sql-server - ServiceStack OrmLite 未检索 SqlGeography 字段

Question

我已按照此处的说明将 SqlGeography 类型与 ServiceStack OrmLite v. 4.0.56 结合使用: https://github.com/ServiceStack/ServiceStack.OrmLite/wiki/SQL-Server-Types

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

(不是网络应用程序)

这是我的 DataModel 类:

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

当我使用OrmLite检索这些记录时，所有LatLong均为空，但数据库中有数据:

我的测试只是检索所有记录:

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

看起来安装 nuget 包时出现错误，但是，没有运行时错误(我在安装 nuget 包时一直收到此错误):

如果这些安装问题仍然存在，您可以尝试删除 NuGet /packages 文件夹和 clearing your NuGet cache因此，下次安装 ServiceStack.OrmLite.SqlServer.Converters 时，它将再次从 NuGet 重新下载所有包。

要使用 SQL Server 特定类型，您需要使用 SqlServer2012Dialect.Provider 并在连接字符串上指定您使用的是 SQL Server 2012，例如:

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);

然后您将能够正常使用 SQL Server 特定类型，例如这个例子:

db.DropAndCreateTable<BusinessEntity>();

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

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

打印出填充的SqlGeography记录:

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