我想创建一个表单,用户可以在其中编辑个人资料并上传图片,如果他们愿意,这是我的视图
//表单字符串@using(Html.BeginForm("EditProfile","Employee",FormMethod.Post,
new { enctype = "multipart/form-data " }))
//输入HTML <input type="file" name="file" id="file"/>
//提交<input type="submit" name="SubmitBtn" value="SaveProfile" />
<input type="submit" name="SubmitBtn" value="Cancel" />
现在我的控制器
//Profile Modification
[Authorize]
[HttpPost]
public ActionResult EditProfile(employer model, string SubmitBtn,HttpFileCollection file)
{
switch (SubmitBtn)
{
case "SaveProfile":
try
{
if (ModelState.IsValid)
{
//the file is always null
if (file != null)
{
//Function I want to Apply on file
model.logoname = logouploded(file);
return RedirectToAction("Profile", "Employer");
}
return RedirectToAction("EditProfile");
}
//ChangeEmployeeProfile(model);
}
catch (Exception ex)
{
ViewBag.warn = ex.Message;
return View(model);
}
break;
case "Cancel":
return RedirectToAction("index");
}
return View(model);
}
现在无论我上传什么文件,文件总是为空,我也尝试将 HttpFileCollectionBase 作为操作函数中的参数,但文件仍然为空
只是提到员工模型只包含图像文件名,因为我只想将图像名称保存在数据库中。
