Can I Use Reserved Keywords as Variable Names in C#?

The role of @ symbol in variable name prefix in C#

The

@ symbol is usually used to modify the way string literals are parsed. However, it does much more than that. In C#, the @ symbol can also be placed in front of a variable name for specific purposes.

Add the @ symbol before the variable name to override certain language restrictions. A typical example is using reserved keywords as variable names. Reserved keywords in C# (such as "class") cannot be used directly as variable names without using additional syntax. However, the @ symbol solves the problem:

<code class="language-c#">int @class = 15;</code>

In this example, the @ symbol allows the variable to be named "class", which is normally not allowed because "class" is a reserved keyword.

The

@ symbol actually allows reserved words to be used as variable names. As shown in the above code, the @ prefix enables the variable "@class" to be assigned a value of 15. Without the @ symbol, the following code will cause a compiler error:

<code class="language-c#">int class = 15;</code>
