我有以下类O.R.M.实体框架INSERT语句冲突与外键约束的例外
public class Employee
{
public Guid Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Gender { get; set; }
public int Salary { get; set; }
public string PhoneNumber { get; set; }
public Guid DepartmentId { get; set; }
public virtual Department Department { get; set; }
public int Deleted { get; set; }
public bool IsDeleted()
{
return this.Deleted == 1 ? true : false;
}
public void MarkAsDeleted()
{
this.Deleted = 1;
}
public string GetFullName()
{
return this.FirstName + " " + this.LastName;
}
}
public class Department
{
public Department()
{
this.Employees = new List<Employee>();
}
public Guid Id { get; set; }
public string Name { get; set; }
public virtual List<Employee> Employees { get; set; }
public int Deleted { get; set; }
public bool IsDeleted()
{
return this.Deleted == 1 ? true : false;
}
public void MarkAsDeleted()
{
this.Deleted = 1;
}
public void AddEmployee(Employee employee)
{
this.Employees.Add(employee);
}
public void RemoveEmployee(Employee employee)
{
this.Employees.Remove(employee);
}
}
我想创建一个一对多的关系,在我的配置我有这个
下面的代码[modelBuilder.Entity<Department>()
.HasMany(l => l.Employees).
WithRequired(r => r.Department).
HasForeignKey(r => r.DepartmentId);
但它抛出一个异常
INSERT语句冲突与外键约束\ FK_dbo.Employees_dbo.Depa rtments_DepartmentId。冲突发生在数据库\ Entities \,表\ dbo.Departments \中,列Id
任何人都可以帮我吗?谢谢
