任何关于错误的想法将不胜感激。谢谢！

服务器以以下标志启动

mongodb-win32-x86_64-2008plus-ssl-4.0.2\bin\mongod --sslMode disabled --dbpath "C:\Users\foobar\AppData\Local\Temp\sj5ufivo.hgy" --port 27017  --bind_ip 127.0.0.1 --replSet singleNodeReplSet

应用代码

MongoClient client = new MongoClient(@"mongodb://127.0.0.1:{0}/?connect=replicaSet;replicaSet=singleNodeReplSet".Formatted(port));
            var admin = client.GetDatabase("admin");
var replConfig = new BsonDocument(new List<BsonElement>()
            {
                new BsonElement("_id", "singleNodeReplSet"),
                new BsonElement("members", new BsonArray { new BsonDocument { { "_id", 0 }, { "host", "127.0.0.1:27017" } } })
            });
  var commandDocument = new BsonDocument("replSetInitiate", replConfig);
            var replSet = admin.RunCommand<BsonDocument>(commandDocument);

例外

将连接类型更改为直接，将驱动程序更新为 2.7.0 并且可以正常工作！

MongoClient client = new MongoClient(@"mongodb://127.0.0.1:{0}/?connect=direct;replicaSet=singleNodeReplSet".Formatted(port));
