Solution 1

Message is clear, the params you are passing to the save methods have something wrong. I suppose that you are trying to pass an List<> as a second parameter, meanwhile the method is expecting the array of SubjectInfo.

Try to call it in this way:

if (mStudentWS.save(mStudentInfo, mSubjectInfoList.ToArray()))

Cheers!
