What is the difference between String.Copy() and String.Clone() methods in C#?
The String.Copy() method creates a new instance of String. This is same as the specified String.
The following is an example of Copy() method −
Example
using System;
class Demo {
static void Main(String[] args) {
string str1 = "mark";
string str2 = "marcus";
Console.WriteLine("str1 = '{0}'", str1);
Console.WriteLine("str2 = '{0}'", str2);
Console.WriteLine("After using String.Copy...");
str2 = String.Copy(str1);
Console.WriteLine("str1 = '{0}'", str1);
Console.WriteLine("str2 = '{0}'", str2);
}
}Output
str1 = 'mark' str2 = 'marcus' After using String.Copy... str1 = 'mark' str2 = 'mark'
The String.Clone() method returns a reference to the instance of String. The following is an example of Clone() method −
Example
using System;
class Demo {
static void Main(String[] args) {
string str1 = "amy";
string str2 = "emma";
Console.WriteLine("str1 = '{0}'", str1);
Console.WriteLine("str2 = '{0}'", str2);
Console.WriteLine("After using String.Clone...");
str2 = (String)str1.Clone();
Console.WriteLine("str1 = '{0}'", str1);
Console.WriteLine("str2 = '{0}'", str2);
}
}Output
str1 = 'amy' str2 = 'emma' After using String.Clone... str1 = 'amy' str2 = 'amy'
