Hello everyone, This is probably a total n00b question, but I've been using pythonnet in our toolchain to communicate with a private c# assembly for months now without ever running into a problem I couldn't eventually figure out. This one has me totally stumped, and I'm hoping something obvious will jump out at experienced eyes.
(I did a find/replace for secrecy, besides silly names these are the raw results I get back) A C# class exposes a method 'WriteByte' that has 5 overloads (note that only one of them takes 2 arguments): >>> accessor= MyCompany.SomeNamespace.SomeTypeArrayAccessor >>> accessor.WriteByte.__overloads__ Boolean WriteByte(MyCompany.SomeNamespace.SomeType, Byte[]) Boolean WriteByte(MyCompany.SomeNamespace.SomeType, Byte[], Int32 ByRef) Boolean WriteByte(MyCompany.SomeNamespace.SomeType, System.Collections.Generic.IEnumerable`1[System.Byte], Int32 ByRef) Boolean WriteByte(MyCompany.SomeNamespace.SomeType, Int32, System.Collections.Generic.IEnumerable`1[System.Byte], Int32 ByRef) Boolean WriteByte(MyCompany.SomeNamespace.SomeType, Int32, Byte[], Int32 ByRef) I attempt to disambiguate by selecting the 2-arg method I want by type: >>> desired_method= >>> accessor.WriteByte.__overloads__[MyCompany.SomeNamespace.SomeType, >>> System.Array[System.Byte]] The problem may be right here - if I print out desired_method.__doc__ I get the same 5 methods listed above. Anyway, then I compute my arguments, and can verify they have the types I expect (If it matters, arg_b is created by a call to System.IO.BinaryReader.ReadBytes()): >>> arg_a= ... >>> arg_b= ... >>> type(arg_a) <class 'MyCompany.SomeNamespace.SomeType'> >>> type(arg_b) <class 'System.Byte[]'> However, when I try to call the disambiguated method with the correct args, I get no love: >>> result= desired_method(arg_a, arg_b) Traceback (most recent call last): File "<string>", line 1, in <fragment> TypeError: No method matches given arguments Does anyone see the obvious thing I'm doing wrong? Disambiguating can be a pain but I've done it before for other methods and have never had such an impossible time getting the correct method called.
