How to delete Zip file after copying into another folder

Question

how to delete a zip file after copying into another folder...I am getting exception while deleting..It is saying that "The file is being used by another process".

string pathString1 = FullFilePath;
string sourceFileName = Path.GetFileName(pathString1);
string foldername = Path.GetDirectoryName(pathString1);
string pathString = Path.Combine(foldername, "Uploaded");
if (!System.IO.Directory.Exists(pathString))
{
    System.IO.Directory.CreateDirectory(pathString);
    string destFile = System.IO.Path.Combine(pathString, sourceFileName);
    File.Copy(pathString1, destFile);

    File.Delete(pathString1);
    File.Delete(FileName);
}

You need to close the stream you are using to read the file. Once we can see your code we can help. — Peter Smith, Jul 28 '16 at 09:34
Where does the curly bracket in your code go? There is just one lone one — MasterXD, Jul 28 '16 at 09:41
It may be that the file is open in an antivirus type of program. — Lasse V. Karlsen, Jul 28 '16 at 09:42
Actually when i am giving text files the file is deleting..but when i am giving the zip at delete getting exception — Pinky, Jul 28 '16 at 10:00
because you say it is a problem with a .zip and not a .txt, makes me think it is a virus checker that you may have to wait for — Cato, Jul 28 '16 at 11:16

If you decompress the zip-file, then do this in a using block or .Dispose() the object that is responsible for decompressing. What lib are you using?

To prevent the locking of files, the using statement will release the file when it's done with the operation:

using (FileStream stream = File.Open("path to file", FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
    ...
}

Then again, if you're deleting the file right after you copy it, then why not just move it?

File.Move(from, to);

since there is this theory that a virus checker goes into your .zip file, you could re-try waiting for it to finish with retries

string pathString1 = FullFilePath;
string sourceFileName = Path.GetFileName(pathString1);
string foldername = Path.GetDirectoryName(pathString1);
string pathString = Path.Combine(foldername, "Uploaded");
if (!System.IO.Directory.Exists(pathString))
{
    System.IO.Directory.CreateDirectory(pathString);
    string destFile = System.IO.Path.Combine(pathString, sourceFileName);
    File.Copy(pathString1, destFile);

    int itries = 0;
    int maxtries = 30;    //suitable time of retrying
    while (itries++ < maxtries)
    {   
        try 
        {
            File.Delete(pathString1);
            itries = 999999;
        }
        catch (Exception ex)
        {
          if (itries > maxtries) throw ex;  
          Thread.Sleep(1000);
        }       

    }

    //File.Delete(FileName);
}
