Marshal.GetObjectsForNativeVariants(T) Method (IntPtr, Int32)

[Supported in the .NET Framework 4.5.1 and later versions]

Converts an array of COM VARIANTs to an array of a specified type.

Namespace:  System.Runtime.InteropServices
Assembly:  mscorlib (in mscorlib.dll)

static member GetObjectsForNativeVariants : 
        aSrcNativeVariant:IntPtr * 
        cVars:int -> 'T[] 

Type Parameters

T

The type of the array to return.

Parameters

aSrcNativeVariant
Type: System.IntPtr

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

cVars
Type: System.Int32

The count of COM VARIANTs in aSrcNativeVariant.

Return Value

Type: T[]
An array of T objects that corresponds to aSrcNativeVariant.

ExceptionCondition
ArgumentOutOfRangeException

cVars is a negative number.

GetObjectsForNativeVariants(T)(IntPtr, Int32) returns an array of T that corresponds to a raw pointer to a C-style array of unmanaged VARIANT types. The interop marshaler 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.
