WebA non-static method requires an instance of the class. Unless you have passed in an instance, or created an instance in your method, you cannot call a non-static method, as you have no idea what instance of the class that method should operate on. You need an instance of the class class to call the non-static method. Share Improve this answer WebC# has a static class syntax (not to be confused with static inner classes in Java), which restricts a class to only contain static methods. C# 3.0 introduces extension methods to allow users to statically add a method to a type (e.g., allowing foo.bar() where bar() can be an imported extension method working on the type of foo).
WebFeb 15, 2010 · A non-static class with static members usually indicates that the class is designed to be instantiated at some point. Static methods of these classes usually do one of two things: Provide a factory method for creating an instance of that type; Provide helper functionality that does not require an instance of the type; WebNov 10, 2010 · No you can't. The reason for the limitation is that static methods can also be called from non-static contexts without needing to prepend the class name (so MyStaticMethod () instead of MyClass.MyStaticMethod ()). The compiler can't tell which you're looking for if you have both.

An interface is a contract for instances. I would recommend creating the interface as you are currently, but without the static keyword. Then create a class StaticIInterface that implements the interface and calls the static C++ methods.
WebNov 30, 2011 · The refactoring from non-static to static is relatively easy (just add a keyword), so if you want to make a can-be-static into an actual static later (when you need it's functionality outside of an instance) then you can. However, the inverse refactoring, turning a can-be-static into a instance method is MUCH more expensive.

Emitting non-virtual call sites will prevent a check at runtime for each call that ensures that the current object pointer is non-null.
