The private method CanConvertFrom finds compatible types for a given type. The following example demonstrates all members of the class using an overload of Type.InvokeMember. That is, the ContainsGenericParameters property returns true for the declaring type. The type that declares the method is an open generic type. public:Ībstract System::Object ^ Invoke(System::Object ^ obj, System::Reflection::BindingFlags invokeAttr, System::Reflection::Binder ^ binder, cli::array ^ parameters, System::Globalization::CultureInfo ^ culture) public abstract object? Invoke (object? obj, invokeAttr, ? binder, object? parameters, ? culture) public abstract object Invoke (object obj, invokeAttr, binder, object parameters, culture) abstract member Invoke : obj * * * obj * -> obj Public MustOverride Function Invoke (obj As Object, invokeAttr As BindingFlags, binder As Binder, parameters As Object(), culture As CultureInfo) As Object Parameters When overridden in a derived class, invokes the reflected method or constructor with the given parameters. To invoke a static method using its MethodInfo object, pass null for obj. If the invoked method throws an exception, the Exception.GetBaseException method returns the originating exception. This is a convenience method that calls the Invoke(Object, BindingFlags, Binder, Object, CultureInfo) method overload, passing Default for invokeAttr and null for binder and culture. ' The example program gives the following output: Object^ magicValue = magicMethod->Invoke(magicClassObject, gcnew array(1)", magicValue) MethodInfo^ magicMethod = magicType->GetMethod("ItsMagic") Get the ItsMagic method and invoke with a parameter value of 100 Object^ magicClassObject = magicConstructor->Invoke(gcnew array(0)) Type^ magicType = Type::GetType("MagicClass") ĬonstructorInfo^ magicConstructor = magicType->GetConstructor(Type::EmptyTypes) Get the constructor and create an instance of MagicClass Note that you cannot use the MethodInfo object from the base class to invoke the overridden method in the derived class, because late binding cannot resolve overrides.
