在 C# 中使用 MongoDB

按照 MongoDB 官方的教程，使用 Nuget 是最简便的获取 MongoDB driver 的方式。NuGet 是 .NET 的一个包管理器。

高于 2017 的 Visual Studio 自带 NuGet。在 Visual Studio 的搜索框里面搜索 NuGet 就可以搜到。在 NuGet 里面搜索 MongoDB 可以搜到五个包：

• MongoDB.Driver: The new driver. It is mostly free of any legacy code and should be used for all new projects. More documentation can be found in the reference guide.
• MongoDB.Driver.Core: The core of the driver and a dependency of MongoDB.Driver. You will probably not use this package directly. More documentation can be found in the reference guide.
• MongoDB.Driver.GridFS: The GridFS package. More documentation can be found in the reference guide.
• MongoDB.Bson: The BSON layer. It is a dependency of MongoDB.Driver.Core. It may be used by itself. More documentation can be found in the reference guide.
• mongocsharpdriver: The compatibility layer for those upgrading from our 1.x series. This should not be used for new projects. More information can be found in the 1.x documentation;

基本上直接安装 MongoDB.Driver。点击下载即可。
