How to upload file to asp .net?

Question

I am looking for a solution on how to send a file using a form to an asp application. I am writing in the asp .net framework MVC Razor.

My form:

<div class="container">
    <div class="col-md-2">
        @using (Html.BeginForm("Data", "Admin", FormMethod.Post, new { encrypte = "multipart/form-data"}))
        {
            <div class="form login-form">
                <label for="username" class="text-info">Wczytaj plik:</label>
                <input type="file" name="file" id="file" />
            </div>
            <div id="register-link" class="text-right">
                <input type="submit" class="btn btn-success" value="Importuj" />
            </div>
            @ViewBag.Message
        }
    </div>
</div>

My controller:


        [HttpPost]
        public ViewResult Data(HttpPostedFile file = null)
        {
            if(file != null && file.ContentLength > 0)
            {
                string path = Path.Combine(Server.MapPath("~/Upload/Data"), Path.GetFileName(file.FileName));
                file.SaveAs(path);
                ViewBag.Message = "Succes";
            }

            return View("AdminDataView", students);
        }

Unfortunately, the above code does not work, am I doing something wrong with it, is there another option to upload the file to asp?

"The above code does not work" is there an error? Are you getting the success message? Did you try to debug? — Jerdine Sabio, Mar 17 '20 at 18:52
I have no errors. So I debugged the code: I load the file and send the form, in the controller the object passed is empty and returns to the original view. — , Mar 17 '20 at 19:22

I think there is a typo and i suggest you that use ActionResult instead of ViewResult.

Defference between ActionResult & ViewResult

the typo is: new { enctype="multipart/form-data"}) not new { encrypte = "multipart/form-data"})

Sample Code:

View

@using(Html.BeginForm("UploadFile","Upload", FormMethod.Post, new { 
enctype="multipart/form-data"}))  
{  
    <div>  
        @Html.TextBox("file", "", new {  type= "file"}) <br />  
        <input type="submit" value="Upload" />  
        @ViewBag.Message  
    </div>     
}

Controller

    [HttpPost]  
    publicActionResultUploadFile(HttpPostedFileBase file)  
    {  
        try  
        {  
            if (file.ContentLength > 0)  
            {  
                string _FileName = Path.GetFileName(file.FileName);  
                string _path = Path.Combine(Server.MapPath("~/UploadedFiles"), _FileName);  
                file.SaveAs(_path);  
            }  
            ViewBag.Message = "File Uploaded Successfully!!";  
            return View();  
        }  
        catch  
        {  
            ViewBag.Message = "File upload failed!!";  
            return View();  
        }  
    }
