XML Serialization Error of Collection

[Craig Schneider]

// Can anyone explain the bizarre XML Serialization behavior seen in
the following code.
// It seems that a collection can not be XML Serialized if it contains
an Add() method
// with a single parameter where that parameter is of a type in the
System.Data namespace
// (or a class derived from something in the System.Data namespace).
// Is there any way to prevent this from blowing up?

using System;
using System.Data;
using System.Collecti ons;
using System.IO;
using System.Xml.Seri alization;

namespace XMLStub
{
/// <summary>A simple class that holds a collection of
ints.</summary>
public class IntCollection : CollectionBase
{
public int this[int Index]
{
get { return((int)Lis t[Index]); }
}

public void Add(int NewInt)
{
List.Add(NewInt );
}

public void Add(string XXX) { } // Can be
serialized
public void Add(Type XXX) { } // Can be
serialized
public void Add(IntCollecti on XXX) { } // Can be
serialized
public void Add(DataColumn XXX, bool XXXBool) { } // Can be
serialized
// Simply uncommenting any of these methods causes the
XMLSerializatio n to fail
// public void Add(DataColumn XXX) { } // Throws when
serializing
// public void Add(DataTable XXX) { } // Throws when
serializing
// public void Add(DataSet XXX) { } // Throws when
serializing
// public void Add(Constraint XXX) { } // Throws when
serializing
// public void Add(VersionNotF oundException XXX) { } // Throws when
serializing

I tested your code and also found the problem. After checking the
documents, I found there is similair bug reported for XmlSerializer. This
behavior also can be found in VS.NET 2003. The temporary work arround is to
add one more parameter to the function, such as:

public void Add(DataColumn XXX,int i)

Do you have any more details on the bug. Such as the ID, or where I can
go to look at its status. Thanks!!!

There is several bugs which is very similar to this issue, for example,
when serializing in a web service. Currently I am researching to see if
their root cause are same.
