我是 asp .net mvc 4.0 的新手。我给了模型。我不知道如何为模型创建视图。我在IList JournalEntries 遇到问题。我能做的其他条目。

public class Journal : BaseClass
{
    public virtual string VoucherNo { get; set; }
    public virtual DateTime VoucherDate { get; set; }
    public string VoucherDateView {
        get
        {
            return VoucherDate.ToShortDateString();
        }
    }
    public IList<JournalEntry> JournalEntries { get; set; }
    public IList<Ledger> Accounts { get; set; }
    public double TotalAmount
    { 
        get 
        { 
            double sum = 0;
            if (JournalEntries != null && JournalEntries.Count>0)
            foreach (var journal in JournalEntries)
                sum = journal.Principal + journal.Interest+sum;
            return sum;
        } 
    }
}

我试过下面的视图，但添加条目不起作用。

    @model Sms.CoreSociety.Journal

    @{
    ViewBag.Title = "Create";
    }
    @{
    string data = new     System.Web.Script.Serialization.JavaScriptSerializer().Serialize(Model);
    }

    <script type="text/javascript">
    $(document).ready(function () {
        $('#document').validate();
        $("#VoucherDate").mask("99/99/9999", { placeholder: " " });
        function entryVm(entries) {
                var self = this;

                self.entryList = ko.observableArray(entries);
                self.entry = ko.observable();
                self.rowClick = function(entry1) {
                                                    alert("Delete alert");
                                                    self.dispatchList.remove(entry1);
                                                };
                self.addEntry = function() {
                                            alert("Add alert");
                                            this.entryList.push({ AccountName_AccountHead:     "", DebitCredit: "", Principal: "0.0", Interest: "0.0", Narration: ""});
                                            };

            }

            var models = @Html.Raw(Json.Encode(Model.JournalEntries)) ;
            ko.applyBindings(new entryVm(models));

    });

视图不是从模型中生成的。您需要 Controller Action 方法将模型传递给 View。

public ActionResult()
{
 var model = new Journal
  {
   //**define here value of model's properties, that you need in View
   }

return View(model);
}

编辑：添加后。我会把它分成两部分。创建 ViewModel 并将其从 View 传递给 Controller。

public JurnalViewModel
{
public Journal journal {get; set;}
public IList<JournalEntry> JournalEntries {get; set;}
}

比在模型中的Create action第一次创建journal和 foreach 之后JournalEntries创建新的JournalEntry。

已编辑 2对您的评论。快速示例：

 [HttpPost]
 public ActionResult Create (JurnalViewModel model)
{
 var journal = new Journal();
 db.Journals.Add(journal);
 journal.name = model.journal.name
 .....
//**some code
db.SaveChanges()

  foreach(var item in model.JournalEntries )
{
  var entry = new JournalEntry()
  db.JournalEntries .Add(entry);
  entry.property = item.property;
  ....
  //**some code
  db.SaveChanges()
 }
}

右键单击控制器内的 Action 方法，然后单击添加视图，然后选中创建强类型视图复选框，然后从显示的对话框中的下拉列表中选择所需的模型

您的问题是您没有 JournalEntries 的类构造函数。

public Journal()
{
    JournalEntries = new List<JournalEntry>();
    Accounts = new List<Ledger>();
}
