如何填充GUID属性

本文关键字：GUID 属性 填充 何填充 | 更新日期: 2023-09-27 18:18:44

我正在尝试使用Linq输入GUID。我的插入代码:

  var registration = new Registration
            {
                FirstName = registrationInfo.FirstName,
                LastName = registrationInfo.LastName,
                AddressId = _dbcontext.Addresses.Max(x => x.AddressId),
                Password = registrationInfo.Password,
                EmailAddress = registrationInfo.EmailAddress,
                IsActive = true,
                IsDeleted = false,
                Archived=false,
                DateCreated = DateTime.Now
                GUID = ?
            };

谁能帮我把"?"换成一些有用的代码

如何填充GUID属性

使用内置的工厂方法创建一个新工厂:

GUID = Guid.NewGuid()

顺便说一下，AddressId的setter看起来很奇怪。如果在两者之间创建了另一个地址，则会失败。使用导航属性。

根据您需要的是现有的、空的还是新的Guid，以下选择之一:

Guid.NewGuid();
Guid.Empty;
Guid.Parse("{81a130d2-502f-4cf1-a376-63edeb000e9f}"); // replace with the GUID you need

参见MSDN的GUID结构:http://msdn.microsoft.com/en-us/library/cey1zx63.aspx

试试上面的

 var registration = new Registration
        {
            FirstName = registrationInfo.FirstName,
            LastName = registrationInfo.LastName,
            AddressId = _dbcontext.Addresses.Max(x => x.AddressId),
            Password = registrationInfo.Password,
            EmailAddress = registrationInfo.EmailAddress,
            IsActive = true,
            IsDeleted = false,
            Archived=false,
            DateCreated = DateTime.Now,
            GUID = Guid.NewGuid().ToString()
        };
