![]() ![]() But, there are circumstances when we want a runtime access to all packages in the module even if an explicit export statement is not declared. This is exactly what we want when we like to use the functionality of a module. If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the methods of the class constraint, or the methods of Object if there is no class constraint.The packages in a module are accessible if explicit export statements are stated in the module definition file. If the current Type represents a constructed generic type, this method returns the MethodInfo objects with the type parameters replaced by the appropriate type arguments. BindingFlags.DeclaredOnly to search only the methods declared on the Type, not methods that were simply inherited.The following BindingFlags modifier flags can be used to change how the search works: Specify BindingFlags.Default alone to return an empty MethodInfo array. Specify BindingFlags.FlattenHierarchy to include public and protected static members up the hierarchy private static members in inherited classes are not included. Only protected and internal methods on base classes are returned private methods on base classes are not returned. Specify BindingFlags.NonPublic to include non-public methods (that is, private, internal, and protected methods) in the search. Specify BindingFlags.Public to include public methods in the search. Specify BindingFlags.Static to include static methods. Specify BindingFlags.Instance to include instance methods. The following BindingFlags filter flags can be used to define which methods to include in the search: Public Shared Sub DisplayMethodInfo(ByVal myArrayMethodInfo() As MethodInfo)įor i = 0 To myArrayMethodInfo.Length - 1ĭim myMethodInfo As MethodInfo = CType(myArrayMethodInfo(i), MethodInfo)Ĭonsole.WriteLine((ControlChars.Cr + "The name of the method is " & myMethodInfo.Name & "."))įor the GetMethods(BindingFlags) overload to successfully retrieve method information, the bindingAttr argument must include at least one of BindingFlags.Instance and BindingFlags.Static, along with at least one of BindingFlags.NonPublic and BindingFlags.Public. Protected Function MyMethods2() As ĭim myType As Type = GetType(MyTypeClass)ĭim myArrayMethodInfo As MethodInfo() = myType.GetMethods((BindingFlags.Public Or BindingFlags.Instance Or BindingFlags.DeclaredOnly))Ĭonsole.WriteLine((ControlChars.Cr + "The number of public methods is " & () & "."))ĭim myArrayMethodInfo1 As MethodInfo() = myType.GetMethods((BindingFlags.NonPublic Or BindingFlags.Instance Or BindingFlags.DeclaredOnly))Ĭonsole.WriteLine((ControlChars.Cr + "The number of protected methods is " & () & ".")) ' Create a class having two public methods and one protected method. MethodInfo^ myMethodInfo = dynamic_cast(myArrayMethodInfo) Ĭonsole::WriteLine( "\nThe name of the method is. Void DisplayMethodInfo( array^myArrayMethodInfo ) Create a class having two public methods and one protected method. Using namespace System::Reflection::Emit The following example creates a class with two public methods and one protected method, creates a Type object corresponding to MyTypeClass, gets all public and non-public methods, and displays their names. GetMethods(BindingFlags) GetMethods(BindingFlags) Examples If you have a property with both a get and a set accessor in the base class, but the derived class has only a get accessor, the derived class property hides the base class property, and you will not be able to access the setter on the base class.Ĭustom attributes are not part of the common type system. This is a binary comparison.įor reflection, properties and events are hide-by-name-and-signature. Hide-by-name-and-signature considers all of the parts of the signature, including custom modifiers, return types, parameter types, sentinels, and unmanaged calling conventions. A method (both virtual and non-virtual) can be hide-by-name or hide-by-name-and-signature. Reflection treats properties as hide-by-name-and-signature. The common type system rule is that the inheritance is the same as that of the methods that implement the property. A field is always hide-by-name-and-signature. The following table shows what members of a base class are returned by the Get methods when reflecting on a type. Make a separate call to GetConstructors() to get the constructor methods. Your code must not depend on the order in which methods are returned, because that order varies.Ĭonstructors are not included in the array of methods returned by this call. The GetMethods method does not return methods in a particular order, such as alphabetical or declaration order.
