我试图使用connectionuri连接到本地mongodb服务器
const string connectionUri1 = "mongodb://Mongodb:27123/admin?retryWrites=true&w=majority";
const string connectionUri2 = "mongodb://admin:password@Mongodb:27017/admin?authMechanism=SCRAM-SHA-1";
const string connectionUri3 = "mongodb://Mongodb:27020/?authMechanism=MONGODB-X509&tls=true&tlsInsecure=true&tlsCertificateKeyFile=/path/to/mongodbca.pem&tlsCAFile=/path/to/mongodbcli.pem&authSource=$external";
var settings = MongoClientSettings.FromConnectionString(connectionUri3);
settings.ServerApi = new ServerApi(ServerApiVersion.V1);
// Create a new client and connect to the server
var client = new MongoClient(settings);
// Send a ping to confirm a successful connection
var result = client.GetDatabase("test").RunCommand<BsonDocument>(new BsonDocument("ping", 1));
Console.WriteLine("Pinged your deployment. You successfully connected to MongoDB!");
Console.WriteLine("Reply: " + result);
connectionUri1 和 2 工作得很好，我可以 ping 并执行读取或写入 对于connectionUri3，它会产生超时错误

我什至没有通过connectionUri3 ping通
我已经用这个连接字符串检查了 mongocompass
mongodb://Mongodb:27020/?tls=true&tlsCAFile=D%3A%5Cca.pem&tlsCertificateKeyFile=D%3A%5Cmongodb.pem&authMechanism=MONGODB-X509&authSource=%24external
并且能够很好地连接
我在linux ubuntu中运行mongodb和程序
