把文件二进制数据存入mongodb

               //存入，photoData.Data为二进制文件数据
　　　　　　　　  var db = GetDB();

                string filename = (new GridFSOP()).GridFsSave(photo.Data);

                MongoDB.Bson.BsonDocument doc = new MongoDB.Bson.BsonDocument();

                doc["PhotoID"] = photo.PhotoID;

                doc["Name"] =  photo.Name;

                doc["Description"] =  photo.Description;

                doc["DateTime"] = photo.DateTime;

                doc["filename"] = filename; 

                db["testTable"].Save(doc);
