Przykłady

W poniższym przykładzie pokazano, jak uzyskać obiekt RuntimeTypeHandle z typu lub z obiektu oraz jak przekształcić uchwyt z powrotem w typ.

using namespace System;
using namespace System::Reflection;

public ref class MyClass1
{
private:
    int x;

public:
    int MyMethod()
    {
        return x;
    }
};

int main()
{
    MyClass1^ myClass1 = gcnew MyClass1;
   
    // Get the RuntimeTypeHandle from an object.
    RuntimeTypeHandle myRTHFromObject = Type::GetTypeHandle( myClass1 );
   
    // Get the RuntimeTypeHandle from a type.
    RuntimeTypeHandle myRTHFromType = MyClass1::typeid->TypeHandle;

    Console::WriteLine( "\nmyRTHFromObject.Value:  {0}", myRTHFromObject.Value );
    Console::WriteLine( "myRTHFromObject.GetType():  {0}", myRTHFromObject.GetType() );
    Console::WriteLine( "Get the type back from the handle..." );
    Console::WriteLine( "Type::GetTypeFromHandle(myRTHFromObject):  {0}", 
        Type::GetTypeFromHandle(myRTHFromObject) );

    Console::WriteLine( "\nmyRTHFromObject.Equals(myRTHFromType):  {0}", 
        myRTHFromObject.Equals(myRTHFromType) );

    Console::WriteLine( "\nmyRTHFromType.Value:  {0}", myRTHFromType.Value );
    Console::WriteLine( "myRTHFromType.GetType():  {0}", myRTHFromType.GetType() );

Właściwości

Value

Pobiera dojście do typu reprezentowanego przez to wystąpienie.

Metody

Equals(Object)	Wskazuje, czy określony obiekt jest równy bieżącej RuntimeTypeHandle strukturze.
Equals(RuntimeTypeHandle)	Wskazuje, czy określona RuntimeTypeHandle struktura jest równa bieżącej RuntimeTypeHandle strukturze.
FromIntPtr(IntPtr)	Zwraca nowy RuntimeTypeHandle obiekt utworzony na podstawie uchwytu do typu runtimeType.
GetHashCode()	Zwraca kod skrótu dla bieżącego wystąpienia.
GetModuleHandle()	Pobiera dojście do modułu zawierającego typ reprezentowany przez bieżące wystąpienie.
GetObjectData(SerializationInfo, StreamingContext)	Wypełnia obiekt SerializationInfo danymi niezbędnymi do deserializacji typu reprezentowanego przez bieżące wystąpienie.
ToIntPtr(RuntimeTypeHandle)	Zwraca wewnętrzną reprezentację RuntimeTypeHandle wskaźnika obiektu.

Operatory

Equality(Object, RuntimeTypeHandle)	Wskazuje, czy obiekt i RuntimeTypeHandle struktura są równe.
Equality(RuntimeTypeHandle, Object)	Wskazuje, czy RuntimeTypeHandle struktura jest równa obiektowi.
Inequality(Object, RuntimeTypeHandle)	Wskazuje, czy obiekt i RuntimeTypeHandle struktura nie są równe.
Inequality(RuntimeTypeHandle, Object)	Wskazuje, czy RuntimeTypeHandle struktura nie jest równa obiektowi.
