Sets the method that sets the property value.
public:
void SetSetMethod(System::Reflection::Emit::MethodBuilder ^ mdBuilder);
public void SetSetMethod (System.Reflection.Emit.MethodBuilder mdBuilder);
member this.SetSetMethod : System.Reflection.Emit.MethodBuilder -> unit
Public Sub SetSetMethod (mdBuilder As MethodBuilder)
Parameters
- mdBuilder
- MethodBuilder
A MethodBuilder
object that represents the method that sets the property value.
Exceptions
mdBuilder
is null
.
CreateType() has been called on the enclosing type.
Examples
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.
