DirectoryNotFoundException when running from PCs other than Server in C#

Question

I have developed a console application which zips up files within a directory with password to a destination folder. I am zipping files within a directory to a destination folder with password.

This is the code. In my local PC its working fine. I have created setup for this application and installed on my PC as well as other PCs too. In my PC its working fine. but on other PCs its giving exception. Can you please tell me what could be the issue and how should I solve it? Is this permission related issue or some other issue.

        //zip.ExtractExistingFile= ExtractExistingFileAction.OverwriteSilently;
        // zip.ExtractAll(Environment.CurrentDirectory, .OverwriteSilently);
        //var result = zipFile.Any(entry => entry.FileName.EndsWith("input.txt"));

probably the client machine don´t have that directory. take a look at this — Marciano.Andrade, Jan 31 '14 at 15:19
You only seem to check if the directory exists when the '-d' argument is used. Shouldn't you always perform this check (i.e. take it outside of the argument loop)? — SpruceMoose, Jan 31 '14 at 15:20
these are the arguments -p nuna -s D:\Source -d D:\Destination\ — Brijraj, Jan 31 '14 at 15:25
if this issue is related to permission then how to solve it ? — vivek jain, Jan 31 '14 at 15:29
You should probably log out what the directory is (and what directory is created). Also, might be worth using 'Path.Combine()' in case the directories are not supplied with a trailing '\'. — SpruceMoose, Jan 31 '14 at 15:43
Creating strFullFilePath with `+` is a bad idea. Use `Path.Combine(...)` instead. TimeStamp is strange, why don't you write `DateTime TimeStamp = DateTime.Now;` ? — Xaruth, Jan 31 '14 at 15:46
I think you have different CurrentCulture. So ToShortDateString() return different string, and may be with a "/". — Xaruth, Jan 31 '14 at 15:55
I agree with @Xaruth. I was able to reproduce your problem and then fix with the change he suggests. — SpruceMoose, Jan 31 '14 at 15:59

I think this code is strange :

System.DateTime Timestamp = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second);
string strFileName = Timestamp.ToShortDateString();
strFullFilePath = args[i] + strFileName + ".zip";

First, you can write

DateTime Timestamp = DateTime.Now;

Then ToShortDateString depend on CurrentCulture. Force what you want (for exemple :)

String strFileName = Timestamp.ToString("yyyyMMdd");

Exception is from here, on my mind. With wrong Culture, you can have "/" in your format string.

Then, use Path.Combine instead of operator + (no error with a missing slash)

strFullFilePath = Path.Combine(args[i], strFileName + ".zip");

Edit For those who can't format DateTime, here my code (and that works) :

public static class Constantes
{
    public const String DateTimePattern = "yyyyMMddHHmmss";
}

public class SaveProcessViewModel : NotificationObject
{
[...]
    String zipFileName = System.Environment.MachineName + "-" + DateTime.Now.ToString(Constantes.DateTimePattern) + ".zip";
    String tempZipFile = Path.Combine(Path.GetTempPath(), zipFileName);

    zip.Save(tempZipFile);
[...]
}

Your format specified should be "yyyyMMdd" - MM is month, yours has mm = minutes. – Joe Jan 31 '14 at 16:10
I did it by memory. Never remember wich is upper or lower ^^ – Xaruth Jan 31 '14 at 16:11
Not working in my case. I have done changes as suggested by you. – vivek jain Jan 31 '14 at 16:30
Commented DateTime code and its working fine. it means it was issue related to culture. Now If I want that zip file should be created with the date. how to set it – vivek jain Jan 31 '14 at 16:44
See my edit. Use `ToString("yyyyMMdd")` or something like that to format your DateTime. – Xaruth Jan 31 '14 at 17:25
