Question

我有以下内容：

MongoClientSettings settings = new MongoClientSettings();
settings.Server = new MongoServerAddress("localhost", 27017);
var client = new MongoClient(settings);

在最后一行我得到了这个：

我尝试过连线：

var client = new MongoClient(settings);

没有设置，有和没有连接字符串但没有...我能够使用命令提示符和db.movie.insert将文档添加到数据库中，如此处所述 https://www.tutorialspoint.com/mongodb/mongodb_create_database.htm但是当我尝试使用C＃驱动程序进行连接时，就像服务器没有运行一样。

请帮忙！并谢谢

尝试使用机器的ip，它是你的mongo db的主机。但我建议您开发一些服务器端代码，例如使用节点js。然后将基于休息的请求发送到您的节点js app，并在节点js中，从/向db读取和写入。这比你想要在这里完成的要好得多。您的方法会使您的数据面临风险。
