Question

我创建了一个＆＃34;创建＆＃34;包含以下代码的页面。我知道这不是最好的做法，但我不确定如何做到这一点。这是代码：

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "ID,Victim")] Case @case, Person person)
{
    var caseVictims = @case.Victim;
    db.Cases.Add(@case);
    db.SaveChanges();      
    var caseId = @case.ID; //need this
    if (caseVictims != null && caseVictims != "")
    {
        if (caseVictims.Contains(";"))
        { // { "First1,Last1;First2,Last2" }
                string[] victims = caseVictims.Split(';');
                foreach (var victim in victims)
                {
                        person.CaseId = caseId;
                        person.Victim = true;
                        person.FullName = victim;
                        person.Case = null;
                        db.People.Add(person);
                        db.SaveChanges();
                }
        }
        else
        {
                person.CaseId = caseId;
                person.Victim = true;
                person.FullName = caseVictims;
                person.Case = null;
                db.People.Add(person);
                db.SaveChanges();
        }
        return RedirectToAction("Index");
    }
    return View(@case);
}

我希望能够创建一个案例并使用该案例中的信息，例如@case.Victim来填充＆＃34;人员＆＃34;表。现在它正常工作，除了它创建两个＆＃34;案例＆＃34;每次我点击提交。无论有多少受害者＆＃34;就是这种情况。我有。如果我评论＆＃34;受害者＆＃34;部分它只按预期创建一个Case。谢谢你的帮助！

编辑：这是模型

public partial class Person
{
    public int ID { get; set; }
    public int CaseId { get; set; }
    public Nullable<bool> Victim { get; set; }
    public string FullName { get; set; }
    public virtual Case Case { get; set; }
}

public partial class Case
{    
    public int ID { get; set; }
    public string Victim { get; set; }
    public virtual ICollection<Person> People { get; set; }
}

我能够让它按照我想要的方式工作。这是最终的代码：

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "ID,Victim")] Case @case, Case lastCase, Person person)
{
    var caseVictims = @case.Victim;
    lastCase = @case;
    db.Cases.Add(@case);
    db.SaveChanges();      
    var caseId = @case.ID; //need this
    if (caseVictims != null && caseVictims != "")
    {
        if (caseVictims.Contains(";"))
        { // { "First1,Last1;First2,Last2" }
                string[] victims = caseVictims.Split(';');
                foreach (var victim in victims)
                {
                        person.CaseId = caseId;
                        person.Victim = true;
                        person.FullName = victim;
                        person.Case = lastCase;
                        db.People.Add(person);
                        db.SaveChanges();
                }
        }
        else
        {
                person.CaseId = caseId;
                person.Victim = true;
                person.FullName = caseVictims;
                person.Case = lastCase;
                db.People.Add(person);
                db.SaveChanges();
        }
        return RedirectToAction("Index");
    }
    return View(@case);
}

感谢所有人的帮助！：）
