Avoid using magic
string use Nameof operator instead
There are several occasions when you will need to use “magic
string” within your code. Such “magic strings” are normal C# strings that map
to program elements within your code. For example, when raising
OnPropertyChanged event, you’d use a string for the name of the corresponding
property. Unfortunately, these magic strings had no compile time validation and
any program element changes (such as renaming property) wouldn’t automatically
update the magic string, resulting in an inconsistency that was never caught by
the compiler.
Extracting
the Property Name with a Nameof Expression
public string FirstName
{
get {
return _firstName; }
set {
_firstName = value; OnPropertyChanged(nameof(FirstName)); }
}
There are several other occasions where you can avoid the
writing magic string in you code.
