The types that should be used when passing the input arguments to the server.
Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

Element positions in this property correspond to argument positions in InputArguments.

A null value in this property, a null value in specific element, or a missing element (when there is fewer types than arguments) means that the input argument will be passed to the server without change.

The getter method of this property is pure, i.e. it does not have observable side effects.

This member is not compatible with Visual Basic 6.0 (VB6).

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.
