使用Xamarin.Forms连接DB问题C＃

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：

{System.EntryPointNotFoundException: mono_get_runtime_build_info

我尝试在此线路上进行连接：

var client = new MongoClient(settings);

没有设置，没有连接字符串，但没有...我能够使用命令提示和db.movie.insert添加文档https://www.tutorialspoint.com/mongodb/mongodb_create_database.htm，但是当我尝试使用C＃驱动程序连接时，就像服务器未运行一样。

请帮忙！谢谢

尝试使用机器的IP，这是Mongo DB的主机。但是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REST的请求发送到您的节点JS应用程序，并在节点JS中将/从/写入/写入DB。这远胜于您在这里实现的目标。您的方法使您的数据处于危险之中。
