SQL Server 2008中的空间数据/地理，OR映射器和C＃

[英]Spatial data/Geography in SQL Server 2008, OR mappers and C#

原文 2009-12-28 00:41:02 1 1 c#/ entity-framework/ sql-server-2008/ spatial

I'm developing an application in C# that will use and store geographic locations using the data type "Geography" in SQL Server 2008. I was planning to use the Entity Framework but soon discovered it lacks support for spatial data. 我正在使用SQL Server 2008中的数据类型“Geography”在C＃中开发一个使用和存储地理位置的应用程序。我计划使用实体框架但很快发现它缺乏对空间数据的支持。 Does anyone have experience with or know of other OR mappers with spatial support? 有没有人有空间支持的其他OR映射器的经验或知道？

The system will have few writes and many reads of geographical data. 该系统将具有很少的写入和许多地理数据读取。 What is a good/preffered way to read/write spatial/Geography data from C#? 从C＃读取/写入空间/地理数据的好/优先方法是什么？
