I am developing website using Visual Studio 2010. I am trying to save a file in a path. It works fine localhost.
But the same code is not working in IIS. It shows the following error
Exception Details: System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Inetpub\wwwroot\Vendor\cn.jpg'.
Could not find a part of the path 'C:\Users\shashank\Desktop\ab.csv'.
Here is the code:
protected void btnImportFile_Click(object sender, EventArgs e)
{ sArReportText = File.ReadAllText(txtFilePath.Text.Trim()); // Set the report Properties to insert Report information SetProperties();

You might also be experiencing what I am: that the directory name contains some unusual characters. In my case,
Could not find a part of the path 'C:\Web\metBoot\wild iis\DigiCert© Certificate Utility for Windows_files'.That copyright sign is the issue.
So using concepts drawn from Obtaining the short 8.3 filename from a long filename, I convert my paths to short form first, then use that to get my list of files.
StringBuilder sf = new StringBuilder(300);
int n = GetShortPathName(sourceFolder, sf, 300);
if (0 == n)
{ tk.write(Marshal.GetLastWin32Error().ToString()); continue;
}...
IEnumerable<string> fileGroup = Directory.EnumerateFiles(sf.ToString(), ext);Consider how you're launching VS too. Counter-intuitively I run into this problem only when I'm running VS in Administrator mode. Possibly a group policies thing.
1This may be because, you are not having the specified file in web server, or you may be used an incorrect path. Specify the exact folder and filename as how it is stored in the web server. use HttpContext.Current.Request.ApplicationPath or Server.MapPath to specify the correct location where your desired file lies. And also make sure that you have given read and write permissions for this specific file and its folder.
You need to have permissions set in iis to allow files to be saved in the folder. Basically your uploaded files should be saved inside a separate folder present inside your root directory.
In order to access, create and delete files on the server, must have rights. Like in my project I am using Impersonator class to access various files and folder from the server. Otherwise it will throw an exception.
You could use code impersonation:
regardless, whomever you use as the impersonation must be able to read/write to the location that is being saved to. We use this method in applications for delete/create folders across network. Even if App_Data is best practice, it may be a business requirement to access the documents outside of that folder.
You can also set impersonation on IIS.
I also notice that your function is called btnImportFile. You may want to look into FileUpload control if you are uploading a file, which allows you to get the byte array of the file and save as needed. . You might still need to use Server.MapPath or HttpContext.Current.Request.ApplicationPath depending on your needs.
It's usually best practice to use the App_Data folder to save files to.
