我该怎么做？
我有一个庞大而复杂的集合，如下所示：

"id" : NumberInt(10000),
"BookieId" : NumberInt(1),

"Team1NameId" : null,
"Team2Id" : NumberInt(430),
"Team2NameId" : null,
"EventDateTime" : ISODate("2013-09-14T13:00:00.000+0000"),
"isNew" : true,
"CountryId" : NumberInt(36),
"isCountry" : true,
"isLeague" : true,
"Gameid" : null,
"Reversed" : false,
"eventId" : NumberInt(10000),
"bets" : [
{
"id" : NumberInt(1),
"EventConnectionId" : NumberInt(10000),
"isCorners" : false,
"DateTime" : ISODate("2013-09-10T08:06:43.333+0000"),
"IsLive" : false,
"Team1Score" : null,
"Team2Score" : …我正在使用C#驱动程序将文档插入MongoDB集合,当我调试应用程序时,其中一个字段类型与DateTime我在"FrameTimeStamp"字段中看到服务器时间我将传递给Mongo,这是我的代码:
FrameDocument frameDoc = new FrameDocument();
frameDoc.Frame = imageBA;
frameDoc.EventCodeId = 1;
frameDoc.SesionId = 1;
frameDoc.FrameTimeStamp = DateTime.Now;
frameDoc.ServerUserId = (int)toMongoDt.Rows[0]["ServerUserId"];
frameDoc.TraderId = (int)toMongoDt.Rows[0]["TraderId"];
frameDoc.ActivePick = (int)toMongoDt.Rows[0]["ActivePick"];
frameDoc.TraderName = (string)toMongoDt.Rows[0]["TraderName"];
frameDoc.ServerUserName = (string)toMongoDt.Rows[0]["ServerUserName"];
var mongoCon = "mongodb://127.0.0.1";
MongoClient client = new MongoClient(mongoCon);
var db = client.GetDatabase("Video");
var frameCollection = db.GetCollection<FrameDocument>("Frame");
frameCollection.InsertOne(frameDoc);
在shell中,当我读取数据时,我会看到以下格式: 2016-08-14T06:10:33.295Z并且时间不是服务器时间,它的UTC,我如何强制mongo将DateTime写为我通过了,？

您好，我在 mongoDB 中有一个集合，我只想从中获取部分字段，我创建了一个类，将数据插入到 Mongo
班级代码：
public class FrameDocument
{
public ObjectId _id { get; set; }
public Nullable<System.DateTime> FrameTimeStamp { get; set; }
public Nullable<int> ActivePick { get; set; }
public Nullable<int> TraderId { get; set; }
public Nullable<int> EventCodeId { get; set; }
public byte[] Frame { get; set; }
public int ServerUserId { get; set; }
public int SesionId { get; set; }
public string TraderName { get; set; }
public string ServerUserName { get; set; }

npm install -g ionic
npm install -g cordova
然后我使用命令使用这些创建一个应用程序

但我没有得到有关将 cordova 集成到项目中的问题，如所有教程中所示，
Integrate your new app with Cordova to target native iOS and Android? (y/N)
有人知道那是什么方法吗？
