Definisi

Ruang nama:

System.Reflection.Emit

Rakitan:

System.Reflection.Emit.dll

Sumber:

PropertyBuilder.cs

Mengatur metode yang mengatur nilai properti.

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)

Parameter

mdBuilder

MethodBuilder

Objek MethodBuilder yang mewakili metode yang mengatur nilai properti.

Pengecualian

ArgumentNullException

mdBuilderadalah null.

InvalidOperationException

CreateType() telah dipanggil pada jenis penutup.

Contoh

Sampel kode berikut menunjukkan cara melampirkan metode dinamis ke properti yang set dibuat dengan PropertyBuilder menggunakan 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.

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