AddRange 未按列出的顺序添加答案

【问题描述】：

我正在用测试数据填充我的数据库，尤其是客户端表。

我注意到，一旦我运行该项目，当它检测到客户端表为空时，它将在初始化例程中使用 AddRange 来添加 100 个客户端。

令我惊讶的是，我注意到系统添加 100 个客户端中的每一个的方式与其在例程中列出的方式不同。

这是它在初始化方法中的写法。

context.Clients.AddRange(
    new Client { ABN = "", Active = true, Activity = true, BankAccount = "4308342999", BankBSB = "083-860", BankName = "NAB", ClientFirstName = "Christine", ClientLastName = "Green", ClientNo = 1001, Company = false, CompanyName = "", CreatorId = 1, DateCreated = new DateTime(2016, 02, 14), Email = "cgreen0@google.com.hk", MobilePhone = "0453439816", Phone = "354492968", Postcode = "3555", StateId = 2, Street1 = "01 Clemons Lane", Suburb = "Kangaroo Flat" },
    new Client { ABN = "", Active = true, Activity = true, BankAccount = "5282113099", BankBSB = "012-857", BankName = "ANZ", ClientFirstName = "Jacqueline", ClientLastName = "Porter", ClientNo = 1002, Company = false, CompanyName = "", CreatorId = 1, DateCreated = new DateTime(2016, 02, 14), Email = "jporter1@prweb.com", MobilePhone = "0454972251", Phone = "354400440", Postcode = "3550", StateId = 2, Street1 = "336 Paget Crossing", Suburb = "Bendigo" },
    new Client { ABN = "", Active = true, Activity = true, BankAccount = "6845784050", BankBSB = "083-625", BankName = "NAB", ClientFirstName = "Norma", ClientLastName = "Alvarez", ClientNo = 1003, Company = false, CompanyName = "", CreatorId = 1, DateCreated = new DateTime(2016, 02, 18), Email = "nalvarez2@telegraph.co.uk", MobilePhone = "0418263652", Phone = "354415087", Postcode = "3556", StateId = 2, Street1 = "9418 Ridge Oak Junction", Suburb = "Eaglenhawk" },.......

请注意，ClientNo 以 1000 开头并递增。但是，当我检查数据库表的数据时，我得到了这个..

ClientNo 以 1000 作为添加范围的一部分，每个客户端都增加 1，但是您可以看到系统以不同的顺序添加每条记录。

如何让 AddRange 按它们在列表中出现的顺序添加记录？

请不要在标题中强行添加标签:) stackoverflow.com/help/tagging 在标签部分添加标签即可

【解决方案1】：

您总是可以将范围添加到列表中并按如下方式对列表进行排序：

var clientList = new List<Client>();
clientList.AddRange(
        new Client { ABN = "", Active = true, Activity = true, BankAccount = "4308342999", BankBSB = "083-860", BankName = "NAB", ClientFirstName = "Christine", ClientLastName = "Green", ClientNo = 1001, Company = false, CompanyName = "", CreatorId = 1, DateCreated = new DateTime(2016, 02, 14), Email = "cgreen0@google.com.hk", MobilePhone = "0453439816", Phone = "354492968", Postcode = "3555", StateId = 2, Street1 = "01 Clemons Lane", Suburb = "Kangaroo Flat" },
        new Client { ABN = "", Active = true, Activity = true, BankAccount = "5282113099", BankBSB = "012-857", BankName = "ANZ", ClientFirstName = "Jacqueline", ClientLastName = "Porter", ClientNo = 1002, Company = false, CompanyName = "", CreatorId = 1, DateCreated = new DateTime(2016, 02, 14), Email = "jporter1@prweb.com", MobilePhone = "0454972251", Phone = "354400440", Postcode = "3550", StateId = 2, Street1 = "336 Paget Crossing", Suburb = "Bendigo" },
        new Client { ABN = "", Active = true, Activity = true, BankAccount = "6845784050", BankBSB = "083-625", BankName = "NAB", ClientFirstName = "Norma", ClientLastName = "Alvarez", ClientNo = 1003, Company = false, CompanyName = "", CreatorId = 1, DateCreated = new DateTime(2016, 02, 18), Email = "nalvarez2@telegraph.co.uk", MobilePhone = "0418263652", Phone = "354415087", Postcode = "3556", StateId = 2, Street1 = "9418 Ridge Oak Junction", Suburb = "Eaglenhawk" });

context.Clients.AddRange(clientList.OrderBy(c => c.ClientNo))
