Question

我使用此代码显示Persian date：

这是我的模特：

public class PaperOrder
{

    public int PaperOrderId { get; set; }

    [DisplayName("سفارش دهنده")]
    public string CustomerName { get; set; }

    [DisplayName("گیرنده")]
    public string ReceiverName { get; set; }

    [DisplayName("شماره تماس")]
    public string Tel { get; set; }


    [DisplayName(" نوع سفارش")]
    public String OrderType { get; set; }


    [DisplayName("تعداد")]
    public String Count { get; set; }

    [DisplayName("وضعیت سفارش")]
    public OrderStatus OrderStatus { get; set; }

    [DisplayName("تاریخ ارسال سفارش")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
    public DateTime? StartDate { get; set; }

    [DisplayName("تاریخ اتمام سفارش")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
    public DateTime? CompleteDate { get; set; }
}

我的edit.cshtml

的一部分

  <div class="form-group">
        @Html.LabelFor(model => model.StartDate, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.TextBoxFor(model => model.StartDate, new { @id = "pcal1", @class = "pdate form-control" })
            @Html.ValidationMessageFor(model => model.StartDate, "", new { @class = "text-danger" })
        </div>
    </div>

    <div class="form-group">
        @Html.LabelFor(model => model.CompleteDate, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.TextBoxFor(model => model.CompleteDate, new { @id = "pcal2", @class = "pdate form-control" })
            @Html.ValidationMessageFor(model => model.CompleteDate, "", new { @class = "text-danger" })
        </div>
    </div>

每件事情都很好，但是当我想在我的应用程序中只显示日期时，它并没有正确显示。
例如，当我想在输入中只显示日期时，它会像这样显示它（看零）： enter image description here

Answer 1

在视图中替换代码：

@Html.TextBoxFor(model => model.StartDate, new { @id = "pcal1", @class = "pdate form-control" })

以下内容：

@Html.TextBox("StartDate", Model.StartDate.Value.ToShortDateString(), new { @id = "pcal1", @class = "pdate form-control" })

如果没有指定将DateTime值转换为String的特定方法，则会调用方法ToString()来显示时间部分。为避免这种情况，您必须在此情况下指定ToShortDateString()的正确方法。不要忘记检查可能的空引用。

在Shamsi日历中仅显示日期
