C# MVC5自定义身份用户

我正在尝试将一些属性添加到我的registerviewmodel中，以便当用户在我的站点上注册时，他们需要添加他们的LastName、FirstMidName、DepotID和DepartmentID。当我试图修改RegisterViewModel创建方法时，出现了错误

DepotID和DepartmentID的RegisterViewModel注册方法错误

public async Task<ActionResult> Register(RegisterViewModel model)
        {
            if (ModelState.IsValid)
            {
                var user = new ApplicationUser { UserName = model.Email, Email = model.Email };

            user.LastName = model.LastName;
            user.FirstMidName = model.FirstMidName;
            user.Depot = model.DepotID;
            //Cannot implicitly convert type 'int' to 'RecreationalServicesTickingSystem.Models.Depot
            user.Department = model.DepartmentID;
            //Cannot implicitly convert type 'int' to 'RecreationalServicesTickingSystem.Models.Department
            user.EnrollmentDate = model.EnrollmentDate;

public class Department
{

    public int DepartmentID { get; set; }

    [StringLength(50, MinimumLength = 1)]
    public string DepartmentName { get; set; }

    public virtual ICollection<User> Users { get; set; }
}

公共课部
{
public int DepartmentID{get；set；}
[StringLength（50，最小长度=1）]
公共字符串DepartmentName{get；set；}
公共虚拟ICollection用户{get；set；}
}

Depot.cs

public class Depot
{

    public int DepotID { get; set; }
    [StringLength(50, MinimumLength = 1)]
    public string DepotName { get; set; }
    public virtual ICollection<User> Users { get; set; }

}

公共级仓库
{
public int DepotID{get；set；}
[StringLength（50，最小长度=1）]
公共字符串DepotName{get；set；}
公共虚拟ICollection用户{get；set；}
}

MVC4中的旧用户类

public class User
{
    public int UserID { get; set; }

    public bool IsAdministrator { get; set; }
    [StringLength(50, MinimumLength = 1)]
    public string LastName { get; set; }
    [StringLength(50, MinimumLength = 1, ErrorMessage = "First name cannot be longer than 50 characters.")]

    [Column("FirstName")]
    public string FirstMidName { get; set; }

    public string FullName
    {
        get { return FirstMidName +" "+ LastName; }
    }
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
    public DateTime EnrollmentDate { get; set; }

    public int DepartmentID { get; set; }
    [ForeignKey("DepartmentID")]
    public virtual Department Department { get; set; }
    public int DepotID { get; set; }
    [ForeignKey("DepotID")]
    public virtual Depot Depot { get; set; }
    public virtual ICollection<Ticket> Tickets { get; set; }


}

公共类用户
{
public int UserID{get；set；}
公共布尔IsAdministrator{get；set；}
[StringLength（50，最小长度=1）]
公共字符串LastName{get；set；}
[StringLength（50，MinimumLength=1，ErrorMessage=“名字不能超过50个字符）。]
[列（“名字”）]
公共字符串FirstMidName{get；set；}
公共字符串全名
{
获取{return FirstMidName+“”+LastName；}
}
[数据类型（DataType.Date）]

公共日期时间注册日期{get；set；}

您正试图将整数值分配给

型号

//Cannot implicitly convert type 'int' to RecreationalServicesTickingSystem.Models.Depot
                user.Department = model.DepartmentID;
//Cannot implicitly convert type 'int' to 'RecreationalServicesTickingSystem.Models.Department
                user.EnrollmentDate = model.EnrollmentDate;

您的型号

ApplicationUser

已

 public int DepartmentID { get; set; }

 [ForeignKey("DepartmentID")]
 public virtual Department Department { get; set; }

正确的代码应为：

//To assign to DepartmentID
  user.DepartmentID = model.DepartmentID;
//OR
//to assign to model's departmentID
  user.Department.DepartmentID = model.DepartmentID;

仓库的情况也一样

//Cannot implicitly convert type 'int' to RecreationalServicesTickingSystem.Models.Depot
                user.Department = model.DepartmentID;
//Cannot implicitly convert type 'int' to 'RecreationalServicesTickingSystem.Models.Department
                user.EnrollmentDate = model.EnrollmentDate;

 public int DepartmentID { get; set; }

 [ForeignKey("DepartmentID")]
 public virtual Department Department { get; set; }

//To assign to DepartmentID
  user.DepartmentID = model.DepartmentID;
//OR
//to assign to model's departmentID
  user.Department.DepartmentID = model.DepartmentID;
