Dmitry,

It might be a good idea if you could tell us what you plan to do with this class. The reason I say that is because, since you're new to .NET, you may or may not "get" the point of using static methods/properties.

As Gregory's example with the Person class pointed out, you wouldn't want to use Birthdate as a static property because that would be different in every instance of the Person class. If it wasn't obvious from his explanation, I just wanted to clarify that when you use static properties they will contain exactly the same values in every instance of the class. If you have several instances of the class, and in one instance you decide to make a change to a static property, then all the other instances of that class will automagically have that new value. If this is the kind of thing you want, then all is good.

Now, I know your specific question was about a static method, not property, but depending on what your method does it may need to use static properties ... so it may still be relevant to your question
