这是我的 View 模型
public class FaultTypeViewModel
{
[HiddenInput(DisplayValue = false)]
public int TypeID { get; set; }
[Required(ErrorMessageResourceType = typeof(AdministrationStrings), ErrorMessageResourceName = "FaultTypeNameRequired")]
[Display(ResourceType = typeof(AdministrationStrings), Name = "FaultTypeName")]
public string TypeName { get; set; }
[Display(ResourceType = typeof(AdministrationStrings), Name = "FaultTypeDescription")]
[DataType(DataType.MultilineText)]
public string TypeDescription { get; set; }
[Display(ResourceType = typeof(AdministrationStrings), Name = "FaultTypeImageFile")]
public HttpPostedFileBase TypeImageFile { get; set; }
[HiddenInput(DisplayValue = false)]
public string TypeImageURL { get; set; }
}
注意我有一个“TypeImageFile”HttpPostedFileBase
我希望模型绑定(bind)器将该属性从表单绑定(bind)到模型传递给 Controller ,但我只是不断收到 null。
这是 View 中的相关代码:
@using (Html.BeginForm("AddFaultType","Administration", FormMethod.Post))
{
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">
×</button>
<h3 id="myModalLabel">@SharedStrings.Add @SharedStrings.FaultType</h3>
</div>
<div class="modal-body">
@Html.ValidationSummary(true)
<div class="editor-label">
@Html.LabelFor(model => model.TypeName)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.TypeName)
@Html.ValidationMessageFor(model => model.TypeName)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.TypeDescription)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.TypeDescription)
@Html.ValidationMessageFor(model => model.TypeDescription)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.TypeImageFile)
</div>
<div class="editor-field">
<input type="file" name="TypeImageFile" id="TypeImageFile" />
</div>
</div>
<div class="modal-footer">
<input type="submit" value="@SharedStrings.Add" class="btn btn-primary" />
@Html.ActionLink(SharedStrings.Cancel, "Index", "Administration", null, new { Class = "btn", data_dismiss = "modal", aria_hidden = "true" })
</div>
}
这是 Controller :
[HttpPost]
public ActionResult AddFaultType(FaultTypeViewModel i_FaultToAdd)
{
var fileName = Path.GetFileName(i_FaultToAdd.TypeImageFile.FileName);
var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);
i_FaultToAdd.TypeImageFile.SaveAs(path);
return RedirectToAction("Index");
}
最佳答案
确保您已设置 enctype
在您的表格上注明 multipart/form-data
如果您希望能够上传文件,请在您的表单上:
@using (Html.BeginForm("AddFaultType", "Administration", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
...
}
