如何将字符串中包含的XML解析为IList <BusinessObject>？

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

[Serializable]
public class BusinessObject
{
    public string Property1 { get; set; }
    public int Property2 { get; set; }
}

public class XmlParser
{
    public static IList<BusinessObject> DeserializeXml(string xmlString)
    {
        IList<BusinessObject> result;
        using (StringReader stringReader = new StringReader(xmlString))
        {
            XmlSerializer serializer = new XmlSerializer(typeof(List<BusinessObject>));
            result = (List<BusinessObject>)serializer.Deserialize(stringReader);
        }
        return result;
    }
}

string xmlString =<ArrayOfBusinessObject><BusinessObject<Property1>Value1</Property1<Property2>123</Property2></BusinessObject><BusinessObject<Property1>Value2</Property1<Property2>456</Property2></BusinessObject></ArrayOfBusinessObject>";
IList<BusinessObject> businessObjects = XmlParser.DeserializeXml(xmlString);
