You can try using the configuration file

<appSettings>

<add key="FileDirectory" value="C:\upload\"/>

</appSettings>

string directory = ConfigurationManager.AppSettings["FileDirectory"].Trim()

FileUpload1.SaveAs(directory + filename);

FileUpload1.SaveAs(+ filename);

You can try using the configuration file

<appSettings>

<add key="FileDirectory" value="C:\upload\"/>

</appSettings>

string directory = ConfigurationManager.AppSettings["FileDirectory"].Trim()

FileUpload1.SaveAs(directory + filename);

Do you have taken update panel for fileUpload?

Hi,

To resolve the error use this line of code
string filename = Path.GetFileName(FileUploadControl.FileName);
FileUploadControl.SaveAs(Server.MapPath("~/upload") + filename);

Instead of this
 filename =FileUpload1.PostedFile.FileName;
    FileUpload1.SaveAs(Server.MapPath("/upload/") + filename);

in mappath use upload as a folder to map

'c:\inetpub\wwwroot\upload\filterdes.xlsx'

in this your missing Website Name

FileUploadControl.SaveAs(Server.MapPath("~[WebsiteName]/upload") + filename);

Hi,

Request.ApplicationPath will return a virtual path string like "/WebApplication1". However, StreamReader require a physical path like "C:\inetpub\webapplication1\filterdes.xlsx". To convert a virtual path to physical path, we can use MapPath method:

MyFile =Server.MapPath(Request.ApplicationPath + "//filterdes.xlsx");

As i am checking there is no project in wwwroot on server according to path. Have you tried searching your project (configuration files included) for that path? It will be surely written somewhere, you just need to find it
