Your question does not makes much of a sense. Please elaborate on what you are trying to do and what is expected?

Firstly I dont see why you should be converting foreach to for.

If you still want to do it get the count of all files into a variable
and then run a for loop -

for(int i=0;i++,i<count)
{
      fi.CopyTo(Path.Combine(dest_d.ToString(), source_s.GetFiles()[i].Name), true);
}

where count is the list of your files.

I'm not absolutely sure if source_s.GetFiles()[i].Name this work as I dont know what source_s.GetFiles() is returning....

in foreach loop i have given reference to "fi" as fileinfo(FileInfo fi in source_s.GetFiles()) but in for loop how can i give reference to fi

Try source_s.GetFiles()[i].FileInfo.Name. You should be able to access the FileInfo inside GetFiles().

To avoid repeated calls to GetFiles(), which could slow your application down considerably, get the files once before starting the for loop.

FileInfo[] foundFiles = source_s.GetFiles();
for (int i = 0; i < foundFiles.Length; i++)
{
  foundFiles[i].CopyTo(Path.Combine(dest_d.ToString(), foundFiles[i].Name), true);
}

or even

C#

FileInfo[] foundFiles = source_s.GetFiles();
for (int i = 0; i < foundFiles.Length; i++)
{
  FileInfo fi = foundFiles[i];
  fi.CopyTo(Path.Combine(dest_d.ToString(), fi.Name), true);
}

which avoids another repeated data fetch.
