Deserialization error when attribute is bool

I'm trying to deserialize a xml into a class but it's giving me an exception.

My class is something like that:

public class FieldsVO
    {    
        public bool AllowPrint { get; set; }
        public bool AllowAbort { get; set; }
        public bool AllowPrintFSFSDA { get; set; }
    }

And my XML:

<fields>
    <AllowPrint>True</AllowPrint>
    <AllowAbort>True</AllowAbort>
    <AllowPrintFSFSDA>True</AllowPrintFSFSDA>
</fields>

The only way that the deserialization works is if the attributes are "string". There is any way to do it with anotations or something?

Here's the deserialization code:

public static object Deserialize(string xml, Type objType)
        {
            if (false == xml.StartsWith("<"))
            {
                int pos = xml.IndexOf('<');
                xml = xml.Remove(0, pos);
            }
            XmlSerializer serializer = new XmlSerializer(objType);
            XmlReaderSettings set = new XmlReaderSettings();
            set.ValidationFlags = XmlSchemaValidationFlags.AllowXmlAttributes;
            using (XmlReader reader = XmlReader.Create(new StringReader(xml), set))
                return serializer.Deserialize(reader);
        }

When you want to parse XML, you should use XSD Schema.

XSD Schema describes a XML file.

For add this file: create an element -> XML Schema. Call this file fields.xsd.

In your case, it will be:

<xs:element name="fields">
<xs:complexType>
  <xs:sequence>
   <xs:element name="AllowPrint" type="xs:boolean"/>
   <xs:element name="AllowAbort" type="xs:boolean"/>
   <xs:element name="AllowPrintFSFSDA" type="xs:boolean"/>
  </xs:sequence>
</xs:complexType>
</xs:element>

Then, open the command-line interface. go to the directory where the fields.xsd is. enter:

xsd fields.xsd /classes

fields.cs is now generate.

In your XML file, you have to add: - the namespace of the XSD Schema - the location of the XSD Schema

      xmlns="urn:fields"
      xsi:schemaLocation="urn:fields fields.xsd">
