C#의 CompareOrdinal() 메서드는 각 문자열에서 해당 Char 개체의 숫자 값을 평가하여 지정된 두 String 개체를 비교하는 데 사용됩니다.
구문
public static int CompareOrdinal (string str1, string str2);
위의 str1과 str2는 비교할 문자열입니다.
반환 값은 0보다 작습니다(str1
예시
using System; public class Demo { public static void Main(string[] args) { string s1 = "Amy"; string s2 = "Katie"; string s3 = s2; Console.WriteLine("String1 = "+s1); Console.WriteLine("String2 = "+s2); Console.WriteLine("Are both the strings equal? = "+s1.Equals(s2)); Console.WriteLine("Are both the strings equal? = "+s2.Equals(s3)); Console.WriteLine(string.CompareOrdinal(s1, s2)); Console.WriteLine(string.CompareOrdinal(s2, s3)); } }
출력
String1 = Amy String2 = Katie Are both the strings equal? = False Are both the strings equal? = True -10 0
예시
using System; public class Demo { public static void Main(string[] args) { string s1 = "David"; string s2 = "David"; string s3 = s2; string s4 = "Tom"; string s5 = s4; Console.WriteLine("String1 = "+s1); Console.WriteLine("String2 = "+s2); Console.WriteLine("String3 = "+s3); Console.WriteLine("String4 = "+s4); Console.WriteLine("String5 = "+s5); Console.WriteLine("Is s1 and s2 equal? = "+s1.Equals(s2)); Console.WriteLine("Is s2 and s3 equal? = "+s2.Equals(s3)); Console.WriteLine("Is s3 and s4 equal? = "+s3.Equals(s4)); Console.WriteLine("Is s4 and s5 equal? = "+s4.Equals(s5)); Console.WriteLine(string.CompareOrdinal(s1, s2)); Console.WriteLine(string.CompareOrdinal(s2, s3)); Console.WriteLine(string.CompareOrdinal(s3, s4)); Console.WriteLine(string.CompareOrdinal(s4, s5)); } }
출력
String1 = David String2 = David String3 = David String4 = Tom String5 = Tom Is s1 and s2 equal? = True Is s2 and s3 equal? = True Is s3 and s4 equal? = False Is s4 and s5 equal? = True 0 0 -16 0
