public final class SafeArrayDefaultRankAttribute extends Attribute
Remarks
For a host application that is based on COM, add the SafeArrayDefaultRank attribute in the proxy code to marshaled safe array parameters or return values to specify the actual rank of the arrays in question. This is needed because there is no differentiation between one-dimensional and multi-dimensional arrays in the COM type library. The COM safe arrays are converted to one-dimensional arrays in the proxy code by default. Also, use the SafeArrayDefaultRank attribute with parameters or return values of type System.Array or System.Object[] that do not convey rank information.
