This blog post will explain 3 different use cases of the @ Symbol in C# and how the .NET developers can use them.
3 uses of the @ Symbol in C#
1. You can use one of the reserved words of c# with the this symbol
string @int = "senthil kumar";
or something like this
string @class ="MCA";
Although you can use this , avoid using one.
2. Before a string specially when using the file paths .
You can use
string filepath = @"D:\SENTHIL-DATA\myprofile.txt";
string filepath = "D:\\SENTHIL-DATA\\myprofile.txt";
3. For a Multi lined text
string ThreeIdiots = @"Senthil Kumar, Norton Stanley, and Pavan Rao!"; MessageBox.Show(ThreeIdiots);
string ThreeIdiots = @"Senthil Kumar,\n Norton Stanley,and Pavan Rao!";
You can run the above code snippets using the below Run Code Snippet button.
This is what the c# Language specification states about the @ Symbol
“The prefix “@” enables the use of keywords as identifiers, which is useful when interfacing with other programming languages. The character @ is not actually part of the identifier, so the identifier might be seen in other languages as a normal identifier, without the prefix. An identifier with an @ prefix is called a verbatim identifier. Use of the @ prefix for identifiers that are not keywords is permitted, but strongly discouraged as a matter of style.”
Interesting symbol isn’t it ??
