将Modelstate序列化为XML asp.net MVC

Question

Im trying the serialize the modelstate to an xml string. First I create a modelstate dictionary and this dictionary I try to serialize. This is the code I use:

 ModelStateDictionary dict = new ModelStateDictionary();
            dict.Merge(ModelState);
            XmlSerializer serializer = new XmlSerializer(dict.GetType());

            using (StringWriter writer = new StringWriter()){
                serializer.Serialize(writer, dict);

                var r2 = writer.ToString();

            }

r2 is created, but all tags are filled with \\r\\n. What am I doing wrong?

You could use a XmlWriter and specify in the settings that you don't want to keep whitespaces and indentation:

XmlSerializer serializer = new XmlSerializer(dict.GetType());
var settings = new XmlWriterSettings { Indent = false };
using (var stream = new MemoryStream())
using (var writer = XmlWriter.Create(stream, settings))
{
    serializer.Serialize(writer, dict);
    string r2 = Encoding.UTF8.GetString(stream.ToArray());
}
