I have a dialog <input type="file" /> and want to get the file name and file path and pass it to my controller ... I can pass a value to my controller as such: post.push(name: 'name', value: 4); — Doctor

in that case their is nothing to do with jquery ...u can pass it through form post or via url (dont know how you achieve this in .net), . If you want you can use ajax(via jquery/javascript) to post your values to server. — ManMohan Vyas

You actually probably won't be able to consistently get the file path, using a <input type="file" /> - for security reasons, a number of browsers display a fake path (C:\fakepath\filename in chrome, for instance) — Chris Carew

so what will be your suggestion Chris? I need to get the file and file name and store them in a database .. the issue is how to pass them from view to my model. — Doctor

Going to post an answer on how to upload a file in MVC3

In your controller, you need a method

[HttpPost]
public ActionResult FileUpload( HttpPostedFileBase file )
{
    byte[] buffer = new byte[file.InputStream.Length];
    file.InputStream.Read( buffer, 0, (int)file.InputStream.Length );
    // You need to have some method of saving the bytes of this file, or use the 
    // file.SaveAs() method to save this to a targeted directory your web server
    // has access to
    YourCode.SaveFile( buffer, file.FileName );
    return View( );
}

And a view set up like so:

@using ( Html.BeginForm("FileUpload","YourControllerName",FormMethod.Post,new { enctype="multipart/form-data"}))
{
    <input type="file" id="file" name="file" />
    <input type="submit" />
}

This will upload the file
