PropertyBuilder::SetSetMethod Method (MethodBuilder^)

 

Sets the method that sets the property value.

Namespace:   System.Reflection.Emit
Assembly:  mscorlib (in mscorlib.dll)

public:
void SetSetMethod(
	MethodBuilder^ mdBuilder
)

Parameters

mdBuilder
Type: System.Reflection.Emit::MethodBuilder^

A MethodBuilder object that represents the method that sets the property value.

Exception Condition
ArgumentNullException

mdBuilder is null.

InvalidOperationException

CreateType has been called on the enclosing type.

The following code sample demonstrates how to attach a dynamic method to a set property created with PropertyBuilder using 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 );
methodIL->Emit( OpCodes::Ldfld, greetingFieldBuilder );
methodIL->Emit( OpCodes::Ret );
greetingPropertyBuilder->SetGetMethod( getGreetingMethod );


// Define the set_Greeting method.
array<Type^>^methodArgs = {String::typeid};
MethodBuilder^ setGreetingMethod = helloWorldTypeBuilder->DefineMethod( "set_Greeting", static_cast<MethodAttributes>(MethodAttributes::Public | MethodAttributes::HideBySig | MethodAttributes::SpecialName), void::typeid, methodArgs );

// Generate IL code for set_Greeting method.
methodIL = setGreetingMethod->GetILGenerator();
methodIL->Emit( OpCodes::Ldarg_0 );
methodIL->Emit( OpCodes::Ldarg_1 );
methodIL->Emit( OpCodes::Stfld, greetingFieldBuilder );
methodIL->Emit( OpCodes::Ret );
greetingPropertyBuilder->SetSetMethod( setGreetingMethod );
