使用C＃在mongodb中按ID字段删除文档

Question

I am trying to delete the document by id, which is of type ObjectId, I do have converted the string to ObjectId and passed as parameter to remove from collection, but I am not able to delete the record.

I don't know what is the actuall reason behind, Looking for solution, below is my code sample:

 public void DeleteRecords(string objectID)
        {
            try
            {
                // Create server settings to pass connection string, timeout, etc.
                MongoServerSettings settings = new MongoServerSettings();
                settings.Server = new MongoServerAddress("localhost", 27017);
                // Create server object to communicate with our server
                MongoServer server = new MongoServer(settings);

                MongoDatabase myDB = server.GetDatabase("DemoMongoDB");

                MongoCollection<BsonDocument> records = myDB.GetCollection<BsonDocument>("Records");
                //var query = Query<Records>.EQ(fd => fd._id, ObjectId.Parse(name));
                var query = Query<Records>.EQ(e => e._id, new BsonObjectId(objectID));
                records.Remove(query);

            }
            catch (Exception ex)
            {

            }
        }

Answer 1

Try below code, and see whether is working?

var query = Query.EQ("_id", new BsonObjectId("objectID"));

Or

var query = Query.EQ("_id", name);
records.Remove(query);

Answer 2

Finally, This worked for me, without converting the string to object id and pass as a parameter as a string itself.

var query = Query.EQ("_id", objectID);
records.Remove(query);
