ParamArray (Visual Basic)
Specifies that a procedure parameter takes an optional array of elements of the specified type. ParamArray can be used only on the last parameter of a parameter list.
Remarks
ParamArray allows you to pass an arbitrary number of arguments to the procedure. A ParamArray parameter is always declared using ByVal (Visual Basic).
You can supply one or more arguments to a ParamArray parameter by passing an array of the appropriate data type, a comma-separated list of values, or nothing at all. For details, see "Calling a ParamArray" in Parameter Arrays (Visual Basic).

Whenever you deal with an array which can be indefinitely large, there is a risk of overrunning some internal capacity of your application. If you accept a parameter array from the calling code, you should test its length and take appropriate steps if it is too large for your application. |
