Asp.net web服务返回空对象

我有一个XSD文件，它决定了我的引擎可以与其他插件(用不同的语言编写，如Delphi)通信的模式。我使用。net提供的XSD工具从XSD文件中获得一个c#类。

插件返回一个XML字符串，然后我将其反序列化为XSD工具生成的类。

在此之前一切都很好，但是当我通过web服务将类的数组传递给客户端时，该数组包含一个元素，这很好，但该对象中的每个字段要么为空，要么设置为默认值。

你知道为什么会这样吗?

我也尝试发送虚拟数据，而不是从插件正常检索数据，但仍然返回的对象是空的。

这是由XSD工具生成的类:

using System.Xml.Serialization;

/// <remarks/>
[System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)]
public class BookingQueryResponse {
    /// <remarks/>
    public int ErrorCode;
    /// <remarks/>

    public HotelQuotePackage[] HotelQuotePackages;

    [System.Xml.Serialization.XmlElementAttribute("HotelRoomQuotes")]
    public HotelRoomQuote[] HotelRoomQuotes;
    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("HotelImages")]
    public HotelMediaImage[] HotelImages;
}
/// <remarks/>
public class HotelRoomQuote {
    /// <remarks/>
    public int RoomNumber;
    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("RoomQuotes")]
    public RoomQuote[] RoomQuotes;
}
/// <remarks/>
public class RoomQuote {
    /// <remarks/>
    public string Guid;
    /// <remarks/>
    public int AdultPax;
    /// <remarks/>
    public int ChildPax;
    /// <remarks/>
    public int InfantPax;
    /// <remarks/>
    public string RoomTypeName;
    /// <remarks/>
    public string RoomTypeDesc;
    /// <remarks/>
    public int BoardBasisID;
    /// <remarks/>
    public string BoardBasisName;
    /// <remarks/>
    public System.Double CostForStay;
    /// <remarks/>
    public string Remarks;
    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("DayRates")]
    public DayRate[] DayRates;
}
/// <remarks/>
public class DayRate {
    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute(DataType="date")]
    public System.DateTime Date;
    /// <remarks/>
    public System.Double Rate;
}
/// <remarks/>
public class HotelMediaImage {
    /// <remarks/>
    public string HotelImage;
    /// <remarks/>
    public int ImageTypeID;
    /// <remarks/>
    public string ImageType;
}

，只是为了测试的目的，我所做的是:

return return new BookingQueryResponse[1] { new BookingQueryResponse() { ArrivalDate = DateTime.Now.Date, DestinationName = "Malta" } };
