Question

我按照此处的说明使用ServiceStack OrmLite v.4.0.56的SqlGeography类型： 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都为空，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>();

安装nuget包时看起来有错误，但是没有运行时错误（我在安装nuget包时始终遇到此错误）：

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

如果这些安装问题仍然存在，您可以尝试删除您的NuGet /packages文件夹和clearing your NuGet cache，以便下次安装ServiceStack.OrmLite.SqlServer.Converters时，它会再次从NuGet重新下载所有软件包。

要使用特定于SQL Server的类型，您需要使用SqlServer2012Dialect.Provider并指定您在连接字符串上使用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);

然后您可以正常使用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();

打印出已填充的SqlGeography记录：

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

ServiceStack OrmLite无法检索SqlGeography字段
