如何使用C＃，Entity Framework和SQL Server 2008读/写地理数据？

Question

I have a form from which the user will be able to enter the latitude and longitude of a certain point on the map. The data will be input as string values. I did some research and found out from various sources that the Entity Framework doesn't support geography data types.

• How can I parse and/or save the string data to a geography column in a database?
• How can I access it and reparse it as string once it is stored?

Thanks in advance!

In fact Entity Framework 5 components that are shipped with .NET Framework 4.5 do support spatial types. Take a look at this walkthrough .

EDIT With EF6 you can use spatial types on both .NET Framework 4 and .NET Framework 4.5
