Problem with RegEx.Replace and trying to change a filename
- by fraXis
Hello,
I am having a strange problem and I can't seem to figure it out.
My filename is something like this:
DER 1513016-3.020F.NCF.
I want to be able to change it to:
DER 1513016-3.020H.NCF
Sometimes the filename can be this as well:
DER 1513016-3.020F_NEW.NCF
which would change to:
DER 1513016-3.020H_NEW.NCF
This is my code to do this:
OpenFileDialog fDialog = new OpenFileDialog();
fDialog.Title = "Open";
fDialog.Filter =
"NCF files (*.ncf)|*.ncf|All files (*.*)|*.*";
fDialog.InitialDirectory = @"C:\Program Files\";
if (fDialog.ShowDialog() == DialogResult.OK)
{
string newfilename;
string fileext = Path.GetExtension(fDialog.FileName);
newfilename = Regex.Replace(fDialog.FileName, "F.NCF", "H.NCF");
newfilename = Regex.Replace(fDialog.FileName, "F_NEW.NCF", "H_NEW.NCF");
}
This is where things get wierd. The way the code works now, it will NOT change the filename to DER 1513016-3.020H.NCF
If I comment out this line of code:
//newfilename = Regex.Replace(fDialog.FileName, "F_NEW.NCF", "H_NEW.NCF");
it will work fine and the file will now become: DER 1513016-3.020H.NCF
However, if I uncomment that line of code, the filename will not change to DER 1513016-3.020H.NCF. It will stay as DER 1513016-3.020F.NCF.
Why is that line of code causing the routine to not change the filename?
Thanks,
