Get resource property values from the server.
FindProperties will request the values for the names at each item provided in the Properties collection. The matching URIs and property values will be returned through one or more ResourceProperties events (one for each matching resource).
Depth is used to determine which resources or properties are retrieved from the server. A depth of ResourceOnly will return only the resource associated with ResourceURI, or its properties. A depth of Infinity will return all resources contained within hierarchy, or their collective properties.
Note: Some servers (such as IIS 7.5) may not support a depth of Infinity by default and may return a HTTP 403 Forbidden response.
