如何使用官方的C＃的驱动程序在MongoDB中使用Update.Set你更新多个领域？ [英] How do you update multiple field using Update.Set in MongoDB using official c# driver?

问题描述

下面code将使我更新的电子邮件，其中姓=约翰和姓氏=李四。你如何在不使用Save（）方法更新电子邮件和电话？

  MongoDB.Driver.MongoServer _ SERVER = MongoDB.Driver.MongoServer.Create（MongoDB的：// localhost的）;
MongoDB.Driver.MongoDatabase _dataBase = _server.GetDatabase（测试）;
MongoDB.Driver.MongoCollection＆LT;人＆GT; _person = _dataBase.GetCollection＆LT;人＆GT;（人）;

//开创全省新的人，并将其插入集合
的ObjectId NEWID = ObjectId.GenerateNewId（）;
人newPerson =新的Person（）;
newPerson.Id = newId.ToString（）;
newPerson.FirstName =约翰;
newPerson.LastName =李四;
newPerson.Email =[e-mail];
newPerson.Phone =8005551222;
_person.Insert（newPerson）;

//更新电话和电子邮件与姓约翰和姓氏母鹿所有记录
MongoDB.Driver.Builders.QueryComplete更改为MyQuery = MongoDB.Driver.Builders.Query.And（MongoDB.Driver.Builders.Query.EQ（名字，约翰），MongoDB.Driver.Builders.Query.EQ（姓氏，Doe的））;
MongoDB.Driver.Builders.UpdateBuilder更新= MongoDB.Driver.Builders.Update.Set（电子邮件，[e-mail]）;

_person.Update（更改为MyQuery，更新）;
 

解决方案

这很简单;），只需添加另一套或一些其他操作到您的更新：

  VAR更新= Update.Set（电子邮件，[e-mail]）
                    。设置（电话，4455512）;
 

The following code will allow me to update the Email where FirstName = "john" and LastName = "Doe". How do you update both Email and Phone without using Save() method?

MongoDB.Driver.MongoServer _server = MongoDB.Driver.MongoServer.Create("mongodb://localhost");
MongoDB.Driver.MongoDatabase _dataBase = _server.GetDatabase("test");
MongoDB.Driver.MongoCollection<Person> _person = _dataBase.GetCollection<Person>("person");

//Creat new person and insert it into collection
ObjectId newId  = ObjectId.GenerateNewId();
Person newPerson = new Person();
newPerson.Id = newId.ToString();
newPerson.FirstName = "John";
newPerson.LastName = "Doe";
newPerson.Email = "[e-mail]";
newPerson.Phone = "8005551222";
_person.Insert(newPerson);

//Update phone and email for all record with firstname john and lastname doe
MongoDB.Driver.Builders.QueryComplete myQuery = MongoDB.Driver.Builders.Query.And(MongoDB.Driver.Builders.Query.EQ("FirstName", "John"),    MongoDB.Driver.Builders.Query.EQ("LastName", "Doe"));
MongoDB.Driver.Builders.UpdateBuilder update = MongoDB.Driver.Builders.Update.Set("Email", "[e-mail]");

_person.Update(myQuery, update);

解决方案

It's very simple ;), just add another set or some else operation to the your update:

 var update = Update.Set("Email", "[e-mail]")
                    .Set("Phone", "4455512");
