xmlwriter代替deserialize来进行性能优化

首先上代码，这边是抽象类里面的基类实现方法：

  public abstract class XmlConfigParser<TResult, TResource> : IConfigParser<TResult, TResource>         where TResource : Resource<TResult>        where TResult:class    {        public virtual TResult Parse(ref TResource resource)        {            Monitor.Watch("begin XmlConfigParse.");            TResult result = null;            XmlSerializer xs = new XmlSerializer(typeof (TResult));            result = xs.Deserialize(resource.Stream) as TResult;            resource.ParseLevel = Enum.ParseLevel.Detail;            resource.Stream.Close();            resource.Stream.Dispose();            resource.Stream = null;            Monitor.Watch("end XmlConfigParse.");            return result;        }        public virtual TResult ParseSchema(ref TResource resource)        {            return resource.Entity;        }

我这边用xmlwrite直接代替，虽然冗余但是速度的确快：

    public class XmlReadQueryConfigParser : XmlQueryConfigParser    {        public override Query Parse(ref QueryResource resource)        {            Query query = new Query();            Monitor.Watch("begin XmlReadQueryConfigParser.");            using (XmlReader xmlReader = XmlReader.Create(resource.Stream))            {                var propertyIndex = 0;                var dataQueryIndex = 0;                while (xmlReader.Read())                {                    switch (xmlReader.NodeType)                    {                        case XmlNodeType.Element:                            if ("Formatter".Equals(xmlReader.Name, StringComparison.CurrentCulture))                            {                                Formatter formatter = new Entity.Formatter()                                {                                    Id = xmlReader.GetAttribute("Id"),                                    Ref = xmlReader.GetAttribute("Ref"),                                    Class = xmlReader.GetAttribute("Class"),                                    CreateType =                                        xmlReader.GetAttribute("Type") == FormatterCreateType.ByClass.ToString()                                            ?
