Missing support for ref- and out args for sync calls #4
Description
Activity
[DispatchProxyAsync] is have a bag - the author incorrectly added the processing of out and ref parameters.
Copying the parameters back occurs before calling the invoke method.
Fix: move block in row 682
for (int i = 0; i < parameters.Length; i++)
{
if (parameters[i].ParameterType.IsByRef)
{
args.BeginSet(i);
argsArr.Get(i);
args.EndSet(i, typeof(object));
}
}
after row 707 il.Emit(OpCodes.Callvirt, invokeMethod);
is now work fine
There is also a bug with out parameters: out parameter values are not passed to invoke
comment row 627 if (!parameters[i].IsOut)
Async calls don't support
ref- oroutarguments but synchronous calls do. But this doesn't work in DispatchProxyAsync.When calling via
Invoke, those arg types should be supported but I get an exception. The original DispatchProxy does support it.See my example on dotnetfiddle.
Also try only out- args or only ref-args.
