Exception of System.Xml.XmlTextReader.Boolean Read()

I am so sorry for my unfinished question I have posted. I made mistake typing. I post my question again.

 

 

-----

 

When I create iControl application by using .NetFramework(C), sometimes the exception of System.Xml.XmlTextReader.Boolean Read() comes in API extension. The enviroment of this phenomenon is showed below. (This problem occurs so rarely.)

 

 

Generated API:

 

LocalLB.PoolMember.get_session_enabled_state

 

LocalLB.PoolMember.get_ratio

 

LocalLB.Pool.get_member

 

 

Example of argument: value of string[]

 

QA_TEST_POOL

 

P100

 

QA_TEST_POOL_Part2

 

TestPool999

 

 

Exception

 

classification: XmlException

 

message: The root element is missing.

 

 

If you have any idea about the reason for this phenomenon, please let me know.

 

Thank you.
