获取错误,当我运行的代码以下错误消息的WCF数据服务:WCF数据服务业务经营
"The server encountered an error processing the request. See server logs for more details."
代码:
public class WcfDataService1 : DataService<Entities1>
{
// This method is called only once to initialize service-wide policies.
public static void InitializeService(DataServiceConfiguration config)
{
// TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc.
// Examples:
config.SetEntitySetAccessRule("*", EntitySetRights.All);
config.SetServiceOperationAccessRule("GetData", ServiceOperationRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
}
[WebGet()]
public IQueryable GetData(int Id)
{
if (assayId > 0)
{
var query = from a in this.CurrentDataSource.Entity
where a.ID == Id
select a;
return query;
}
else
throw new DataServiceException(400, "ID is not valid");
}
}
当我不返回任何相同的代码工作从操作。
UPDATE:服务器日志中说:
