How to use DataContractSerializer to create xml with tag names that match my known types
- by mezoid
I have the following data contract:
[CollectionDataContract(Name="MyStuff")]
public class MyStuff : Collection<object> {}
[DataContract(Name = "Type1")]
[KnownType(typeof(Type1))]
public class Type1
{
[DataMember(Name = "memberId")] public int Id { get; set; }
}
[DataContract(Name = "Type2")]
[KnownType(typeof(Type2))]
public class Type2
{
[DataMember(Name = "memberId")] public int Id { get; set; }
}
Which I serialize to xml as follows:
MyStuff pm = new MyStuff();
Type1 t1 = new Type1 { Id = 111 };
Type2 t2 = new Type2 { Id = 222 };
pm.Add(t1);
pm.Add(t2);
string xml;
StringBuilder serialXML = new StringBuilder();
DataContractSerializer dcSerializer = new DataContractSerializer(typeof(MyStuff));
using (XmlWriter xWriter = XmlWriter.Create(serialXML))
{
dcSerializer.WriteObject(xWriter, pm);
xWriter.Flush();
xml = serialXML.ToString();
}
The resultant xml string looks like this:
<?xml version="1.0" encoding="utf-16"?>
<MyStuff xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://schemas.datacontract.org/2004/07/">
<anyType i:type="Type1">
<memberId>111</memberId>
</anyType>
<anyType i:type="Type2">
<memberId>222</memberId>
</anyType>
</MyStuff>
Does anyone know how I can get it to instead use the name of my known types rather than anyType in the xml tag?
I'm wanting it to look like this:
<?xml version="1.0" encoding="utf-16"?>
<MyStuff xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://schemas.datacontract.org/2004/07/">
<Type1>
<memberId>111</memberId>
</Type1>
<Type2>
<memberId>222</memberId>
</Type2>
</MyStuff>
