Decimal field not being deserialized while integer value works fine

Sample Xml:

<TestXML>
   <TestDecimal attr1="Required" attr2="false">0.34</TestDecimal>
   <TestInteger attr1="MyAttr" attr2="1" DateAdded="">25</TestInteger>
</TestXML>

Class Definitions:

public class TestXML {
   public DecimalValue TestDecimal;
   public IntegerValue TestInteger;
}

public class IntegerValue {
   [XmlText]
   public int value {get; set;}
   [XmlAnyAttribute]
   public XmlAttribute[] XAttributes {get; set;}
}
public class DecimalValue {
   [XmlText]
   public decimal value {get; set;}
   [XmlAnyAttribute]
   public XmlAttribute[] XAttributes {get; set;}
}

Code to deserialize:

XmlSerializer serializer = new XmlSerializer(typeof(TestXML));
using (FileStream fs = new FileStream(@"C:\Test.xml", FileMode.Open)) {
   TestXML myxml = (TestXML)serializer.Deserialize(fs);
}

In testing this it comes back with the integer value but not the decimal value:

myxml
   TestDecimal
      value |  0
      XAttributes  {string[2]}
         [0] Name="attr1", Value="Required"
         [1] Name="attr2", Value="false"
   TestInteger
      value |  25
      XAttributes  {string[3]}
         [0] Name="attr1", Value="MyAttr"
         [1] Name="attr2", Value="1"
         [2] Name="DateAdded", Value=""

Is there something about deserializing decimals that would cause it come back as 0? With the primitive type of decimal the decimal value comes back fine.

You must be doing something differently in your actual code than what you are showing here. Your code does not compile as posted - specifically class definitions don't have () after their names in C#.

This works for me as expected (the decimal value gets deserialized correctly):

using System;
using System.Diagnostics;
using System.Net;
using System.Net.Sockets;
using System.Xml;
using System.Xml.Serialization;
using System.IO;

namespace Test
{

    public class TestXML
    {
        public DecimalValue TestDecimal;
        public IntegerValue TestInteger;
    }

    public class IntegerValue
    {
        [XmlText]
        public int value {get; set;}
        [XmlAnyAttribute]
        public XmlAttribute[] XAttributes {get; set;}
    }

    public class DecimalValue
    {
        [XmlText]
        public decimal value {get; set;}
        [XmlAnyAttribute]
        public XmlAttribute[] XAttributes {get; set;}
    }

    class Program
    {

        static void Test()
        {
            XmlSerializer serializer = new XmlSerializer(typeof(TestXML));
            using (FileStream fs = new FileStream("Test.xml", FileMode.Open)) 
            {
                TestXML myxml = (TestXML)serializer.Deserialize(fs);
            }

        }

        static void Main(string[] args)
        {
            Test();
        }
    }
}

This is with a local test.xml file copied to the bin directory containing this data:

<TestXML>
    <TestDecimal attr1="Required" attr2="false">0.34</TestDecimal>
    <TestInteger attr1="MyAttr" attr2="1" DateAdded="">25</TestInteger>
</TestXML>
