C# Copy() 方法
C# 中的 Copy() 方法用于创建一个新 String 实例,该实例的值与指定的 String 相同。
语法
public static string Copy (string s);
上面,s 是要复制的字符串。
示例
using System; public class Demo { public static void Main(string[] args) { string s1 = "Amy"; string s2 = "Katie"; string s3 = String.Copy(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)); } }
输出
String1 = Amy String2 = Katie Are both the strings equal? = False Are both the strings equal? = True -10 0
示例
using System; public class Demo { public static void Main(string[] args) { string s1 = "Gary"; string s2 = "Gary"; string s3 = String.Copy(s2); Console.WriteLine("String1 = "+s1); Console.WriteLine("String2 = "+s2); Console.WriteLine("Is s1 and s2 equal? = "+s1.Equals(s2)); Console.WriteLine("Is s2 and s3 equal? = "+s2.Equals(s3)); s3 = "Harry"; Console.WriteLine("Is s2 and s3 equal? = "+s2.Equals(s3)); } }
输出
String1 = Gary String2 = Gary Is s1 and s2 equal? = True Is s2 and s3 equal? = True Is s2 and s3 equal? = False
