I saved aspx page as html it worked in my local machine but after published on the server its showing an error that "the access to the path is denied"... I tried giving access permission then also it doesn't work.. can anyone help with it? or else is there any other way to save the page in C# asp.net?...
string url=HttpContext.Current.Request.Url.AbsoluteUri;
string sHtml="";
HttpWebRequest request;
HttpWebResponse response=null;
Stream stream=null;
request=HttpWebRequest)WebRequest.Create(url);
response=(HttpWebResponse)request.GetResponse();
stream=response.GetResponseStream();
StreamReader sr=new StreamReader(stream,System.Text.Encoding.Default);
sHtml=sr.ReadToEnd();
string path=Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string textfilename=TextBox1.Text;
string getpath=path+"\\"+textfilename+".html";
File.WriteAllText(getpath,sHtml);
if(stream!=null)stream.Close();
if(response!=null)response.Close();
Thanks..
If you need to save a file use this to get the application path
Server.MapPath(#"filename.txt");
Try this because when you only write the filename at an web server you are trying to access to a Microsoft.Net folder.
yes make sure the folder you write to has the appropriate privileges. IIS 5 uses ASPNET account, IIS6 uses network service. Just give read/write to the proper account. Is this your dev environment, or a prod environment?
Also, make sure it's pointing to a folder; desktop folder for ASPNET account probably won't exist since ASPNET account isn't a user with a users folder.
I had a similar problem when trying to deploy CSS from a ZIP downloaded from the web. Try right-clicking on the aspx file from windows explorer and checking the file properties. One of the tabs may indicate that the file has been "blocked". If so, there will be a button there to unblock it.

I have an application that allows the user to upload a file (saving it to in a folder located in the wwwroot of the ASPNETCORE application). From here they can make edits to it and then they can choose to export the file as a csv/ xml/ xlsx which downloads the file to the user's 'downloads' folder.
While debugging in Visual Studio this all works fine however when I publish and deploy the application to IIS I am getting the exception
Error saving file C:\windows\system32\config\systemprofile\Downloads(FILE NAME)
Could not find part of the path C:\windows\system32\config\systemprofile\Downloads(FILE NAME)
This is the current way I am getting the downloads folder:
FileInfo file = new FileInfo(Path.Combine(Environment.ExpandEnvironmentVariables(#"%USERPROFILE%\Downloads"), data.Filename + "." + data.FileType));
However I have also tried the solution that Hans Passant has answered to a similar question here. Both solutions worjk fine while debugging locally however as soon as I publish them, this one produces the exception:
Value cannot be null. Parameter name: path1
Which I presume is thrown at this point here when I try and save the file to the user's download folder.
using (var package = new ExcelPackage(file))
{
var workSheet = package.Workbook.Worksheets.Add("ExportSheet");
workSheet.Cells.LoadFromCollection(exports, true);
package.Save();
}
I don't really know how I would be able to reproduce these exceptions seeing as locally using Visual Studio it all works fine.
Has anyone else came across this issue while trying to download a file?
UPDATE: When the application is running on IIS, it seems to be using that as the user profile instead of the actually user, so when it tries to navigate to the Downloads folder, it cannot find it. How can I force it to use the user's profile?
LoadUserProfile is already set to True.
Web applications have no knowledge of the end-user's computer's filesystem!
So using Environment.GetFolderPath or Environment.ExpandEnvironmentVariables in server side code will only reveal the server-side user (i.e. the Windows Service Identity)'s profile directories which is completely separate and distinct from your web-application's actual browser-based users OS user profile.
As a simple thought-experiment: consider a user running a weird alien web-browser on an even more alien operating system (say, iBrowse for the Amiga!) - the concept of a Windows-shell "Downloads" directory just doesn't exist, and yet here they are, browsing your website. What do you expect your code would do in this situation?
To "download" a file to a user, your server-side web-application should serve the raw bytes of the generated file (e.g. using HttpResponse.TransmitFile) with the Content-Disposition: header to provide a hint to the user's browser that they should save the file rather than try to open it in the browser.
I have an internal ASP.NET MVC site that needs to read an Excel file. The file is on a different server from the one that ASP.NET MVC is running on and in order to prevent access problems I'm trying to copy it to the ASP.NET MVC server.
It works OK on my dev machine but when it is deployed to the server it can't see the path.
This is the chopped down code from the model (C#):
string fPath = HttpContext.Current.Server.MapPath(#"/virtualdir");
string fName = fPath + "test.xlsm";
if (System.IO.File.Exists(fName))
{
// Copy the file and do what's necessary
}
else
{
if (!Directory.Exists(fPath))
throw new Exception($"Directory not found: {fPath} ");
else
throw new Exception($"File not found: {fName } ");
}
The error I'm getting is
Directory not found:
followed by the path.
The path in the error is correct - I've copied and pasted it into explorer and it resolves OK.
I've tried using the full UNC path, a mapped network drive and a virtual directory (as in the code above). Where required these were given network admin rights (to test only!) but still nothing has worked.
The internal website is using pass through authentication but I've used specific credentials with full admin rights for the virtual directory, and the virtual dir in IIS expands OK to the required folder.
I've also tried giving the application pool (which runs in Integrated mode) full network admin rights.
I'm kind of hoping I've just overlooked something simple and this isn't a 'security feature'.
I found this question copy files between servers asp.net mvc but the answer was to use FTP and I don't want to go down that route if I can avoid it.
Any assistance will be much appreciated.
First, To be on the safe side that your directory is building correctly, I would use the Path.Combine.
string fName = Path.Combine(fPath, "test.xlsm")
Second, I would check the following post and try some things there as it seems to be a similar issue.
Directory.Exists not working for a network path
If you are still not able to see the directory, there is a good chance the user does not have access to that network path. Likely what happened is the app pool running your application has access to the directory on the server. The production box likely doesn't have that same access. You would have to get with the network engineer to get that resolved.
Alternatively, you could write a Powershell script to run as a user who has access to both the production and the development server to copy the file over to the production server if that is your ultimate goal and your server administrators could schedule it for you if that is allowed in your environment.
I need to upload files from my asp.net (C#) page residing in the web server to a remote server.
I managed to upload files to remote server from localhost using this code:
string serverPath = "\\\\xx.xxx.xx.xx\\Folder\\" + FileUpload1.FileName;
FileUpload1.PostedFile.SaveAs(serverPath);
But after I published this code to my web server, it stopped working with the error "The network path was not found."
I have looked at a few solutions which suggest using UNC network share and implementing impersonation.
I couldn't figure out how to apply these solutions.
Can someone please give an example, or suggest a simpler solution.
Thanks!!
In FileUpload1.PostedFile.SaveAs(path), path is physical path of file, No Url. You must check:
is Physical folder Exsist?
is You have access to folder?
if answer of both question is true check this code:
string serverPath = #"\\xxx.xxx.xxx.xxx\Folder\";
if (!System.IO.Directory.Exists(serverPath))
System.IO.Directory.CreateDirectory(serverPath);
FileUpload1.PostedFile.SaveAs(serverPath + FileUpload1.FileName);
The account your application runs under must have write permissions to the folder you are trying to upload the file to: \\xx.xxx.xx.xx\Folder\. So you will have to configure the application pool in IIS to run under an account that will have sufficient permissions. Go to the application pool properties in the IIS management console where you will be able to specify an account to be used to run the application. By default it uses a built-in account which won't have any access to shared resources. Take a look at the following article which explains how to do so.
You need a virtual directory on your webserver to upload to. In code you'll have to use Server.Mappath("virtual path") function to get its server path and then save to it.
I have an upload function in my system that stores the files on the d drive e.g D:\KBFiles. Now i need to offer these files as links through internet explorer. Obviously i cant just offer a path e.g D:\KBFiles\test.pdf. Whats the best way to handle this scenario
Write "proxy" file with such code and call it DownloadFile.aspx:
string fileName = Request.QueryString["file"];
string filePath = Path.Combime("D:\\KBFile", fileName);
Response.WriteFile(filePath);
Then have such link:
test.pdf
This allows you to check the user permissions if you're using Login system and also you can check the requested file against some white list to prevent hacking attempts.
You need to create a Virtual Folder for that windows folder inside your WebApplication. As soon as IIS has mapped the virtual folder, it would be possible to use direct links, which would have your WebApplication as a root.
Am getting error when you are going to upload the file on specified folder in the server. Here I am going to upload P6100083.jpg in storeimg folder. When I am going to upload I am getting the following error:
Access to the path 'C:\inetpub\vhosts\bookmygroups.com\httpdocs\storeimg\P6100083.jpg' is denied.
Can anyone help me... How to use permisiion and were to use...
My code is while uploading image
if (FileUpload1.HasFile)
{
float fileSize = FileUpload1.PostedFile.ContentLength;
float floatConverttoKB = fileSize / 1024;
float floatConverttoMB = floatConverttoKB / 1024;
string DirName = "storeimg";
string savepath = Server.MapPath(DirName + "/");
DirectoryInfo dir = new DirectoryInfo(savepath);
// string savepath = "C:\\Documents and Settings\\ssis3\\My Documents\\Visual Studio 2005\\WebSites\\finalbookgroups\\" + DirName + "\\";
if (fileSize < 4194304)
{
string filename = Server.HtmlEncode(FileUpload1.FileName);
string extension = System.IO.Path.GetExtension(filename).ToUpper();
if (extension.Equals(".jpg") || extension.Equals(".JPG") || extension.Equals(".JPEG") || extension.Equals(".GIF"))
{
savepath += filename;
FileUpload1.SaveAs(savepath);
}
}
}
Thanks in advance
I have no success making my upload or any write operation on filesystem work on IIS7.
Still getting the error: Access to the path is denied.
My AppPool is running under Network Service. I have granted all kinds of accounts Full Control (Network Service, Network, IIS_IUSR, Administrator, Users, Everyone), restarted the webservice several times, studied all IIS7 settings, googled for two hours and nothing works.
IIS7 and WS2008 s-u-c-k-s. Sorry for the term. Anybody can help?
I just wanted to add: I noticed that in the upload's destination folder's Properties there's this checkbox named "Read-only (Only applies to files in folder)" and it's checked. It cannot be unchecked, comes back checked after unchecking and clicking the OK button. Is that IIS7 guarding it?
Editing this message to add the SOLUTION: My admin has turned off the silly UAC "the security confirmation feature" on our server, restarted the machine and it works now. No "write" access rights for "Network Service" or any other IIS-used account was needed. When accessing the file system in a ASP.NET web application using the integrated authentication and having the impersonation set to true in its web.confing, the file system seems to be accessed by the authentified end-user's account, not by the Network Service account which the AppPool is running under. (Many people tell you to set Network Service permissions, but that is not true.) So you need to set the "write" permissions for your end-users (usually domain users: "DOMAIN\domain users") on your particular folder.
Oh yea, and the "Read-only (Only applies to files in folder)" checkbox mentioned above does not seem to have any effect. However Microsoft says "some programs might have problems writing to such folder and you should use command line statement "attrib -r -s" to get rid of the Read-Only attribute" -- but it won't work. It will stay there checked-grayed. But don't worry about that. Microsoft becomes more and more silly every day.
Indead, it's a server issue.
You need to verify if the user underlying your application pool has write access to the directory.
If you use IIS7, you have a new feature that helps you give custom write to this user and dun need to change the user.
Look at this link:
http://www.adopenstatic.com/cs/blogs/ken/archive/2008/01/29/15759.aspx
Hope this helps.
This is a server issue. Make sure you have the necessary rights to write files.
Btw, since you call ToUpper() on extension there's no reason to test for ".jpg".
If you are using Plesk Panel, go to file manager of Plesk Panel. List files and folders inside "httpdocs". Each file and folder has a lock icon at the very right. Click that of "storeimg" folder to change permissions. Click advenced button. Give full permission to these:
Plesk IIS WP User (IWPD_214(your_login_name))
Plesk IIS WP User (IWPD_214(your_login_name))
And click OK.
First you check the permission is enable or not if not then go to that folder which folder has to be use for containing files then right click on folder then there will be display folder properties then click on security there will be display multiple number of user which user have to be permit then click allow that all permission will be activated.
First, make sure your code runs fine locally (I assume that something you've already done).
Then deploy to your TEST or UAT environment. If you're having issue there, then this is a configuration issue. Make sure the service account under which your website's app pool is running has access to the folder.
Please make use of C# method Path.Combine() to build up your path and avoid issues with leading or trailing / and \.
