Asp.Net文件上传实现Flash进度条代码实例
效果如图
UpFile.Fla
以下是代码片段：
fileRefListener.onSelect = function (fileRefList:FileReferenceList):Void {
uploadBtn.enabled = true;
rePaintProBar("progressBar", 18.0, 50.0);
var list:Array = fileRefList.fileList;
var fileRef:FileReference;
totalBytes = 0;
for(var i:Number = 0; i < list.length; i++) {
fileRef = list[i];
totalBytes += fileRef.size;
txtFilePath.text = fileRef.name;
FileExt = fileRef.type;
}
}
fileRefListener.onCancel = function (fileRef:FileReference):Void {
uploadBtn.enabled = false;
}
fileRefListener.onOpen = function (fileRef:FileReference):Void {
txt_FilePath.label = fileRef.name;
}
fileRefListener.onProgress = function (fileRef:FileReference, bytesLoaded:Number, bytesTotal:Number):Void {
progressBar.mode = "manual";
var temp:Number = bytesLoaded - uploadedBytes2[fileRef.name]
uploadedBytes2[fileRef.name] = bytesLoaded;
uploadedBytes += temp;
progressBar.setProgress(uploadedBytes, totalBytes);
txtUploaded.text = GetSizeType(uploadedBytes);
txtTotal.text = GetSizeType(totalBytes);
}
fileRefListener.onComplete = function (fileRef:FileReference):Void {
filesCompleted++;
if(filesCompleted == totalFiles)
FinishedUpload();
}
fileRefList.addListener(fileRefListener);
browseButn.clickHandler = function () {
fileRefList.browse(allTypes);
}
uploadBtn.clickHandler = function () {
var list:Array = fileRefList.fileList;
var fileRef:FileReference;
if(uploadBtn.label == "上传")
{
browseBtn.enabled = false;
uploadBtn.label = "取消";
totalFiles = list.length;
filesCompleted = 0;
uploadedBytes = 0;
uploadedBytes2 = [];
txtUploadNum.text = "已上传：";
txtFileTotal.text = "文件大小：";
for(var i:Number = 0; i < list.length; i++) {
fileRef = list[i];
fileRef.addListener(fileRefListener);
uploadedBytes2[fileRef.name] = 0;
if(uploadPage != undefined)
fileRef.upload(uploadPage);
}
}
else
{
for(var i:Number = 0; i < list.length; i++) {
fileRef = list[i];
fileRef.cancel();
}
uploadBtn.label = "上传";
browseBtn.enabled = true;
}

UpLoadFile.aspx
以下是代码片段：
string saveToFolder = "/UpFile/";
HttpFileCollection uploadedFiles = Request.Files;
string NewFileName = Session["UpLoadFileName"].ToString();
string Path = Server.MapPath(saveToFolder);
for (int i = 0; i < uploadedFiles.Count; i++)
{
HttpPostedFile F = uploadedFiles[i];
if (uploadedFiles[i] != null && F.ContentLength > 0)
{
string newName = F.FileName.Substring(F.FileName.LastIndexOf("\") + 1);
F.SaveAs(Path + "/" + NewFileName + F.FileName.Substring(F.FileName.LastIndexOf(".")));
}
