我的控制器:
[HttpGet]
public ActionResult AddEstablishment()
{
return View("AddEstablishment",new EstablishmentModel());
}
我的模特:
public class EstablishmentModel
{
[Display(Name = "Establishment ID")]
public Guid EstablishmentId { get; set; }
.............
我的AddEstablishment视图:
@Html.TextBoxFor(x => x.EstablishmentId, new { @id = "inputEstGuid", @class = "input input-xlarge", @placeholder = "5C3B1CBC-2574-4E2A-A9FA-A8CA0041AB86" })
结果:
我的文本框预先填充了Guid默认值
00000000-0000-0000-0000-000000000000
我该如何避免?
请注意,我将模型实例传递给视图的原因很明显。

不应该这样吗?
public Guid? EstablishmentId { get; set; }
初次显示视图时,请确保该值为空。

您不需要将模型传递到视图中,如果您不传递它,它将起作用
如果你真的需要,请这样做:
private string _establishmentIdAsString = string.Empty;
[Display(Name = "Establishment ID")]
public string EstablishmentIdAsString
{
get
{
return _establishmentIdAsString;
}
set
{
_establishmentIdAsString = value;
EstablishmentId = new Guid(value);
}
}
