我的服务适用于其他方法，但是当我尝试使用更复杂的集合调用方法时出现错误（来自 Service Trace Viewer）

'尝试序列化参数http://tempuri.org/:GetDataEventSetResult时出错。InnerException 消息是 'Type 'MimosaServerLib.DAInt' 与数据合同名称 'DAInt: http://schemas.datacontract.org/2004/07/MimosaServerLib ' 不是预期的......'

对我看到的具有相同错误的问题的答案涉及更改类定义以关闭“ProxyCreationEnabled”，但我正在使用的类（DataEventSet，DAInt）来自使用我一直使用的 xsd 工具自动生成的文件给定的。即我不应该改变它。

我创建了DataEventSet暴露的对象，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：的类定义DataEventSet

我认为您需要将KnownType(typeof(DAInt))属性添加到DataEventSet类中，因为您以多态方式使用它。我通常将我对生成代码的更改添加到一个名为 DataEventSet.xsd.nongenerated.cs 的新文件中。这就是生成的代码将类创建为部分类的原因。

在 DataEventSet.xsd.nongenerated.cs 中，您将拥有如下内容：

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

如果这不起作用，那么您可以随时尝试更改合同以使用.XmlSerializer而不是DataContractSerializer. 这应该很好用，因为它使用由 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 。
