You should not try putting a file into a session variable. Why don't you upload the file to a reserved folder on the server, maybe give it a UID to mark it uniquely, and then simply pass a reference to that file to the other action? — Rob, Mar 28 '14 at 07:41
Dear Robert thanks for your answer but in my app I can't do like you say because this longer code and every time it upload save in server and afther using need delete — user3359460, Mar 28 '14 at 07:49
check if your session variable is not exceeding allowed memory. take a look at this question: http://stackoverflow.com/questions/2843237/asp-net-session-size-limitation — SHM, Mar 28 '14 at 09:31
Why don't you just pass on the content of the file instead of the entire file? This way you will not have to save it and can easily use `TempData` which will be cleaned up once you access the content. And you dont have to worry about the session cleanup and stuff. — Nilesh, Mar 31 '14 at 09:27

Try this. Hope it will work. I din't gave a try.

[HttpPost]
public ActionResult Index(HttpPostedFileBase fil)
{
    if (fil != null && fil.ContentLength > 0)
    {
        // Read bytes from http input stream
        BinaryReader b = new BinaryReader(file.InputStream);
        byte[] binData = b.ReadBytes(file.InputStream.Length);
        string result = System.Text.Encoding.UTF8.GetString(binData);
        Session["doc2"] = result;

    }
    return RedirectToAction("Xmlview");
}

[HttpGet]
public ActionResult Xmlview()
{
    Value model2 = new Value();
    string strall = "";
    string content = Session["doc2"].ToString();
    if (!String.IsNullOrEmpty(content))
    {
        XDocument xml = XDocument.Parse(content);  
        var allElements = xml.Elements();
    }
}

another exception Line 103: XDocument xml = XDocument.Load(content); Illegal characters in path. – user3359460 Mar 28 '14 at 12:52
Check your file content. Generally this error is caused due to not well formed xml document. occurs when any closing tag is missing or node name contains special characters.
