ServiceStack的新手，并尝试了解JSon客户端和SqlServer数据库的一些示例。我有像这样的DTO对象：
public class InspectionResults : IHasIntId
{
[AutoIncrement]
[PrimaryKey]
[Alias("OID")]
public int Id { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public string Instructions { get; set; }
public string Frequency { get; set; }
public Boolean Active { get; set; }
public DateTime ChangedDate { get; set; }
public DateTime CreatedDate { get; set; }
public int LocationID { get; set; }
public DateTime AssignedDate { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public int InspectorID { get; set; }
public string Notes { get; set; }
}
当我填充属性并尝试发布我收到Sqlerrors with Overflow on Date。这是我的Populate和Post。属性中的所有数据都显示正常。
var client = new JsonServiceClient("http://localhost:50238/InspectionResults?");
var res = client.Post( new InspectionResults
{
Active = inspection.Active,
AssignedDate = DateTime.Now.AddHours(-3),
ChangedDate = DateTime.Now,
CreatedDate = DateTime.Now,
Description = inspection.Description,
EndDate = DateTime.Now,
Frequency = inspection.Frequency,
InspectorID = 2,
Instructions = inspection.Instructions,
LocationID = inspection.LocationID,
Notes = "These are my dummy notes for the whole Inspection",
StartDate = DateTime.Now.AddMinutes(-55),
Title = inspection.Title
});
以下是响应主体

感谢您的任何指导。
添加了DataWorkerClass：
public class InspectionResultsDataWorker
{
/// <summary>
/// A helper class that uses the ServiceStack.OrmLite Object Relational Mapper
/// to support CRUD operations on the InspectionResults table.
/// </summary>
// The IDbConnection passed in from the IOC container on the service
System.Data.IDbConnection _dbConnection;
// Store the database connection passed in
public InspectionResultsDataWorker(System.Data.IDbConnection dbConnection)
{
_dbConnection = dbConnection;
}
// Inserts a new row into the InspectionResults table
public int AddInspectionResults(InspectionResults i)
{
return (int)_dbConnection.Insert<InspectionResults>(i, selectIdentity: true);
}
// Return a list of InspectionResultss from our DB
// (this is the equivilent of “SELECT * FROM InspectionResults”)
public List<InspectionResults> GetInspectionResultsList()
{
var inspectionResults = _dbConnection.Select<InspectionResults>();
var inspectionResultsItems = _dbConnection.Select<InspectionResultsItem>();
List<InspectionResults> returnList = new List<InspectionResults>();
foreach (InspectionResults ins in inspectionResults)
{
List<InspectionResultsItem> inspItemList = _dbConnection.Select<InspectionResultsItem>(q => q.InspectionResultsID == ins.Id);
// ins.InspectionResultsItems = inspItemList;
returnList.Add(ins);
}
return returnList;
}
// Return a single InspectionResults given its ID
public InspectionResults GetInspectionResultsByID(int id)
{
return _dbConnection.SingleById<InspectionResults>(id);
}
// Updates a row in the InspectionResults table. Note that this call updates
// all fields, in order to update only certain fields using OrmLite,
// use an anonymous type like the below line, which would only
// update the Title and Description fields:
// _dbConnection.Update(new { Title = “Inspect Tractors”, Description = “Check all Aspects of Tractor Operation” });
public InspectionResults UpdateInspectionResults(InspectionResults i)
{
_dbConnection.Update<InspectionResults>(i);
return i;
}
// Deletes a row from the InspectionResults table
public int DeleteInspectionResultsByID(int id)
{
return _dbConnection.Delete(id);
}
}
添加了Service Post和Add方法： //创建一个新的InspectionResults public int Post（InspectionResultsRequest request） { var p = new InspectionResults（） {
};
InspectionResultsDataWorker pdp = new InspectionResultsDataWorker(Db);
return pdp.AddInspectionResults(p);
}
// Inserts a new row into the InspectionResults table
public int AddInspectionResults(InspectionResults i)
{
return (int)_dbConnection.Insert<InspectionResults>(i, selectIdentity: true);
}
