| Title | resource name | ClassObject.tp_new can mask constructor exceptions |
| Description | resource summary | This: >>> from CLR.System.Drawing import Font >>> Font("Verdana", 0.0) raises a TypeError ("no constructor matches given arguments") even though there is a Font(String, Single) constructor overload. I believe the problem is in ClassObject.tp_new. It assumes that if the call to binder.InvokeRaw returns null, it means no matching overload was found. However, in the above case, the constructor raises an ArgumentException, which is then lost by the attempt to call the default constructor (since Font doesn't have a default constructor, it raises the TypeError). (Also, I note that the attempt to call the default constructor is passing in the kw parameter; if keywords are going to be supported in PythonNet method calls, it would probably be better to pass IntPtr.Zero). |
