Remarks

For a host application that is based on COM, add the SafeArrayDefaultRankAttribute 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 SafeArrayDefaultRankAttribute attribute with parameters or return values of type Array or System.Object[] that do not convey rank information.
