Issue when serializing custom collections with additional properties

[Karthik1979]

I have a custom class inherited from List<T> collection. Along with the base class functionality, I have included my additional properties. When serializing, only the base class items are serialized not my additional properties.

I have designed a business object collection like this and I have to pass it across the service layer. But in another end I’m getting partial data not all my information is getting de-serialized. Here is a sample scenario.

public class Student
{
int mRollno;
string mStudentName;

public string StudentName
{
get
{
return mStudentName;
}
set
{
mStudentName = value;
}
}

public int Rollno
{
get
{
return mRollno;
}
set
{
mRollno = value;
}
}
}


public class Students : List<Student>
{
string mSchoolName;

public string SchoolName
{
get
{
return mSchoolName;
}
set
{
mSchoolName = value;
}
}
}

If I serialize this “Students” collection, I’m getting following XML, but it is missing the additional property SchoolName of Students.

<?xml version="1.0"?>
<ArrayOfStude nt xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http ://www.w3.org/2001/XMLSchema">
<Student>
<StudentName>On e</StudentName>
<Rollno>1</Rollno>
</Student>
<Student>
<StudentName>Tw o</StudentName>
<Rollno>2</Rollno>
</Student>
<Student>
<StudentName>Th ree</StudentName>
<Rollno>3</Rollno>
</Student>
</ArrayOfStudent>

Please guide me what I’m missing here. Thanks in advance.

I have solved this by implementing IXMLSerialize interface.
