c# - 'MongoDB.Driver.MongoClient' 不包含 'GetServer' 的定义 ...可以找到类型为 'MongoDB.Driver.MongoClient' 的第一个参数

Question

我正在尝试熟悉从 C# 程序写入 MongoDB。我已经按照 http://mongodb.github.io/mongo-csharp-driver/1.11/getting_started/ 的建议设置了我的代码

我正在尝试运行该程序，但出现此错误“‘MongoDB.Driver.MongoClient’不包含‘GetServer’的定义，并且没有扩展方法‘GetServer’接受‘MongoDB.Driver’类型的第一个参数。可以找到 MongoClient”。我可以得到一些帮助吗？

提前致谢，田.

GetServer() 已被弃用，像这样从客户端检索数据库:

var client = new MongoClient("mongodb://localhost");
var database = client.GetDatabase("test");
var collection = database.GetCollection<Entity>("entities");
