দুটি স্ট্রিং অবজেক্টের মান একই আছে কি না তা পরীক্ষা করতে C# এ Equals() পদ্ধতি ব্যবহার করা হয়।
সিনট্যাক্স
bool string.Equals(string s1, string s2)
উপরে, s1 এবং s2 তুলনা করা স্ট্রিং।
উদাহরণ
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));
}
} আউটপুট
String1 = Kevin String2 = Tom Are both the strings equal? = False Are both the strings equal? = True
উদাহরণ
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("Is s4 and s5 equal? = "+s4.Equals(s5));
}
} আউটপুট
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
