How do I access the Measurement array of a MultipleNumericLimitTest?

[tlaford]

Here is a Csharp code snippet that I thought should work, but doesn't:

...
    PropertyObject item;
...
    if (item.GetValString("TS.StepType", 0) == "NI_MultipleNumericLimitTest")
    {
        string lowerBound, upperBound;
        int numElements;
        PropertyValueTypes elementType;
        item.GetDimensions("Measurement", 0, out lowerBound, out upperBound, out numElements, out elementType);

        for (int k = 0; k < numElements; ++k)
        {
            // **** This next line throws an exception - "Specified value does not have expected type"
            PropertyObject arrayEntry = (PropertyObject)item.GetValVariantByOffset(k, 0);

            if (arrayEntry.Exists("Status", 0))
            {
                this.currentResultData.status = arrayEntry.GetValString("Status", 0);
            }
            ...
        }
    }

Can someone enlighten me as to what I should be doing to properly access the Measurement Array?

I figured it out...

     item.GetDimensions("Measurement", 0, out lowerBound, out upperBound, out numElements, out elementType);
     ...
     PropertyObject arrayEntry = (PropertyObject)item.GetValVariantByOffset(k, 0);

... should be ...

    PropertyObject measurementProperty = item.GetPropertyObject("Measurement", 0);
    measurementProperty.GetDimensions("", 0, out lowerBound, out upperBound, out numElements, out elementType);
    ...
    PropertyObject arrayEntry = (PropertyObject)measurementProperty.GetValVariantByOffset(k, 0);

It's probably better to call GetPropertyObjectByOffset instead of GetValVariantByOffset, then you won't need the cast and will give a better error message if it's not an array of objects.
