Contoh

Sampel kode mengilustrasikan penggunaan GetParameters.

// Define a constructor of the dynamic class.
ConstructorBuilder^ myConstructorBuilder = myTypeBuilder->DefineConstructor(
   MethodAttributes::Public, CallingConventions::Standard, myConstructorArgs );
// Get a reference to the module that contains this constructor.
Module^ myModule = myConstructorBuilder->GetModule();
Console::WriteLine( "Module Name : {0}", myModule->Name );
// Get the 'MethodToken' that represents the token for this constructor.
MethodToken myMethodToken = myConstructorBuilder->GetToken();
Console::WriteLine( "Constructor Token is : {0}", myMethodToken.Token );
// Get the method implementation flags for this constructor.
MethodImplAttributes myMethodImplAttributes = myConstructorBuilder->GetMethodImplementationFlags();
Console::WriteLine( "MethodImplAttributes : {0}", myMethodImplAttributes );
// Generate IL for the method, call its base class constructor and store the arguments
// in the private field.
ILGenerator^ myILGenerator3 = myConstructorBuilder->GetILGenerator();
myILGenerator3->Emit( OpCodes::Ldarg_0 );

Keterangan

Properti ini tidak didukung sampai setelah TypeBuilder.CreateType metode dipanggil. Dalam versi .NET Framework 1.0 dan 1.1, InvalidOperationException dilemparkan. Dalam .NET Framework versi 2.0, NotSupportedException dilemparkan.
