DateTime Serialization to XML

I have an C# serializable object with a DateTime property like this:

        public class MyClass {
            public DateTime Date1 {get;set;}
        }

When serialized to XML, it gives me something like this

        <MyClass>
              <Date1>2010-11-30T00:00:00</Date1>
        </MyClass>

I could not get it to give me this, which is in the proper  xml date format:

        <MyClass>
              <Date1>2010-11-30</Date1>
        </MyClass>

After a couple of wasted days, it turned out that the solution is really simple:

        public class MyClass {
            [System.Xml.Serialization.XmlElement("Date1", DataType="date")]
            public DateTime Date1 {get;set;}
        }
