How to get full path from savefiledialog and use in "startInfo.Arguments"?

Question

In my case the SaveFileDialog will not write any file, but I want to use to specify the path for a command line app which will create the logfile on the same location as "saved" in the sf dialog.

SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "*.txt";
string sfdname = saveFileDialog1.FileName;
if (sfd.ShowDialog() == DialogResult.OK)
{
  Path.GetFileName(sfd.FileName);
}

startInfo.Arguments = "--log=" + Path.GetFileName(sfd.FileName);

Answer 1

You can use

Path.GetFullPath(sfd.FileName);

Instead of

Path.GetFileName(sfd.FileName);

Complete version...

SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "*.txt";
string sfdname = saveFileDialog1.FileName;
if (sfd.ShowDialog() == DialogResult.OK)
{
  Path.GetFullPath(sfd.FileName);
}

startInfo.Arguments = "--log=" + Path.GetFullPath(sfd.FileName);

OpenFileDialog openFileDialog1 = new OpenFileDialog();
                openFileDialog1.Filter = "Image files | *.jpg";
                if (openFileDialog1.ShowDialog() == DialogResult.OK)
                {
                 employee_dp.Image = Image.FromFile(openFileDialog1.FileName);
                 string path = System.IO.Path.GetDirectoryName(openFileDialog1.FileName);
                 string onlyFileName = System.IO.Path.GetFileName(openFileDialog1.FileName);
                 filepath = Path.GetFullPath(path).Replace(@"\", @"\\");
                 filepath = filepath + "\\\\" + onlyFileName;
                 MessageBox.Show(filepath);
