Question

check write permission on a folder (C#)

Asked by: mte01

Hi,
is there a way (or do i need) to check the write access to a folder using C# before using it?

like my application saves images in a user defined folder, do i have to check if logged in user have write access to this folder before allowing him to set it as destination folder?
does the following code does that?

if (captureImagefolderBrowserDialog.ShowDialog() == DialogResult.OK)
            {
                //Need to test if we have write access to the selected folder.
                string filePath = captureImagefolderBrowserDialog.SelectedPath ;
                System.IO.DirectoryInfo directoryInfo = new System.IO.DirectoryInfo(filePath);

                FileIOPermission f = new FileIOPermission(FileIOPermissionAccess.Write, filePath);
                f.AllLocalFiles = FileIOPermissionAccess.Write;
                try
                {
                    f.Demand();
                }  
                catch (Exception s)
                {
                    Console.WriteLine(s.Message);
                }
                this.txtCaptureImagesLocation.Text = filePath;
            }
