How to use C# string Copy

CSharp String Copy method creates a new String object with the same content.

string string.Copy(string str);


  • String str: The argument String for Copy method


  • String: Returns a new String as the same content of argument String


  • System.ArgumentNullException: If the argument is null.
using System;
using System.Windows.Forms;

namespace WindowsApplication1
	public partial class Form1 : Form
		public Form1()

		private void button1_Click(object sender, EventArgs e)
			string str1 = null;
			string str2 = null;

			str1 = "CSharp Copy() test";
			str2 = string.Copy(str1);


When you run this C# source code, you will get the same content of str1 in str2.
