Przykłady

W poniższym przykładzie kodu pokazano, jak dołączyć metodę dynamiczną do właściwości utworzonej setPropertyBuilder za pomocą polecenia SetSetMethod.

TypeBuilder^ helloWorldTypeBuilder = myModule->DefineType( "HelloWorld", TypeAttributes::Public );

// Define a private String field named "m_greeting" in "HelloWorld" class.
FieldBuilder^ greetingFieldBuilder = helloWorldTypeBuilder->DefineField( "m_greeting", String::typeid, FieldAttributes::Private );

// Create constructor args and define constructor.
array<Type^>^constructorArgs = {String::typeid};
ConstructorBuilder^ constructor = helloWorldTypeBuilder->DefineConstructor( MethodAttributes::Public, CallingConventions::Standard, constructorArgs );

// Generate IL code for the method. The constructor stores its argument in the private field.

constructorIL->Emit( OpCodes::Ldarg_0 );
