Error in uploading a file using jQuery and Asp.Net

Question

A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll when I try to upload a file to server.

$('#But_Upload').click(function () {
            console.log("its working\n");
            var ajaxRequest = $.ajax({
                type: "POST",
                url: "../HANDLERS/Handler1.ashx",
                contentType: false,
                processData: false,
                data: $('#upload').get(0).files.toString(),
                async: true,
                success: function (xhr) {
                    console.log("done");
                }
            });
        });
    });
</script>

My server code in C# handler is

public void ProcessRequest(HttpContext context)
    {
        System.Diagnostics.Debug.Write(context.ToString());
        try
        {
                HttpPostedFile httpPostedFile = context.Request.Files.Get(0);
                var fileSavePath = HttpContext.Current.Server.MapPath("~/upl") + httpPostedFile.FileName;
                httpPostedFile.SaveAs(fileSavePath);
           }
        catch(Exception E)
        {  }
     }

I am getting the exception exactly at httpPostedFile line,I have been fighting with this for donkey age ,pls help.

Try this code. There is an special change here for IE and so It works in all browsers. I guess you are facing the problem in IE only?

HttpPostedFile hpf = TryCast(Context.Request.Files(0), HttpPostedFile);

if ((HttpContext.Current.Request.Browser.Browser.ToUpper() == "IE")) {
    string[] files = hpf.FileName.Split(new char[] {"\\", c});
    MySerializedobject.FileName = files[(files.Length - 1)];
}
else {
    MySerializedobject.FileName = hpf.FileName;
}

string FileType = hpf.ContentType;
string FileExtension = Path.GetExtension(hpf.FileName);
MySerializedobject.FileType = ("." + MySerializedobject.FileName.Split(".")[1]);
MySerializedobject.FileSize = hpf.ContentLength;
MySerializedobject.FileStream = hpf.InputStream;

Use This

public void ProcessRequest(HttpContext context)
    {
        HttpPostedFile postedFile = context.Request.Files[0];
        string savepath = "", tempPath = "";
        context.Response.ContentType = "text/plain";
        tempPath = System.Configuration.ConfigurationManager.AppSettings["YourFilePath"];
        savepath = context.Server.MapPath(tempPath);
        string extension = System.IO.Path.GetExtension(postedFile.FileName);
        string filename = System.IO.Path.GetFileNameWithoutExtension(postedFile.FileName) + extension;
        if (!Directory.Exists(savepath))
        {
            Directory.CreateDirectory(savepath);
        }
        System.IO.File.Delete(savepath + @"\" + filename);
        postedFile.SaveAs(savepath + @"\" + filename);
    }

on script:

$('#But_Upload').click(function () {
    var files = $("#<%=upload.ClientID %>").get(0).files;
    var test = new FormData();
    test.append(files[0].name, files[0]);
    console.log("its working\n");
    var ajaxRequest = $.ajax({
        type: "POST",
        url: "../HANDLERS/Handler1.ashx",
        contentType: false,
        processData: false,
        data: test,
        async: true,
        success: function (xhr) {
            console.log("done");
        }
    });
});
