我正在使用Ajax文件上传器，它可以将多个文件上传到数据库。但我面临一些问题。当我使用任何母版页时，只会上传多个所选文件中的1个文件，并且不会上传所有剩余文件。
但是当我不使用任何母版页时，它的工作正常。
我不确定此处提供的代码，请告诉我应提供哪些代码（CS或ASPX）以供参考。
cs code：
protected void UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
{
try
{
string path = Server.MapPath("~/Uploads/") + e.FileName;
string ext = e.FileName.Split('.')[1];
AjaxFileUpload1.SaveAs(path);
string content_type="";
object readOnly = false;
object missing = System.Reflection.Missing.Value;
//WdProtectionType typ = WdProtectionType.wdNoProtection;
Word.Application app = new Word.Application();
if ((ext == "doc") || (ext == "docx") || (ext == "DOC") || (ext == "DOCX"))
{
content_type = "application/vnd.ms-word";
//Word.Document tempDoc = app.Documents.Open(path);
//// tempDoc.TrackRevisions = true;
//// tempDoc.Protect(typ, ref missing, ref password, ref missing, ref missing);
//tempDoc.Close(ref Nothing, ref format, ref Nothing);
}
if ((ext == "xlsx") || (ext == "xls") || (ext == "XLSX") || (ext == "XLS"))
{
content_type = "application/vnd.ms-excel";
//Excel.Application ex_APP = new Excel.Application();
//Excel.Workbook book = ex_APP.Workbooks.Open(path);
//// book.KeepChangeHistory = true;
//// book.HighlightChangesOnScreen = true;
//book.Close(Nothing, path, Nothing);
}
if ((ext == "pdf") || (ext == "PDF"))
{
content_type = "application/pdf";
}
if ((ext == "txt") || (ext == "TXT"))
{
content_type = "text/plain";
}
if ((ext == "jpg") || (ext == "jpeg") || (ext == "JPG") || (ext == "JPEG"))
{
content_type = "image/jpeg";
}
byte[] imageBytes = File.ReadAllBytes(System.Web.HttpContext.Current.Server.MapPath("~/Uploads/") + e.FileName);
GENERIC.db.Document_Master_insert(e.FileName.ToString(), 1, imageBytes, "abcd_001", ext, System.DateTime.Now, "0.1", content_type);
//BindGridviewData();
File.Delete(Server.MapPath("~/Uploads/") + e.FileName);
}
catch (Exception ex)
{
throw;
}
}

在我的项目中，我这样做，我认为这会对你有所帮助。它在下面
首先添加以下参考文件
在aspx页面
<script src="js/jquery-1.3.2.min.js" type="text/javascript"></script>
<script type="text/javascript" src="js/jquery.uploadify.js"></script>
<script type="text/javascript">
$(function () {
$("[id*=FileUpload1]").fileUpload({
'uploader': 'js/uploader.swf',
'cancelImg': 'images/cancel.png',
'buttonText': 'Attach Files',
'script': 'UploadFile.ashx',
'folder': 'uploads',
'multi': true,
'auto': true,
'onSelect': function (event, ID, file) {
$("#attachedfiles tr").each(function () {
if ($("td", this).eq(0).html() == file.name) {
alert(file.name + " already uploaded.");
$("[id*=FileUpload1]").fileUploadCancel(ID);
return;
}
});
},
'onComplete': function (event, ID, file, response, data) {
$("#attachedfiles").append("<tr><td>" + file.name + "</td><td><a href = 'javascript:;'>Cancel</a></td></tr>");
}
});
});
$("#attachedfiles a").live("click", function () {
var row = $(this).closest("tr");
var fileName = $("td", row).eq(0).html();
$.ajax({
type: "POST",
url: "SendEmail.aspx/RemoveFile",
data: '{fileName: "' + fileName + '" }',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function () { },
failure: function (response) {
alert(response.d);
}
});
row.remove();
});
</script>
然后我创建一个处理程序。此代码将帮助您上传恶意文件
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
context.Response.Expires = -1;
try
{
HttpPostedFile postedFile = context.Request.Files["Filedata"];
string savepath = "";
string tempPath = "";
tempPath = System.Configuration.ConfigurationManager.AppSettings["FolderPath"];
savepath = context.Server.MapPath(tempPath);
string filename = postedFile.FileName;
if (!Directory.Exists(savepath))
Directory.CreateDirectory(savepath);
postedFile.SaveAs(savepath + @"\" + filename);
context.Response.Write(tempPath + "/" + filename);
context.Response.StatusCode = 200;
}
catch (Exception ex)
{
context.Response.Write("Error: " + ex.Message);
}
}
