SqlGeography.STGeomFromText 创建多边形时抛出异常

Question

在创建 Polygon 期间它会抛出执行。我正在使用库 Microsoft.SqlServer.Types 最新版本 160。

polyText = "POLYGON ((

创建

SqlGeography.Point

它工作正常没有问题，只创建读取插入多边形，因为它会抛出错误。

Answer 1

我设法通过将

Microsoft.SqlServer.Types

降级到版本 14 来解决此异常

Answer 2

正在加载的 SqlServerSpatial160.dll 库必须针对与 Microsoft.SqlServer.Types.dll 相同的体系结构进行编译（除了绑定重定向之外）。

此nupkg：https://www.nuget.org/packages/Microsoft.SqlServer.Types/包含文件夹

runtimes\win-x64\native\

和

runtimes\win-x86\native\

，它们都包含SqlServerSpatial160.dll

就我而言，我必须显式复制正确的 DLL 并使用 .targets 手动导入它，因为我的 Microsoft.SqlServer.Types 是 32 位的，而它出于某种原因尝试加载 SqlServerSpatial160 64 位版本。

在调试器中，我可以看到错误的图像格式异常，该异常被

SQL Server Spatial library could not be loaded.

错误掩盖。
