Beispiele
Im folgenden Codebeispiel wird die kontextbezogene Verwendung der EmitCalli -Methode veranschaulicht, um eine nicht verwaltete Typmethode außerhalb der dynamischen Klasse aufzurufen.
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 ...

Parameter
- callingConvention
- CallingConventions
Die zu verwendende verwaltete Aufrufkonvention.
- parameterTypes
- Type[]
Die Typen der für die Anweisung erforderlichen Argumente.
- optionalParameterTypes
- Type[]
Die Typen der optionalen Argumente für varargs

Wenn optionalParameterTypes
optionale Argumente angegeben werden, callingConvention
muss das CallingConventions.VarArgs Flag enthalten sein.
