	cVars As Integer
) As T()


Type: System.IntPtr

A pointer to the first element of an array of COM VARIANTs.

Type: System.Int32

Return Value

Exception Condition

cVars is a negative number.

GetObjectsForNativeVariants(Of T)(IntPtr, Int32) returns an array of T that corresponds to a raw pointer to a C-style array of unmanaged VARIANT types. The interopmarshaler performs the identical transformation when exposing a VARIANT type to managed code. The method returns an empty array when the cVars parameter is 0.

The returned array is garbage-collected as usual. The unmanaged input array or individual VARIANTs in the input array are not freed. Therefore, it is your responsibility to free them as appropriate.


requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
