ServiceStack OrmLite不检索SqlGeography场

Question

我已经按照指示在这里使用SqlGeography类型的ServiceStack OrmLite v 4.0.56： https://github.com/ServiceStack/ServiceStack.OrmLite/wiki/SQL-Server-Types

SqlServerTypes.Utilities.LoadNativeAssemblies(AppDomain.CurrentDomain.BaseDirectory); 
SqlServerConverters.Configure(SqlServer2012Dialect.Provider); 

（而不是Web应用程序）

这里是我的DataModel的类：

[DataContract] 
[Schema("dbo")] 
public class BusinessEntity 
{ 
    [DataMember, PrimaryKey, AutoIncrement] 
    public Int16 BusinessEntityId { get; set; } 
    ... 
    [DataMember] 
    public SqlGeography LatLong { get; set; } 
} 

当我检索使用OrmLite这些记录，所有的LatLong为null，但有数据数据库：

我的测试是简单地检索所有记录：

return Db.Select<DataModel.dbo.BusinessEntity>(); 

它看起来像安装的NuGet包时发生了错误，但是，没有运行时错误（我一直安装nuget包时出现此错误）：

========== Finished ========== 

如果这些安装问题仍然存在，你可以尝试删除你的NuGet /packages文件夹和clearing your NuGet cache所以下次你安装ServiceStack.OrmLite.SqlServer.Converters它将再次从NuGet重新下载所有软件包。

使用SQL Server特定类型的，你需要使用SqlServer2012Dialect.Provider，还可以指定你使用SQL Server 2012中的连接字符串，如：

SqlServerConverters.Configure(SqlServer2012Dialect.Provider); 

var dbFactory = new OrmLiteConnectionFactory(
    "Server=localhost;Database=test;User Id=test;Password=test;Type System Version=SQL Server 2012", 
    SqlServer2012Dialect.Provider); 

然后您就可以使用正常的SQL Server特定类型，例如下面这个例子：

db.DropAndCreateTable<BusinessEntity>(); 

db.Insert(new BusinessEntity 
{ 
    BusinessEntityId = 1, 
    LatLong = SqlGeography.Point(40.6898329, -74.0452177, 4326) 
}); 

db.Select<BusinessEntity>().PrintDump(); 

打印出人口SqlGeography记录：

[ 
     { 
       BusinessEntityId: 1, 
       LatLong: 
       { 
         IsNull: False, 
         STSrid: 4326, 
         Lat: 40.6898329, 
         Long: -74.0452177, 
         Z: Null, 
         M: Null, 
         HasZ: False, 
         HasM: False 
       } 
     } 
]
