Property Value

If set to Error, supplying a non-multi-value argument more than once will cause an exception. If set to Allow, the last value supplied will be used.

If set to Warning, the ParseWithErrorHandling method, the static ParseT(ParseOptions) method and the CommandManager class will print a warning to the Error stream when a duplicate argument is found. If you are not using these methods, Warning is identical to Allow and no warning is displayed.

If not , this property overrides the value of the DuplicateArguments property.
