Remarks

If you want to test for a specific OPC UA error, you will find the necessary information in the ServiceResult property. In most cases, you can use the fact that there is an implicit conversion from UAServiceResult to System.Int32, and make a comparison of the ServiceResult with some value from the UACodeBits class easily.
