Why PropertyInfo.GetValue() need the instance to retrieve the value?

The PropertyInfo class has the GetValue method which takes two parameters, the first one is the instance of the property.
Well it's just doesn't make sense to me, why the ProperyInfo doesn't hold the value? I get the PropertyInfo from the instance and then I need the Instance again to retrieve the value?!
That's weird.

Can someone please explain me why C# built that way?

The PropertyInfo class is designed on a per-type basis. The PropertyInfo resembles the property on the class, and not on the instance. That's why you need the instance to retrieve the value.

the propertyinfo generates from the instance only the construction plan and not the values itself

A PropertyInfo is "metadata"; it is associated with a property defined on a type, not an instance.
