Przykłady
W poniższym przykładzie kodu pokazano kontekstowe użycie EmitCalli metody w celu wywołania metody typu niezarządzanego poza klasą dynamiczną.
MethodBuilder^ myMthdBuilder = myTypeBuilder->DefineMethod( "MyMethod",
MethodAttributes::Public,
returnType, mthdParamTypes );
// We will assume that an external unmanaged type "LegacyNumber" has been loaded, and
// that it has a method "ToString" which returns a String.
MethodInfo^ unmanagedMthdMI = Type::GetType( "LegacyNumber" )->GetMethod( "ToString" );
ILGenerator^ myMthdIL = myMthdBuilder->GetILGenerator();
// Code to emit various IL opcodes here ...
// Load a reference to the specific Object instance onto the stack.
myMthdIL->Emit( OpCodes::Ldc_I4, addrOfLegacyNumberObject );
myMthdIL->Emit( OpCodes::Ldobj, Type::GetType( "LegacyNumber" ) );
// Make the call to the unmanaged type method, telling it that the method is
// the member of a specific instance, to expect a String
// as a return value, and that there are no explicit parameters.
myMthdIL->EmitCalli( OpCodes::Calli,
System::Runtime::InteropServices::CallingConvention::ThisCall,
String::typeid,
gcnew array<Type^>( 0 ) );
// More IL code emission here ...
MethodBuilder myMthdBuilder = myTypeBuilder.DefineMethod("MyMethod",
MethodAttributes.Public,
returnType, mthdParamTypes);
// We will assume that an external unmanaged type "LegacyNumber" has been loaded, and
// that it has a method "ToString" which returns a string.
MethodInfo unmanagedMthdMI = Type.GetType("LegacyNumber").GetMethod("ToString");
ILGenerator myMthdIL = myMthdBuilder.GetILGenerator();
// Code to emit various IL opcodes here ...
// Load a reference to the specific object instance onto the stack.
myMthdIL.Emit(OpCodes.Ldc_I4, addrOfLegacyNumberObject);
myMthdIL.Emit(OpCodes.Ldobj, Type.GetType("LegacyNumber"));
// Make the call to the unmanaged type method, telling it that the method is
// the member of a specific instance, to expect a string
// as a return value, and that there are no explicit parameters.
myMthdIL.EmitCalli(OpCodes.Calli,
System.Runtime.InteropServices.CallingConvention.ThisCall,
typeof(string),
new Type[] {});
// More IL code emission here ...

Parametry
- callingConvention
- CallingConventions
Zarządzana konwencja wywoływania, która ma być używana.
- parameterTypes
- Type[]
Typy wymaganych argumentów instrukcji.
- optionalParameterTypes
- Type[]
Typy opcjonalnych argumentów dla varargs
wywołań.
Wyjątki
optionalParameterTypes
to nie null
, ale callingConvention
nie zawiera flagi VarArgs .
Uwagi
Użyj EmitCalli polecenia , aby umieścić instrukcję Calli na strumieniu. Nie używaj polecenia Emit.
Jeśli optionalParameterTypes
określa opcjonalne argumenty, callingConvention
musi zawierać flagę CallingConventions.VarArgs .
