InvalidOperationException

Se ha llamado a CreateType() en el tipo envolvente.

Ejemplos

En el ejemplo de código siguiente se muestra cómo adjuntar un método dinámico a una set propiedad creada con PropertyBuilder mediante 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.
ILGenerator^ constructorIL = constructor->GetILGenerator();
constructorIL->Emit( OpCodes::Ldarg_0 );
constructorIL->Emit( OpCodes::Ldarg_1 );
constructorIL->Emit( OpCodes::Stfld, greetingFieldBuilder );
constructorIL->Emit( OpCodes::Ret );

// Define property Greeting.
PropertyBuilder^ greetingPropertyBuilder = helloWorldTypeBuilder->DefineProperty( "Greeting", PropertyAttributes::None, String::typeid, nullptr );

// Define the 'get_Greeting' method.
MethodBuilder^ getGreetingMethod = helloWorldTypeBuilder->DefineMethod( "get_Greeting", static_cast<MethodAttributes>(MethodAttributes::Public | MethodAttributes::HideBySig | MethodAttributes::SpecialName), String::typeid, nullptr );

// Generate IL code for 'get_Greeting' method.
ILGenerator^ methodIL = getGreetingMethod->GetILGenerator();
methodIL->Emit( OpCodes::Ldarg_0 );
