Directory.CreateDirectory

This is really weird, but I have the following code:

private static readonly string mString = "tempUnzipDir" +
Path.DirectorySeparatorChar;

...

public static string ExtractToTempLocation(string aZip)
{
try
{
string tmp = Path.GetTempPath() + mString;
Directory.CreateDirectory(tmp);
// Extract the zip file
}
catch(Exception e)
{
}
}

The code above creates a temporary directory fine on my dev machine (Vista),
but will not create a temp directory on my server (server 2K3 R2) when I
move the code over the to server. I have some logging enabled that isn't
shown in the code above, and it is definately pointing to the correct
location of the temp directory to be created. Even more weird is that the
call to Directory.CreateDirectory(tmp); does not throw any type of exception
on the server. It just keeps executing as if it worked correctly. Does
anybody have any ideas why this isn't working?

Thanks.

Even more weird, if I change the code to this:
private static readonly string mString = "tempUnzipDir" +
Path.DirectorySeparatorChar + "anotherDir" + Path.DirectorySeparatorChar;

...

public static string ExtractToTempLocation(string aZip)
{
try
{
string tmp = Path.GetTempPath() + mString;
Directory.CreateDirectory(tmp);
// Extract the zip file
}
catch(Exception e)
{
}
}

I see the directory "tempUnzipDir" get created under the administrator's
temporary directory. However, the directory [administrator's temp
path]\tempUnzipDir\anotherDir does not get created. WTH??!!!

What type of application are you doing? When you say move code to "server",
does that mean a ASP.NET application, a Windows service application or a
desktop application? Without knowing which user account is used to run your
app, it is hard to tell what is wrong. But it ceratinly sounds like you have
permission problem. As for the code not throwing exception, if the code you
show is the real code, then of course the code does throw exception and is
caught in catch(){} block. However, since you did nothng in the "catch..."
block, the code continues. That is, if you use try...catch... and do nothing
when exception ia caught, that is equal to ignorig the exception and the
code would continue counting on your luck to finish.

I found the problem. It was a sync issue. This was a plug-in for a Windows
service. Another plug-in was deleting temp directories.

Sorry to bug everyone.

Try using System.IO.Path.Combine() method instead of string concat.
