštevilsko vrednost.
Če sta oba niza enaka, vrne 0. Če je prvi niz večji od drugega niza, vrne 1, sicer vrne -1.
Pravilo
s1==s2 returns 0 s1>s2 returns 1 s1<s2 returns -1 < pre> <h3>Signatures</h3> <pre> public static int Compare(String first, String second) public static int Compare(String, Int32, String, Int32, Int32) public static int Compare(String, Int32, Int32, String, Int32, Boolean) public static int Compare(String, Boolean, Int32, Int32, String, Int32, CultureInfo) public static int Compare(String, CultureInfo, Int32, Int32, String, Int32, CompareOptions) public static int Compare(String, Int32, Int32, String, Int32, StringComparison) public static int Compare(String, String, Boolean) public static int Compare(String, String, Boolean, CultureInfo) public static int Compare(String, String, CultureInfo, CompareOptions) public static int Compare(String, String, StringComparison) </pre> <h3>Parameters</h3> <p> <strong>first:</strong> first argument represents string which is to be compared with second string.</p> <p> <strong>second:</strong> second argument represents string which is to be compared with first string.</p> <h3>Return</h3> <p>It returns an integer value.</p> <hr> <h2>C# String Compare() Method Example</h2> <pre> 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)); } } </pre> <p> <strong>Output:</strong> </p> <pre> 0 1 -1 </pre></s2> Parametri
prvi: prvi argument predstavlja niz, ki ga je treba primerjati z drugim nizom.

Primer 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)); } } Izhod:
0 1 -1
