web-services - XmlInclude 或 SoapInclude

Question

我正在开发一个网络服务，它返回我在网络服务中定义的类数组。当我测试它时，我得到:“System.InvalidOperationException:类型 WebSite+HostHeader 不是预期的。使用 XmlInclude 或 SoapInclude 属性指定静态未知的类型。”

部分代码如下:

[WebService(Namespace = "http://WebSiteInfo.Podiumcrm.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class WebSite : System.Web.Services.WebService
{
    public class WebSiteEntry
    {
        public string SiteName = "";
        public string Comment = "";
        public string IISPath = "";
        public int SiteID = 0;
        public ArrayList HostHeaders;

        public WebSiteEntry()
        {
        }
    }
    public class HostHeader
    {
        public string IPAddress = "";
        public int Port = 0;
        public string URL = "";

        public HostHeader()
        {
        }
    }


    [WebMethod(EnableSession = true)]
    [TraceExtension(Filename = @"C:\DotNetLogs\WebSiteServices.log")]
    public WebSiteEntry[] WebSites()
    {...}
}

当我尝试时:

[WebService(Namespace = "http://WebSiteInfo.Podiumcrm.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[XmlInclude(typeof(WebSiteEntry))]
[XmlInclude(typeof(WebSiteProperty))]
[XmlInclude(typeof(HostHeader))]

public class WebSite : System.Web.Services.WebService
{...}

我得到:“找不到类型或命名空间名称 XmlInclude(是否缺少 using 指令或程序集引用？)”

指点谁能给我编译和执行的咒语!

谢谢...

根据您收到的错误:

找不到类型或命名空间名称“XmlInclude”(是否缺少 using 指令或程序集引用？)

您似乎缺少 System.Xml.Serialization Namespace .您可以完全限定 XmlInclude 类型，如下所示:

System.Xml.Serialization.XmlInclude(typeof(WebSiteProperty))

或通过 using 指令添加命名空间:

using System.Xml.Serialization
