如何将MongoDB驱动程序与C#ASP.NET核心API框架一起使用?

问题描述 投票:5回答:1

我正在尝试创建一个web api应用程序,它将从我已经存在的mongo数据库中获取结果,但是这样做时我收到此错误

Could not load type 'System.Runtime.Remoting.Messaging.CallContext' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

An unhandled exception occurred while processing the request.

我目前有一个针对.NET Core 2.0的ASP.NET Core框架

这是从方法调用中抛出的

var documents = collection.Find(_ => true).ToList();

显然,从我所读到的远程开发还不支持.NET Core,但在MongoDB网站(https://docs.mongodb.com/ecosystem/drivers/csharp/)上,它表示.NET Core 2.0支持驱动程序版本2.4。我已经安装了2.4驱动程序版本,但我似乎无法使用.Find从数据库中取出任何东西。

有没有人有这个解决方案,因为我真的很喜欢我可以在Linux而不是Windows上使用的应用程序?

使用针对.NET Core 2.0的驱动程序绝对是可能的。您只需要确保引用作为以下NuGet包的一部分提供的.NET Standard 1.5程序集:

https://www.nuget.org/packages/MongoDB.Driver

此外,新版本2.5几天前刚刚发布,可能最适合MongoDB 3.6。
