我试图在用Visual Studio 2012编写的Windows Communication Foundation项目中使用以下类:
[DataContract]
public class SimCoilData : SimInventoryItemData
{
[DataMember]
public UnitTemperature? RequiredCoolingHotspot { get; set; }
[DataMember]
public UnitTemperature? RequiredHeatingColdspot { get; set; }
[DataMember]
public UnitTemperature? HeatingHotspotLimit { get; set; }
[DataMember]
public TimeSpan? TimeToRequiredColdspot { get; set; }
[DataMember]
public TimeSpan? TimeToRequiredCoolingHotspot { get; set; }
[DataMember]
public TimeSpan? TimeToHeatingHotspotLimit { get; set; }
[DataMember]
public UnitLength Gauge { get; set; }
[DataMember]
public UnitLength Width { get; set; }
[DataMember]
public double[] Temperatures { get; set; }
public SimCoilData() : base()
{
}
}
在添加Temperatures数组之前,服务器和客户端之间的数据交换良好。我添加了Temperatures数组,重建了服务器应用程序,并运行了它。然后,在客户端项目中,我更新了服务参考并重建了项目。运行客户端时,收到一条错误消息,提示您收到了毫无意义的回复,这可能是由某些原因引起的,包括数据合同不匹配。我已经验证了服务器端正在填充该阵列。调整客户端应用程序以接受数组的正确步骤是什么?
答案 0 :(得分:0)
问题似乎是我没有在客户端中为消息保留足够的空间。我发现我可以处理每个对象250次,但不能处理300次。 Google搜索“ WCF最大邮件大小”导致我找到maxBufferSize和maxReceivedMessageSize参数。通过为我的客户端进行此配置,我可以在数组中获取所有1800个值:
<?xml version="1.0" encoding="utf-8" ?>

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
