$(function(){$('#lbtEnviar').click(function(){varfileUpload=$("#upFoto").get(0);
            var files = fileUpload.files;
            var test = new FormData();
            for (var i = 0; i < files.length; i++) {
                test.append(files[i].name, files[i]);
            }
            $.ajax({
                url: "UploadArquivo.ashx",
                type: "POST",
                contentType: false,
                processData: false,
                data: test,
                // dataType: "json",
                success: function (result) {
                    alert(result);
                },
                error: function (err) {
                    alert(err.statusText);
                }
            });
        });
    })

C # snippet that receives the file:

public void ProcessRequest(HttpContext context)
        {
            try
            {
                if (context.Request.Files.Count > 0)
                {
                    HttpFileCollection files = context.Request.Files;
                    for (int i = 0; i < files.Count; i++)
                    {
                        HttpPostedFile file = files[i];
                        string fname;
                        if (HttpContext.Current.Request.Browser.Browser.ToUpper() == "IE" || HttpContext.Current.Request.Browser.Browser.ToUpper() == "INTERNETEXPLORER")
                        {
                            string[] testfiles = file.FileName.Split(new char[] { '\' });
                            fname = testfiles[testfiles.Length - 1];
                        }
                        else
                        {
                            fname = file.FileName;
                        }

                        string pathToSave = "D:\Msik_Arquivos" + "\" + fname;
                        file.SaveAs(pathToSave);
                    }
                }
                context.Response.ContentType = "text/plain";
                context.Response.Write("File Uploaded Successfully!");
            }
