法律探討C# 中 Equals(String, String) 方法
C# 中的 Equals() 方法用於檢查兩個 String 物件是否具有相同的值。
語法
bool string.Equals(string s1, string s2)
上述中，s1 和 s2 是要比較的字串。
示例
using System;
public class Demo {
public static void Main(string[] args) {
string s1 = "Kevin";
string s2 = "Tom";
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));
}
}輸出
String1 = Kevin String2 = Tom Are both the strings equal? = False Are both the strings equal? = True
示例
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));
}
}輸出
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
