Question

仅学习如何使用MongoDB C＃驱动程序，并且想知道为什么“ MongoClient”尝试使用错误的凭据连续重新连接？

如何停止自动连接并处理“ MongoAuthenticationException”，以便用户可以尝试重新登录？

namespace MongoDBConsole
{
internal class Program
{
    public static void Main(string[] args)
    {
        MainAsyc().Wait();

        Console.ReadLine();
    }

    static async Task MainAsyc()
    {
        var pw = "admin";
        var sPwd = new SecureString();
        foreach (var c in pw)
        {
            sPwd.AppendChar(c);
        }

        var settings = new MongoClientSettings()
        {
            Credential = MongoCredential.CreateCredential("admin", "admin", sPwd)
        };

        var client = new MongoClient(settings);
    }
}

}

对于遇到相同问题的任何人，我相信解决方案都是

client.cluster.dispose();
client = null

然后在需要时创建新客户端，例如新凭证

    var settings = new MongoClientSettings()
    {
        Credential = MongoCredential.CreateCredential("admin", "admin", sPwd)
    };

    var client = new MongoClient(settings);
