Dear ratam:

　　　　I write the information about the problem with richTextFormat:

　　   I am developing a GUI for MongoDB with your C# Driver.

      I create a environment to simulate Replset:

 

Shard1:

cd C:\runmongo\bin

mongod --shardsvr  --port 10001 --dbpath  C:\mongodb\shard1 --replSet set1 --rest 

Shard2:

cd C:\runmongo\bin

mongod --shardsvr  --port 10002 --dbpath  C:\mongodb\shard2 --replSet set1 --rest 

Shard3:

cd C:\runmongo\bin

mongod --shardsvr  --port 20001 --dbpath  C:\mongodb\shard3 --replSet set2 --rest 

Shard4:

cd C:\runmongo\bin

mongod --shardsvr  --port 20002 --dbpath  C:\mongodb\shard4 --replSet set2 --rest 

Config:

cd C:\runmongo\bin

mongod --configsvr --port 30001 --dbpath  C:\mongodb\config1 --rest 

Route:

cd C:\runmongo\bin

mongos --configdb localhost:30001

     I Create 2 Sets of ReplSet.

     I think the relpsetname is a property of MongoSrv,So when a new mongosvr is register to system,

the replsetName is save in config file.

    Now I user MongoSetting to create MongoService Instance:

                    

if (config.ReplSetName != 

string.Empty)

                    {

                        mongoSvrSetting.ReplicaSetName = config.ReplSetName;

                    }

                    MongoServer masterMongoSvr = 

new MongoServer(mongoSvrSetting);

                    _mongoSrvLst.Add(config.HostName, masterMongoSvr);

Then when I want to get ReplicaSetName, it is always null.

I have initReplset with replSetInitiate command.

 

By the way,ConnectionMode is setting with Direct (I have tried with ReplSet,but the replsetname is still null)

                    mongoSvrSetting.ConnectionMode = ConnectionMode.Direct;

                    mongoSvrSetting.SlaveOk = config.IsSlaveOk;
