I have this class model here:
public class Config
{
public ConnectionConfig ConnectionConfig { get; set; }
[XmlAttribute(AttributeName="advanced")]
public bool AdvancedEnabled { get; set; }
}
public class ConnectionConfig
{
[XmlElement(ElementName = "instance")]
public List<InstanceConfig> Instances { get; set; }
}
public class InstanceConfig
{
[XmlText]
public string Uri { get; set; }
[XmlAttribute(AttributeName="username")]
public string Username { get; set; }
[XmlAttribute(AttributeName="password")]
public string Password { get; set; }
}
Serialized it is this XML:
<config advanced="false">
<ConnectionConfig>
<instance username="user1" password="123">http://localhost:1234</instance>
<instance username="user2" password="1234">http://localhost:1235</instance>
<instance username="user3" password="12345">http://localhost:1236</instance>
</ConnectionConfig>
</config>
But I want to have a XML like this:
<config advanced="false">
<instance username="user1" password="123">http://localhost:1234</instance>
<instance username="user2" password="1234">http://localhost:1235</instance>
<instance username="user3" password="12345">http://localhost:1236</instance>
</config>
So basically without "ConnectionConfig". But in my model I need "ConnectionConfig" as an own object.
What am I missing or not understanding?
I tried to move the [XmlElement(ElementName = "instance")] attribute to ConnectionConfig but still not my desired output.
I haven't verified it, but I think you might need to decorate the ConnectionConfig property to indicate that it is an element in its own right.
public class Config
{
[XmlElement("ConnectionConfig")]
public ConnectionConfig ConnectionConfig { get; set; }
[XmlAttribute(AttributeName="advanced")]
public bool AdvancedEnabled { get; set; }
}

I have an XML file that looks something similar to this:
<root>
<data label="product data" min="0" max="10">
<option>
<id>1</id>
<name>Name1</name>
</option>
<option>
<id>2</id>
<name>Name2</name>
</option>
<option>
<id>3</id>
<name>Name3</name>
</option>
</data>
</root>
I need to retreive both data attributes and the option list.
I tried this:
[XmlRoot(ElementName = "root")]
public class Data
{
// Retreive data attributes
[XmlElement(ElementName = "data")]
public Options Attributes { get; set; }
// Retrieve option list
[XmlArray("data")]
[XmlArrayItem("option", Type = typeof(GeneralOptions))]
public GeneralOptions[] Options { get; set; }
}
Optional classes:
Options
public class Options
{
[XmlAttribute("label")]
public string Label{ get; set; }
[XmlAttribute("min")]
public string Min{ get; set; }
[XmlAttribute("max")]
public string Max{ get; set; }
}
GeneralOptions
public class GeneralOptions
{
[XmlElement(ElementName = "id")]
public string Id { get; set; }
[XmlElement(ElementName = "name")]
public string Name{ get; set; }
}
But when I try to deserialize the object, it launches the following exception:
The XML element 'data' from namespace '' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element.
I imagine the problem is that I'm trying to retreive the same element "twice". But I need to retreive both things. I cannot use the [Attribute] thing because there are several Attributes to retreive, and I need to do this with several XML Elements with the same format and I want to reuse it.
So, how can I retreive both of them?
You'll need to restructure it slightly:
[XmlRoot("root")]
public class Data
{
[XmlElement("data")]
public OptionsData Options { get; set; }
}
public class OptionsData
{
[XmlAttribute("label")]
public string Label { get; set; }
[XmlAttribute("min")]
public string Min { get; set; }
[XmlAttribute("max")]
public string Max { get; set; }
[XmlElement("option")]
public List<GeneralOptions> Items { get; } = new List<GeneralOptions>();
}
public class GeneralOptions
{
[XmlElement("id")]
public string Id { get; set; }
[XmlElement("name")]
public string Name { get; set; }
}
I suggest using xmltocsharp or anyother tools to convert the XML to C# Models within seconds... (eliminates all manual mistakes)
As mentioned by #canton7, another easy method is using Visual Studio: Edit -> Paste Special -> Paste XML As Classes
[XmlRoot(ElementName="option")]
public class Option {
[XmlElement(ElementName="id")]
public string Id { get; set; }
[XmlElement(ElementName="name")]
public string Name { get; set; }
}
[XmlRoot(ElementName="data")]
public class Data {
[XmlElement(ElementName="option")]
public List<Option> Option { get; set; }
[XmlAttribute(AttributeName="label")]
public string Label { get; set; }
[XmlAttribute(AttributeName="min")]
public string Min { get; set; }
[XmlAttribute(AttributeName="max")]
public string Max { get; set; }
}
[XmlRoot(ElementName="root")]
public class Root {
[XmlElement(ElementName="data")]
public Data Data { get; set; }
}
This is my first time to ask on stackoverflow and also the first time to work with xml files , so I don't think it can get worse than that.
I need to deserialize some long XML but the part thats bugging me is the following:
<CastleConfigSub xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../xsd/c5c.xsd" Format="1">
<ConfigFile Name="EdgeDetection">
<Interfaces>

<Functions>
<Function Name="MonitorNoChanges">
<Doc>This Function checks that no edge has been detected at the specified digital channel for a specific time in msec
1. DigitalChanelToWatch: This is the digital Input channel to monitor edges on it.
2. TimeOut: This is the monitoring Period for the edges on the digitial input channel.
</Doc>

public class CastleConfigSub
{
[XmlElement("Options")]
public Options options = new Options();
[XmlElement("ConfigFile")]
public ConfigFile configFile= new ConfigFile();
}
public class ConfigFile
{

public string doc {get; set;}
[XmlElement("History")]
public History history = new History();

}
public class Function

public string doc="";
[XmlArray("Args")]
[XmlArrayItem("Arg")]
public List<Arg> args = new List<Arg>();
}
public class Arg
{
[XmlAttribute ("xsi:type")]
public string type = "";
[XmlAttribute("Name")]
public string name ="";
[XmlAttribute("EncodedType")]
public string encodedType="";
[XmlAttribute("Enum")]
public string enumName ="";
[XmlAttribute("Unit")]
public string unit="";
}
I know everthing is so messy but i couldnt do any better :/.
Please try this:
public class CastleConfigSub
{
public ConfigFile ConfigFile { get; set; }
[XmlAttribute()]
public byte Format { get; set; }
}
public class ConfigFile
{
public List<Interface> Interfaces { get; set; }
[XmlAttribute()]
public string Name { get; set; }
}
public class Interface
{
public object Doc { get; set; }
public List<Function> Functions { get; set; }
[XmlAttribute()]
public string Name { get; set; }
}
public class Function
{
public string Doc { get; set; }
[XmlArrayItem("Arg")]
public List<Arg> Args { get; set; }
[XmlAttribute()]
public string Name { get; set; }
}
[XmlInclude(typeof(ArgEnum))]
[XmlInclude(typeof(ArgValue))]
public class Arg
{
[XmlAttribute()]
public string Name { get; set; }
}
public class ArgEnum : Arg
{
[XmlAttribute()]
public string Enum { get; set; }
}
public class ArgValue : Arg
{
[XmlAttribute()]
public string EncodedType { get; set; }
[XmlAttribute()]
public string Unit { get; set; }
}
I do not know how many times Interface and Function elements exists. So I made the List collection.
The previous answer is a good one, and helped me to solve my issue, but I've got extra work to handle different namespaces in xml element and it's attribute value, so my solution is here:
Having following xml
<?xml version="1.0" encoding="utf-16"?>
<RootType xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://my.custom.namespace.com">
<description>some description</description>
<values>
<field>some field</field>
<value xsi:type="xsd:double">1000.00</value>
</values>
</RootType>
The deserialized objects set is following
[XmlRoot(ElementName = "RootType", Namespace = "http://my.custom.namespace.com")]
public sealed class Root
{
[XmlElement("description")]
public string Description { get; set; }
[XmlElement("values")]
public Value[] Values { get; set; }
}
public sealed class Value
{
[XmlElement("field")]
public string Field { get; set; }
[XmlElement("value", IsNullable = true)]
public ValueProperty ValueProperty { get; set; }
}
[XmlInclude(typeof(CustomDouble))]
[XmlRoot(Namespace = "http://my.custom.namespace.com")]
public class ValueProperty
{
[XmlText]
public string Value { get; set; }
}
[XmlType(TypeName = "double", Namespace = "http://www.w3.org/2001/XMLSchema")]
public class CustomDouble : ValueProperty
{
}
I have the following XML which I need to deserialize:
<?xml version="1.0" encoding="UTF-8" ?>
<event code="2wuj0ticofhzt" self="/events/2wuj0ticofhzt" revision="1260234836">
<name>Test Event 2013</name>
<partner-settings>
<partner-setting>
<registration-type code="1yfopbwhk" link="/registration-types/1yfopbwhk" />
<personnel code="3eclag1dsrjfi">
<free-badges>unlimited</free-badges>
</personnel>
<personnel code="0nxgc6mfec8yh">
<free-badges>3</free-badges>
</personnel>
</partner-setting>
<partner-setting>
<registration-type code="1ygg67prw" link="/registration-types/1ygg67prw" />
</partner-setting>
</partner-settings>
</event>
Here are my classes that I have created. (I only need to deserialize the fields I have in my classes.):
[XmlRoot("event")]
public class Event
{
[XmlAttribute("code")]
public string Code { get; set; }
[XmlAttribute("name")]
public string EventName { get; set; }
[XmlArray("partner-settings")]
public List<PartnerSetting> PartnerSettings { get; set; }
}
[XmlType("partner-setting")]
public class PartnerSetting
{
[XmlElement("registration-type")]
public RegistrationType RegistrationType { get; set; }
[XmlArray("personnel")]
public List<Personnel> Personnel { get; set; }
}
[XmlRoot("registration-type")]
public class RegistrationType
{
[XmlAttribute("code")]
public string Code { get; set; }
[XmlAttribute("name")]
public string RegistrationTypeName { get; set; }
[XmlElement("type")]
public string Type { get; set; }
}
[XmlType("personnel")]
public class Personnel
{
[XmlAttribute("code")]
public string Code { get; set; }
[XmlElement("free-badges")]
public int FreeBadges { get; set; }
}
When I currently deserialize the above XML it all works except from the Personnel object where I get 0 returned when I'm expecting to see 2.
I'm not doing anything differently when I'm trying to return a personnel list (i.e. XMLArray attribute, return a List) to a partner setting list but for some reason it won't deserialize.
You need to change the attribute into XmlElement to force each element in the list to be rendered as a single XML element:
[XmlElement("personnel")]
public List<Personnel> Personnel { get; set; }
First, i tried on the internet different ways, but i didn't got what i want. i have viewmodel class with the following properties;
public class UserEntitySubmissionsReportViewModel
{
public UserEntitySubmissionsReportViewModel()
{
Submissions = new FinalUserEntitiesAssignmentViewModel();
}
public int Id { get; set; }
public int Status { get; set; }
public DateTime SubmissionDate { get; set; }
public int UserEntityAssignmentId { get; set; }
public FinalUserEntitiesAssignmentViewModel Submissions { get; set; }
}
and the nested class FinalUserEntitiesAssignmentViewModel whcih is;
[Serializable]
public class FinalUserEntitiesAssignmentViewModel
{
public FinalUserEntitiesAssignmentViewModel()
{
ProjectInformation = new ProjectInformationViewModel();
MilestoneInformation = new MilestoneInformationViewModel();
ActivityListInformation = new ActivityListInformationViewModel();
ActivityInformation = new ActivityInformationViewModel();
SubActivityInformation = new List<SubActivityInformationViewModel>();
}
[XmlElement(ElementName = "ProjectInformation")]
public ProjectInformationViewModel ProjectInformation { get; set; }
[XmlElement(ElementName = "MilestoneInformation")]
public MilestoneInformationViewModel MilestoneInformation { get; set; }
[XmlElement(ElementName = "ActivityListInformation")]
public ActivityListInformationViewModel ActivityListInformation { get; set; }
[XmlElement(ElementName = "ActivityInformation")]
public ActivityInformationViewModel ActivityInformation { get; set; }
[XmlElement(ElementName = "SubActivityInformation")]
public List<SubActivityInformationViewModel> SubActivityInformation { get; set; }
}
[Serializable]
public class ProjectInformationViewModel
{
[XmlElement(ElementName = "Id")]
public int Id { get; set; }
[XmlElement(ElementName = "Name")]
public string Name { get; set; }
public string Description { get; set; }
}
When i serialize this, i only get the 1 property i.e Id for nested class.
var obj = new UserEntitySubmissionsReportViewModel();
var writer = new System.Xml.Serialization.XmlSerializer(typeof(UserEntitySubmissionsReportViewModel));
System.IO.StreamWriter file = new System.IO.StreamWriter(Server.MapPath("~/App_Data/UserEntitySubmissionsReportViewModel.xml"));
writer.Serialize(file, obj);
file.Close();
The result i get is;
<?xml version="1.0" encoding="utf-8"?>
<UserEntitySubmissionsReportViewModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Id>0</Id>
<Status>0</Status>
<SubmissionDate>0001-01-01T00:00:00</SubmissionDate>
<UserEntityAssignmentId>0</UserEntityAssignmentId>
<Submissions>
<ProjectInformation>
<Id>0</Id>
</ProjectInformation>
<MilestoneInformation>
<Id>0</Id>
</MilestoneInformation>
<ActivityListInformation>
<Id>0</Id>
</ActivityListInformation>
<ActivityInformation>
<Id>0</Id>
<Attributes />
<Tools />
</ActivityInformation>
</Submissions>
</UserEntitySubmissionsReportViewModel>
As you can see, i am not able to serialize other properties. Similarly i have nest collection too. How can i serialize nested properties using C# ?
I think that when serializing XML that you need to define a default constructor for your classes. Try adding a construction for your ProjectInformationViewModel class.
public class ProjectInformationViewModel
{
// Default Constructor
public ProjectInformationViewModel()
{
}
}
Given the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<userAttributeList>
<attribute>
<userId>12345678</userId>
<attId>1234</attId>
<attName>Group</attName>
<attTypeId>8</attTypeId>
<attTypeName>User Group</attTypeName>
<attData>Member</attData>
</attribute>
<attribute>
<userId>12345678</userId>
<attId>1235</attId>
<attName>Contact Name</attName>
<attTypeId>16</attTypeId>
<attTypeName>Contact Center Greeting</attTypeName>
<attData>John Smith</attData>
</attribute>
...
</userAttributeList>
I want to deserialize it into the following classes:
[Serializable]
[XmlTypeAttribute(AnonymousType = true)]
public class UserAttributeList
{
[XmlArray(ElementName = "userAttributeList")]
[XmlArrayItem(ElementName = "attribute")]
public List<UserAttribute> attributes { get; set; }
public UserAttributeList()
{
attributes = new List<UserAttribute>();
}
}
[Serializable]
public class UserAttribute
{
public String userId { get; set; }
public String attId { get; set; }
public String attName { get; set; }
public String attTypeId { get; set; }
public String attTypeName { get; set; }
public String attData { get; set; }
}
Using the code below, where GetResponseStream() returns the XML object listed above:
XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "userAttributeList";
xRoot.IsNullable = true;
XmlSerializer serializer = new XmlSerializer(typeof(UserAttributeList), xRoot);
try
{
return (UserAttributeList)serializer.Deserialize(request.GetResponse().GetResponseStream());
}
catch (Exception exc)
{
return null;
}
My code compiles with no errors, but the UserAttributeList that is returned shows no child "attribute" items. No errors are thrown
I would sooner do something like:
public class userAttributeList
{
[XmlElement]
public List<UserAttribute> attribute { get; set; }
public UserAttributeList()
{
attribute = new List<UserAttribute>();
}
}
public class UserAttribute
{
public int userId { get; set; }
public int attId { get; set; }
public string attName { get; set; }
public int attTypeId { get; set; }
public string attTypeName { get; set; }
public string attData { get; set; }
}
Personally I'd use LinqToXsd. Take the existing xml, generate an xsd from it then use LinqToXsd to load that xml into a LinqToXsd object. Then you can do things like:
xml.company.com.reports.report.Load(xmlFileContents);
to build a POCO.
