I have two files LS_PRSAHD_61417920_Cleaned.txt and LS_PRSAHD_67543245_Cleaned.txt. I want to rename the files as LS_PRSAHD_61417920.txt and LS_PRSAHD_67543245.txt.

I have tried this one . but not working.

C#

for (int i = 0; i < FilesHD.Length; i++)
            {

                FileInfo fi = new FileInfo(FilesHD[i]);
                sourcefilename = fi.Name;
                string cleanedfiles = Sourcefolder + sourcefilename;
                string originalfiles = sourcefilename.Substring(0, sourcefilename.Length - 12) + ".txt";
                if (File.Exists(cleanedfiles))
                {

                    File.Move(cleanedfiles, originalfiles);
                }

            }

Kindly give some info.

Not working is not informative at all. Please, be more specific. What kind of error do you have?

If the text to remove is always _Cleaned, you might want to search the last occurrence of that sting in the file name and then remove it. This might allows stronger validation.

assuming that you dont have any exception in line

C#

sourcefilename = fi.Name;

your file existence check returns false (possibly) here:

C#

if (File.Exists(cleanedfiles))

because of improper file path creation in line

C#

string cleanedfiles = Sourcefolder + sourcefilename;

use Path.Combine method to get a proper full path.

C#

cleanedfiles= Path.Combine(Sourcefolder, sourcefilename);

and to be sure, you can add 'else' part for the if(File.Exists)
