AmbiguousMatchException uses the HRESULT COR_E_AMBIGUOUSMATCH which has the value 0x8000211D.

An AmbiguousMatchException is thrown if the application calls upon a class and it cannot determine which class or overloaded class to utilize. The binding attempts to locate the proper class to use, determined by the number of parameters and the type of parameters. If multiple acceptable classes are located, AmbiguousMatchException is thrown.

Overload resolution is a mechanism for selecting the best function member to invoke given an argument list and a set of candidate function members. Overload resolution selects the function member to invoke. If a selection cannot be determined, an AmbiguousMatchException is thrown.
