Answer 1

The accepted answer by Jon Skeet is a good solution. However, you can write this with shorter code nowadays. It works the same:

public class TestPropertyAttribute : Attribute
{
    public TestPropertyAttribute(string name)
    {
        Name = name;
    }

    public string Name { get; }
}
