Name of a property as input to attribute constructor

I have a custom attribute and I would like it to have the name of a property as input. Because the name is a string it is a valid input type (as attributes are quite limited as to what they can have as input to their constructors). But how can I accomplish this?

Take this example code:

public class MyCustomAttribute : Attribute {
    public MyCustomAttribute(string propertyName) {}
}

public class Foo {
    public bool MyCustomProperty { get; set; }

    [MyCustom(SomeMagicAppliedToMyCustomProperty)] // I want the attribute to receive something along the lines of "Foo.MyCustomProperty"
    public void Bar();
}

How can I accomplish this with the limitations to what an attribute can receive in its constructor?

Solution

  • This is not possible. The attributes can accept only constants, just put your MyCustomProperty name in quotes into the Attribute.
