WCF and System.Runtime.Serialization error

Question

User811304085 posted

I changed from web refrence to service refrence in .Net 3.5, as a result it updated refrence.cs  

I am calling a wcf service and getting the following error. Before this this was working fine

<system.serviceModel>

Project1.Framework.RequestController.RequestConfigurationInfo' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute.  See the Microsoft .NET Framework documentation for other supported types.

Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute.  See the Microsoft .NET Framework documentation for other supported types.

Add a [DataContract] attribute to your RequestConfigurationInfo and a [DataMember] attribute to the properties you wish to serialize. You can read more here: http://msdn.microsoft.com/en-us/library/ms733127.aspx.

I am direclty accessing the property in reference.cs, where should I make [DataContract] , [DataMember] to resolve the issue

client.cs 

User GetUser(XmlNode node)
{
User user = new User();
foreach (XmlNode userNode in node)
{
switch (userNode.Name)
{
case "AdminType":
user.AdminType = ConvertToInt(userNode.InnerText,0);
break;
case "Email":
user.Email = ConvertToString(userNode.InnerText);
break;
case "FirstName":
user.FirstName = ConvertToString(userNode.InnerText);
break;
case "LastName":
user.LastName = ConvertToString(userNode.InnerText);
break;

case "LanguageCode":
user.LanguageCode = ConvertToString(userNode.InnerText);
break;
case "UserGuid":
if (ConvertToString(userNode.InnerText) != string.Empty)
{
user.UserGuid = new Guid(ConvertToString(userNode.InnerText));
}
break;
case "abc":
abc abc = new abc();
foreach (XmlNode abcNode in userNode)
{
switch (abcNode.Name)
{
case "SetupQuestionsDisplayed":
abc.SetupQuestionsDisplayed = ConvertToString(abcNode.InnerText);
break;
case "ClientTypeID":
abc.ClientTypeID = ConvertToInt(abcNode.InnerText,0);
break;
}

}
user.abc = abc;
break;
case "RMSUserCode":
user.RMSUserCode = ConvertToInt(userNode.InnerText,0);
break;
case "DataClients":


DataClient dataClient = new DataClient();
foreach (XmlNode dataClientNode in userNode)
{
//Some work
}
DataClient[] dataClients = {dataClient};
user.DataClients = dataClients;
break;
}
}
return user;
}

Hi,

When applied to the member of a type, specifies that the member is part of a data contract and is serializable by the DataContractSerializer. Here is an example shows a type to which the DataContractAttribute and DataMemberAttribute attributes have been applied:

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datamemberattribute.aspx
