Linq2Sql或EF4中的空间数据类型支持 [英] Spatial data types support in Linq2Sql or EF4
问题描述
有人知道(理想情况下带有参考)，VS2010版本的LinqToSQL或EntityFramework v4是否支持对SQL 2008空间数据类型的查询?
Does anyone know (ideally, with a reference), whether the VS2010 release of LinqToSQL or EntityFramework v4 will support queries over the SQL 2008 spatial data types?
推荐答案
在EF 4.0中，您可以结合使用我的提示系列.但是到目前为止，这种黑客攻击还没有得到证实. :(
In EF 4.0 you might be able to hack something together using a combination of custom functions and pretending the spatial types are really Binary types. This is something that I am thinking of mucking around with and trying out and adding to my tips series. But as yet even the hack is unproven. :(
对于直接支持，不幸的是L2S或EF v4都不支持VS2010时间范围内的空间类型.
And as for direct support, unfortunately neither L2S or EF v4 will support spatial types in the VS2010 timeframe.
