I am building an app using the DotNetNuke 7 platform and am trying to write Geography data to the database. Here is some background on the project. I am building in VS 2012 and just upgraded to Server 2012 from 2008 R2. DotNetNuke 7 implements PetaPoco for the data layer and WebAPI.

我正在使用DotNetNuke 7平台构建应用程序，并尝试将地理数据写入数据库。以下是该项目的一些背景知识。我在VS 2012中构建，刚刚从2008 R2升级到Server 2012。 DotNetNuke 7为数据层和WebAPI实现了PetaPoco。

I hope what I provided is enough to information to understand the problem. My code fails on the line "rep.Insert(location);"

我希望我提供的信息足以让我们了解问题。我的代码在“rep.Insert（location）;”行上失败了

using System.Linq;

using System.Net.Http;
using System.Web.Http;
using System.Data.Spatial;
using DotNetNuke.Web.Api;
using DotNetNuke.Data;


namespace DotNetNuke.Modules.GeoLocations
{
    public class LocationController: DnnApiController
    {
        [AllowAnonymous]
        [HttpPost]
        [ValidateAntiForgeryToken]
        public HttpResponseMessage addLocation(CP_Location submitted)
        {

            submitted.GeoCode = DbGeography.PointFromText(string.Format("POINT({0} {1})", submitted.Long, submitted.Lat), 4326);
            createLocation(submitted);

            return Request.CreateResponse(HttpStatusCode.OK, "Success");
        }



        //------------------------------CRUD------------------------------//

        public void createLocation(CP_Location location)
        {
            using (IDataContext ctx = DataContext.Instance())
            {
                var rep = ctx.GetRepository<CP_Location>();
                rep.Insert(location);
            }
        }
    }
}

Here is my object

这是我的目标

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Spatial;
using System.Data.Entity;

using DotNetNuke.ComponentModel.DataAnnotations;
using DotNetNuke.Data;
using DotNetNuke.Data.PetaPoco;

namespace DotNetNuke.Modules.GeoLocations
{
    [TableName("CP_Locations")]
    [PrimaryKey("LocationId", AutoIncrement = true)]
    public class CP_Location
    {
        public int LocationId { get; set; }
        public string LocationType { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }
        public float Long { get; set; }
        public float Lat { get; set; }
        public DbGeography GeoCode { get; set; }
    }

}

I am passing in the Long and Lat from the client side from a Google map which gets the coords from a mouse click

我从客户端通过Long和Lat从Google地图传递，通过鼠标点击获取坐标

In my database if I were to directly write an insert or update using the following, it will work.

在我的数据库中，如果我使用以下内容直接编写插入或更新，它将起作用。

geography:: STGeomFromText('POINT(-121.527200 45.712113)' , 4326);

What might be the reason?

可能是什么原因？

-- though I would include a screen shot of the object

1 个解决方案

[TableName("CP_Locations")]
[PrimaryKey("LocationId", AutoIncrement = true)]
public class CP_Location
{
    public int LocationId { get; set; }
    public string LocationType { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public float Long { get; set; }
    public float Lat { get; set; }
    [IgnoreColumn]
    public DbGeography GeoCodeObj { 
        get { return DbGeography.FromText(GeoCode); }
        set { GeoCode = value.AsText(); }
    }

    public string GeoCode { get; protected set; }
}
