I am using asp.net and have configured the sessions to stored in SQL server. My porject has many object and several linq-to-sql dbml's. I have configured all the them to have unidirectional serialization and also made a few customized changes.
When I run the app I keep getting this error in my application_error event handler
Type 'Data.Karaoke.spCWP_SelUserPrivilegesResult' in Assembly 'App_Code.thzd8p2j, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.
from the error I am not sure if it is coming from the dbml.designer.cs file which this is the code:
[Function(Name="dbo.spCWP_SelUserPrivileges")]
public ISingleResult<spCWP_SelUserPrivilegesResult> spCWP_SelUserPrivileges([Parameter(Name="IDCWPUser", DbType="Int")] System.Nullable<int> iDCWPUser)
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), iDCWPUser);
return ((ISingleResult<spCWP_SelUserPrivilegesResult>)(result.ReturnValue));
}
and
[DataContract()]
public partial class spCWP_SelUserPrivilegesResult
{
private int _IDTypeCWPModule;
private string _TypeKey;
private bool _Security;
public spCWP_SelUserPrivilegesResult()
{
}
[Column(Storage="_IDTypeCWPModule", DbType="Int NOT NULL")]
[DataMember(Order=1)]
public int IDTypeCWPModule
{
get
{
return this._IDTypeCWPModule;
}
set
{
if ((this._IDTypeCWPModule != value))
{
this._IDTypeCWPModule = value;
}
}
}
[Column(Storage="_TypeKey", DbType="VarChar(10) NOT NULL", CanBeNull=false)]
[DataMember(Order=2)]
public string TypeKey
{
get
{
return this._TypeKey;
}
set
{
if ((this._TypeKey != value))
{
this._TypeKey = value;
}
}
}
[Column(Storage="_Security", DbType="Bit NOT NULL")]
[DataMember(Order=3)]
public bool Security
{
get
{
return this._Security;
}
set
{
if ((this._Security != value))
{
this._Security = value;
}
}
}
}
How can I determine where the error originated from? Or what does the error mean?
i am unsure how to solve or what to look for to solve the issue.
It seems like you are running some type of serialization in your application. A serialization different than DataContract Serialization.
Create a new file and enter the following:
[Serializable]
public partial class spCWP_SelUserPrivilegesResult { }
You do this in a separate file in case you refresh your dbml file from the database.
