i am messing around with file uploading using asp.net mvc-5 HttpPostedFileBase
but it is showing me HttpPostedFileBase is null after i am selecting the image
here is my code
<input type="file" title="search image" file-model="profileimage" id="allfilepath" name="file" />
<button type="submit" class="btn btn-primary col-sm-5">
<span class="glyphicon glyphicon-plus"></span>
</button>
and my controller
[HttpPost]
public ActionResult insert(HttpPostedFileBase file, quotationcompany quotecomp)
{
var allowedExtensions = new[] {
".Jpg", ".png", ".jpg", "jpeg"
};
if (file == null)
{
ViewBag.message = "Please Select Image";
return View();
}
else {
ViewBag.message = "Image Uploaded Successfully";
return View();
}
}
if (file == null)(on this line (
file
) is showing me null after i am uploading png image)
what is wrong in this code?
回答1:
Check Form Attributes
A common mistake people make is missing the following part in the form tag:
<form enctype="multipart/form-data">
</form>
Also in MVC your form structure could look something like this
@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new { @enctype = "multipart/form-data", @id = "myForm", @role="form" }))
