asp.net-mvc - MVC @html.textbox用于预填充 Guid 默认值

Question

我的 Controller :

 [HttpGet]
 public ActionResult AddEstablishment()
 {     
    return View("AddEstablishment",new EstablishmentModel());
 }

我的模型:

public class EstablishmentModel
{
    [Display(Name = "Establishment ID")]
    public Guid EstablishmentId { get; set; }
    .............

我的 AddEstablishment View :

 @Html.TextBoxFor(x => x.EstablishmentId, new { @id = "inputEstGuid", @class = "input input-xlarge", @placeholder = "5C3B1CBC-2574-4E2A-A9FA-A8CA0041AB86" })

结果:

我的文本框已预填充 Guid 默认值

00000000-0000-0000-0000-000000000000

如何避免它？

请注意，我将模型实例传递给 View 有明显的原因。

Answer 1

这不应该起作用吗？

 public Guid? EstablishmentId { get; set; }

只需确保在最初显示 View 时该值为 null。
