I am working on a project that declares html attributes as @class = "className" or @id = "ID" however for this form control it does not happen:
@Html.CheckBoxFor(Model => Model.IsEBSCreated, new { disabled = "disabled" })
Questions:
disabled not have an @ symbol before it?@ symbol not always required?checked require an @ symbol?Thank you
@ prefix on an identifier in C# allows language keywords to be used as identifiers, aka verbatim identifier.@ with C#'s contextual keywords like from and where - only C#'s reserved keywords.Why does the HTML attribute
disablednot have an@symbol before it?
Because disabled is not a C# language keyword.
Is the
@symbol not always required?
Only when you're using a C# language keyword as an identifier.
Does the HTML attribute
checkedrequire an@symbol?
Yes, because checked (and unchecked) are C# language keywords.
For example:
public interface @interface
{
string? @string { get; }
}
public class @class : @interface
{
private static readonly string? @null = null;
string? @interface.@string => @null;
}
Feel free to use the above code in a team project if you happen to dislike a particular member of your team.
@is used to escape names that would otherwise be C# language keywords (class,checked,bool,abstractetc).minstead ofModelinside HtmlHelper methods becauseModelis the same name asthis.Modelinside a View - name collisions should be avoided.iddoes not require an@But in the code it always has an@so I assume it doesn't break anything if its not necessary but present
