c# - CodeGo.net> WCF错误 'There was an error while trying to serialize parameter...'

我的服务适用于其他方法，但是当我尝试调用具有更复杂集合的方法时，出现错误(来自Service Trace Viewer)

'尝试序列化参数http://tempuri.org/:GetDataEventSetResult时发生错误。 InnerException消息是“类型'MimosaServerLib.DAInt'，数据协定名称为'DAInt:http://schemas.datacontract.org/2004/07/MimosaServerLib'不会出现...”

与我所见相同错误的问题的答案涉及更改类定义以关闭“ProxyCreationEnabled”，但是我正在使用的类(DataEventSet，DAInt)来自使用我使用xsd工具自动生成的文件已经给出了。即，我不应该更改它。

我创建了DataEventSet对象，该对象是公开的，如下所示:

    private DataEventSet CreateDataEventSet()
    {
        DataEventSet aDataEventSet = new DataEventSet();
        DataEvent[] dataEvents = new DataEvent[2];
        DAInt aDAInt = new DAInt();
            aDAInt.id = 100100100;
            aDAInt.value = 1;
            dataEvents[0] = aDAInt;
        DADataSeq aDADataSeq = new DADataSeq();
            aDADataSeq.id = 200100100;
            double[] vals = new double[2];
                vals[0] = 5;
                vals[1] = 44;
            aDADataSeq.values = vals;
            double[] vals2 = new double[2];
                vals2[0] = 1;
                vals2[1] = 1;
            aDADataSeq.xAxisDeltas = vals2;
            aDADataSeq.xAxisStart = 0;
            dataEvents[1] = aDADataSeq;
        aDataEventSet.id = 0;
        Site aSite = new Site();
            aSite.category = SITE_CATEGORY.SITE_SPECIFIC;
        aDataEventSet.site = aSite;
        OsacbmTime aTime = new OsacbmTime();
            aTime.tick_time = 12313246;
            aTime.time = "2007-09-20T14:46:04.123";
            aTime.time_type = OsacbmTimeType.OSACBM_TIME_MIMOSA;
        aDataEventSet.time = aTime;
        aDataEventSet.dataEvents = dataEvents;

        return aDataEventSet;
    }

编辑:DataEventSet的类定义

最佳答案

我认为您需要将KnownType(typeof(DAInt))属性添加到DataEventSet类，因为您正在以多态方式使用它。我通常将更改添加到名为DataEventSet.xsd.nongenic.cs之类的新文件中的生成代码中。这就是为什么生成的代码将这些类创建为部分类的原因。

在DataEventSet.xsd.nongenic.cs内部，您将看到以下内容:

[KnownType(typeof(DAInt))]
public partial class DataEventSet {
}

如果这不起作用，那么您始终可以尝试更改契约(Contract)以使用XmlSerializer而不是DataContractSerializer。那应该很好用，因为它使用了xsd.exe创建的Xml属性。

您可以通过将XmlSerializerFormatter属性添加到服务协定来指定运行时使用XmlSerializer。
