我有从 ASP.Net oData 服务返回的 JSON 对象，我正在通过 JayData oData 提供程序读取这些对象。在一项服务中，JSON 对象被读取到一个数组中，没有任何问题。在另一个服务（来自同一服务器）上，结果数组仅包含所有元素的 etag 数据。

我不确定是否存在格式不匹配或 JayData 未正确解码 JSON 格式。

有人可以看看问题出在哪里吗？

这是 JSON 数据。

{"d":[{"__metadata":{"id":"http://localhost:56786/GCSData.svc/Customers(1)","uri":"http://localhost:56786/GCSData.svc/Customers(1)","etag":"W/\"'John%20%20%20%20%20%20','Doe%20%20%20%20%20%20%20','1234567890'\"","type":"LightSwitchApplication.Customer"},"Orders":{"__deferred":{"uri":"http://localhost:56786/GCSData.svc/Customers(1)/Orders"}},"CustID":1,"FName":"John      ","LName":"Doe       ","Phone":"1234567890"},{"__metadata":{"id":"http://localhost:56786/GCSData.svc/Customers(2)","uri":"http://localhost:56786/GCSData.svc/Customers(2)","etag":"W/\"'Jane%20%20%20%20%20%20','Smith%20%20%20%20%20','7703211234'\"","type":"LightSwitchApplication.Customer"},"Orders":{"__deferred":{"uri":"http://localhost:56786/GCSData.svc/Customers(2)/Orders"}},"CustID":2,"FName":"Jane      ","LName":"Smith     ","Phone":"7703211234"},{"__metadata":{"id":"http://localhost:56786/GCSData.svc/Customers(3)","uri":"http://localhost:56786/GCSData.svc/Customers(3)","etag":"W/\"'Dan%20%20%20%20%20%20%20','Handy%20%20%20%20%20','6789876543'\"","type":"LightSwitchApplication.Customer"},"Orders":{"__deferred":{"uri":"http://localhost:56786/GCSData.svc/Customers(3)/Orders"}},"CustID":3,"FName":"Dan       ","LName":"Handy     ","Phone":"6789876543"},{"__metadata":{"id":"http://localhost:56786/GCSData.svc/Customers(4)","uri":"http://localhost:56786/GCSData.svc/Customers(4)","etag":"W/\"'Mike%20%20%20%20%20%20','Smith%20%20%20%20%20','4041231234'\"","type":"LightSwitchApplication.Customer"},"Orders":{"__deferred":{"uri":"http://localhost:56786/GCSData.svc/Customers(4)/Orders"}},"CustID":4,"FName":"Mike      ","LName":"Smith     ","Phone":"4041231234"},{"__metadata":{"id":"http://localhost:56786/GCSData.svc/Customers(5)","uri":"http://localhost:56786/GCSData.svc/Customers(5)","etag":"W/\"'Aaron%20%20%20%20%20','Hayes%20%20%20%20%20','2431235678'\"","type":"LightSwitchApplication.Customer"},"Orders":{"__deferred":{"uri":"http://localhost:56786/GCSData.svc/Customers(5)/Orders"}},"CustID":5,"FName":"Aaron     ","LName":"Hayes     ","Phone":"2431235678"}]}

在结果数组中，对于每个客户，所有字段（FName、LName、电话）都包含确切的数据（等于“etag”字段）。这是 Customer(1) 的示例

{"CustID":1,"FName":"W/\"'John%20%20%20%20%20%20','Doe%20%20%20%20%20%20%20','1234567890'\"","LName":"W/\"'John%20%20%20%20%20%20','Doe%20%20%20%20%20%20%20','1234567890'\"","Phone":"W/\"'John%20%20%20%20%20%20','Doe%20%20%20%20%20%20%20','1234567890'\""}

JSON 数据通过 toLiveArray() 方法读取。

确保您使用[TimeStamp]服务器端的属性以字节数组格式发布您的 ETag：

[Timestamp]
public byte[] token { get; set; }
