Remarks

MethodBase is the base class of MethodInfo and ConstructorInfo.

Notes to Implementers

When you inherit from MethodBase, you must override the following members: GetParameters(), Invoke(Object, BindingFlags, Binder, Object[], CultureInfo), GetMethodImplementationFlags(), MethodHandle, Attributes, Name, DeclaringType, MemberType, ReflectedType, GetCustomAttributes(Boolean), GetCustomAttributes(Type, Boolean), and IsDefined(Type, Boolean).

Constructors

MethodBase()

Initializes a new instance of the MethodBase class.

Gets a value indicating whether the method is abstract.
