MongoDB的官方C#驅動可以通過這個鏈接得到。鏈接提供了.msi和.zip兩種方式獲取驅動dll文件。C#驅動的基本數據庫連接，增刪改查操作。在使用C#驅動的時候，要在工程中添加"MongoDB.Bson.dll"和"MongoDB.Driver.dll"的引用。同時要在代碼中加入下面兩個using語句。

using?MongoDB.Bson.Serialization.Conventions;
using?MongoDB.Driver;
using?MongoDB.Driver.Linq;
using?System.Text;

注冊常用約定

public?static?void?RigisterConventions(){var?pack?=?new?ConventionPack();//元素名稱序列化成駝峰形式pack.Add(new?CamelCaseElementNameConvention());ConventionRegistry.Register("MyConventions",?pack,?x?=>?true);}
