Remarks
The value of the Type property on a Property object, when it comes from a Properties collection on a Device, DeviceInfo, Filter, or Item object, can return one of the members of the WiaPropertyType enumeration. This gives more information about the type of value contained in the Value property.
For example code, see Display all the Properties for the Selected Device in Shared Samples.
