Passing Arrays of Primitives to Methods

For an array, use the name of the parameter as the name of the property. For example, the
PerformanceManager.QueryPerfCounter
method requires an array of integers for the
counterId
parameter, as follows:
<counterId>58</counterId><counterId>65603</counterId><counterId>65604</counterId>
Even if you want to submit a single value for a single array element, you must wrap the parameter name around the value in this way.
