File upload in ASP.NET MVC

 

File upload in ASP.NET MVC

 

Here is a sample for handling upload of a file, In your MVC application. In this sample i used the Dialog box of JQuery, where user will select the file and will click upload


<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">    

<h2>Files uploaded to server</h2>    

<div id="dialog" title="Upload files">        
    <% using (Html.BeginForm("Upload", "File", FormMethod.Post, new { enctype = "multipart/form-data" }))
    {%><br />
        <p><input type="file" id="fileUpload" name="fileUpload" size="23"/> ;</p><br />
        <p><input type="submit" value="Upload file" /></p>        
    <% } %>    
</div>
<a href="#" onclick="jQuery('#dialog').dialog('open'); return false">Upload File</a>
</asp:content>

Then we have to handle this request in the respective controller which is specified in BeginForm of our above code (FileContoller) and action name (Upload). Following will be our code in the FileController Controller for the Upload action


public void Upload()
{
foreach (string inputTagName in Request.Files)
{
HttpPostedFileBase file = Request.Files[inputTagName];
if (file.ContentLength > 0)
{
string filePath = Path.Combine(HttpContext.Server.MapPath("../Uploads")
, Path.GetFileName(file.FileName));
file.SaveAs(filePath);
}
}

RedirectToAction("Index", "File");
}
