RE: Serialization Issues and bloated objects

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi Sagi,

Are you referring to the default profile provider that is using SqlExpress
as the database store? If this is the case, based on my test, the saved
personal information using profile provider will be all contained in one
table aspnet_Profile and there's only one record for one user.

Here's my test steps:

1) Create following classes:

namespace myns
{
[Serializable]
public class Member
{
private string _name;

public string Name
{
get { return _name; }
set { _name = value; }
}
private int _age;

public int Age
{
get { return _age; }
set { _age = value; }
}

private Policies _policies;

public Policies Policies
{
get { return _policies; }
set { _policies = value; }
}

}

[Serializable]
public class Policy
{
private int _id;

public int Id
{
get { return _id; }
set { _id = value; }
}
private string _name;

public string Name
{
get { return _name; }
set { _name = value; }
}

public Policy()
{
}

public Policy(int id, string name)
{
_id = id;
_name = name;
}
}

[Serializable]
public class Policies : List<Policy>
{
}
}


2) Edit web.config to support profile:

<profile>
<properties>
<add name="Name" type="string"/>
<add name="Member" type="myns.Member"/>
</properties>
</profile>

3) In Default.aspx.cs

if (string.IsNullOrEmpty(Profile.Name))
{
Profile.Name = "Test";
}

if (Profile.Member.Policies == null)
{
Profile.Member.Age = 1;
Profile.Member.Name = "Name";
Profile.Member.Policies = new Policies();
Profile.Member.Policies.Add(new Policy(1, "n1"));
Profile.Member.Policies.Add(new Policy(2, "n2"));
}

4) Open App_Data\AspNetDb.mdf, view table aspnet_Profile's data. It only
contains one record for the user. The field PropertyNames has following
content: "Name:S:0:4:Member:S:4:365:" while there're other two fields used
to store the serialized value:

Test<?xml version="1.0" encoding="utf-16"?>
<Member xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<Name>Name</Name>
<Age>1</Age>
<Policies>
<Policy>
<Id>1</Id>
<Name>n1</Name>
</Policy>
<Policy>
<Id>2</Id>
<Name>n2</Name>
</Policy>
</Policies>
</Member>


I think you may referring to other profile provider. Please let me know
your usage scenario. Thanks.
