unable to deserialize from serialized XML

I am unable to deserialize from serialized XML. Below is the code. I do know that if I completely remove the xmlns attributes the XML is then well forms and can be deserialized.

Class XML derives from:

using System;
using System.Collections.Generic;
using System.Runtime.Serialization;
using System.Xml.Serialization;

namespace MyNamespace
{
    [DataContract(Name = "MyClass", Namespace = "")]
    public class MyClass
    {
        public MyClass()
        {
        }

        public MyClass(string _Total2, string _Total1)
        {
            Total2 = _Total2;
            Total1 = _Total1;
        }

        [DataMember(Name = "Total2", EmitDefaultValue = false)]
        public string Total2 { get; set; }

        [DataMember(Name = "Total1", EmitDefaultValue = false)]
        public string Total1 { get; set; }
    }
}


XML output:

<GetResponse xmlns=\"http://tempuri.org/\"><GetResult xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\"><Total1 xmlns=\"\">100</Total1><Total2 xmlns=\"\">200</Total2 ></GetResult></GetResponse>



Deserialization method:

public static T DeserializeFromXml<T>(string xml)
{
    T result;
    var ser = new XmlSerializer(typeof(T));
    using (TextReader tr = new StringReader(xml))
    {
        result = (T)ser.Deserialize(tr);
    }
    return result;
}
