C# Copy() Method

The Copy() method in C# is used to create a new instance of String with the same value as a specified String.

Syntax

public static string Copy (string s);

Above, s is the string to copy.

Example

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));
   }
}

Output

String1 = Amy
String2 = Katie
Are both the strings equal? = False
Are both the strings equal? = True
-10
0

Example

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));
   }
}

Output

String1 = Gary
String2 = Gary
Is s1 and s2 equal? = True
Is s2 and s3 equal? = True
Is s2 and s3 equal? = False
