C＃nameof运算符引用实例属性可以没有实例吗？

Question

I regularly want to get the name of an instance property of a type, when I have no instance. Currently to do this, I use the following inhouse function which interprets the Expression[Func[T, object]] parameter and returns the property name:

var str = LinqExtensions.NameOf<ClientService>(x => x.EndDate);
// Now str == "EndDate"

However it seems a shame not to use the built in nameof operator.

Unfortunately it seems that the nameof operator requires either an instance, or, to reference a static properties.

Is there a neat way to use the nameof operator instead of our in house function? For example:

nameof(ClientService.EndDate) // ClientService.EndDate not normally syntactically valid as EndDate is instance member

EDIT

I was completely wrong, the syntax nameof(ClientService.EndDate) as described actually works as is.

Answer 1

From the documentation :

In the examples you see that you can use a type name and access an instance method name. You do not need to have an instance of the type … [emphasis mine]

Ie you should be able to write nameof(ClientService.EndDate) and have it work, contrary to your statement in the question that this would be "not normally syntactically valid" .

If you are having trouble with the syntax, please provide a good Minimal, Complete, and Verifiable code example that reliably reproduces whatever error you're getting, and provide the exact text of the error message.

Great answer by @Peter Duniho.

In case of name clashes, you can also do the following:

ClientService clientservice;
var str = nameof(clientservice.EndDate);

Not efficient, but curious enough.
