Question

I am trying to implement a simple file upload, but having some troubles. When I hard-code the path it works fine. But for some reason, when I try to use a file upload, the controller name is being appended to the path

Hard coded path (what I’m trying to get):

@"C:\Users\Scott\Documents\The Business\MasterSpinSite\MasterSpin\MasterSpin\LOADME.txt"

Path I am getting an exception with (notice the “appz” controller name):

C:\Users\Scott\Documents\The Business\MasterSpinSite\MasterSpin\MasterSpin\appz\LOADME.txt'

My Controller

public ActionResult Load(spinnerValidation theData, HttpPostedFileBase file)
    {

        if (file.ContentLength > 0)
        {

            string filePath = Request.MapPath(file.FileName);

            string input = System.IO.File.ReadAllText(filePath);
            string[] lines = Regex.Split(input, "#!#");
           // ...... do stuff

        }

My View

<form action="" method="post" enctype="multipart/form-data">

  <label for="file">Filename:</label>
  <input type="file" name="file" id="file" />

<input type="submit" value="LOAD ME!">

 </form>

What could be causing this behavior ?

Answer 1

try this:

public ActionResult Load(spinnerValidation theData, HttpPostedFileBase file)

    if (file.ContentLength > 0)
    {
        var filePath = System.IO.Path.GetFileName(file.FileName);
        using (System.IO.StreamReader sr = new System.IO.StreamReader(filePath))
        {
            var input = sr.ReadToEnd();
            var lines = Regex.Split(input, "#!#");
        }
    }
}

(bug) System.IO.Path.GetFileName(file.FileName) return the name of file

Edit

change System.IO.Path.GetFileName(file.FileName) for Server.MapPath(file.FileName)

public ActionResult Load(spinnerValidation theData, HttpPostedFileBase file)

    if (file.ContentLength > 0)
    {
        var filePath = Server.MapPath(file.FileName);
        using (System.IO.StreamReader sr = new System.IO.StreamReader(filePath))
        {
            var input = sr.ReadToEnd();
            var lines = Regex.Split(input, "#!#");
        }
    }
}

Edit II

or copy to diferent path:

public ActionResult Load(spinnerValidation theData, HttpPostedFileBase file)

    if (file.ContentLength > 0)
    {
        var fileName = System.IO.Path.GetFileName(file.FileName);
        var fileUpload = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);
        file.SaveAs(fileUpload);
        if (System.IO.File.Exists(fileUpload)) 
        {
            using (System.IO.StreamReader sr = new System.IO.StreamReader(fileUpload))
            {
                var input = sr.ReadToEnd();
                var lines = Regex.Split(input, "#!#");
            }
        }
    }
}
