Remarks
The ParamArrayAttribute indicates that a method parameter is a parameter array. A parameter array allows the specification of an unknown number of arguments. A parameter array must be the last parameter in a formal parameter list, and it must be a single-dimension array. When the method is called, a parameter array permits arguments to a method to be specified in either of two ways:
As a single expression of a type that is implicitly convertible to the parameter array type. The parameter array functions as a value parameter.
As zero or more arguments, where each argument is an expression of a type that is implictly convertible to the type of the parameter array element.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
