在SQL Server和Library项目之间共享空间代码

Question

We use SQL Server CLR in tandem with our webapp, largely for writing complex check constraints.

I need to write a class that works with spatial data, which will be shared between a CLR UDF in SQL Server and Entity Framework.

For Entity Framework, I use DbGeography. How would I represent a spatial type in a CLR UDF? How can I abstract it such that it works in both places?

Answer 1

如MSDN页面上的“ 映射CLR参数数据 ”所述，用于接受GEOGRAPHY / GEOMETRY数据作为SQLCLR对象的输入参数和/或作为返回值/结果集列传递回的类型分别是SqlGeography / SqlGeometry 。
