.NET/C# – CreateTemporaryRandomDirectory (via: Stack Overflow)
Posted by jpluimers on 2013/06/13
A while ago I needed unique temporary directories. This appears not to be standard functionality in the .NET System.IO.Path or System.IO.Directory class.
Josh Kelley asked a question about it before, and I adapted the example by Scott-Dorman based on GetTempPath and GetRandomFileName and comments by Chris into a more robust CreateTemporaryRandomDirectory one that works in .NET 2.0 and higher:
[sourcecode language=”csharp”]
using System.IO;
namespace BeSharp.IO
{
public class DirectoryHelper
{
public static string GetTemporaryDirectory()
{
do
{
try
{
string tempPath = Path.GetTempPath();
string randomFileName = Path.GetRandomFileName();
string tempDirectory = Path.Combine(tempPath, randomFileName);
Directory.CreateDirectory(tempDirectory);
return tempDirectory;
}
catch (IOException /* ex */)
{
// continue
}
} while (true);
}
}
}
[/sourcecode]
You can call it like this:
[sourcecode language=”csharp”]
using System;
using BeSharp.IO;
namespace CreateTemporaryRandomDirectory
{
class Program
{
static void Main(string[] args)
{
string temporaryDirectory = DirectoryHelper.GetTemporaryDirectory();
Console.WriteLine("Temporary directory {0}", temporaryDirectory);
}
}
}
[/sourcecode]

You know, the idea of infinite retries in face of exceptional conditions just makes me shudder :)

It’s not the most beautiful code I ever wrote (:
If you have an idea for a cleaner way, please let me know!
