How to use C# string Copy

By: Rajesh P.S.

The C# String Copy method assumes a significant role in the scope of string manipulation by facilitating the creation of a brand new String object that encapsulates an exact replica of the original string's content. This method serves as a powerful mechanism for duplicating the content of a string, allowing developers to work with a pristine copy while preserving the integrity of the original string.

When the Copy method is invoked, it initiates a careful process of recreating the string's content, resulting in the creation of a fresh String object. This newly generated object mirrors the content of the source string, ensuring an identical representation of characters and preserving any formatting or encoding intricacies associated with the original string.

string string.Copy(string str)

Parameters:

String str : The argument String for Copy method

Returns:

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

Exceptions:

System.ArgumentNullException : If the argument is null.

The Copy method empowers developers to work with a pristine and independent replica of the original string, allowing for diverse and nuanced data processing techniques. By utilizing this functionality, programmers can confidently experiment and apply modifications without worrying about unintended consequences on the source string.

Full Source C#

using System; using System.Windows.Forms; namespace WindowsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { string str1 = null; string str2 = null; str1 = "CSharp Copy() test"; str2 = string.Copy(str1); MessageBox.Show(str2); } } }

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

Conclusion

The C# String Copy method plays a vital role in string manipulation by enabling the creation of a new String object that faithfully replicates the content of the original string. This capability empowers developers to safely and efficiently operate on string data while preserving the integrity of the original content, contributing to the creation of robust and reliable software applications.
