在小型.NET程序中管理临时文件

My question is about handling temporary files in a small .NET program. This program/utility just does the following with two URLs:

我的问题是在一个小的.NET程序中处理临时文件。此程序/实用程序只使用两个URL执行以下操作：

Download each URL to a string (WebClient.DownloadString).
Save each string to a temporary file.
Call WinMerge (Process.Start) to diff the two files (in read-only mode for both files).

I currently have the Simplest Thing That Could Possibly Work:

我目前有可能工作的最简单的事情：

save URL1 to windows/temp/leftFileToDiff.txt
save URL2 to windows/temp/rightFileToDiff.txt.

This works great - as WinMerge only needs to run in Read Only mode the files can be overwritten by running my program multiple times and nothing bad happens.

这很好用 - 因为WinMerge只需要在只读模式下运行，所以可以通过多次运行我的程序来覆盖文件，并且没有任何不好的事情发生。

However, I would now like to change the temporary file names to something meaningful (related to the URL) so that I can see which is which in the WinMerge view. I also want to clean these files up when they are no longer needed. What are my options for this?

但是，我现在想将临时文件名更改为有意义的（与URL相关），以便我可以看到WinMerge视图中的哪个。我还想在不再需要时清理这些文件。我有什么选择？

My next simplest idea is to have a specified folder where these are stored and just to zap this every time my program exits. Is there a better/more elegant/standard way?

我的下一个最简单的想法是拥有一个存储这些文件夹的指定文件夹，并且每次我的程序退出时都要删除它。有更好/更优雅/标准的方式吗？

Thanks.

谢谢。

Create a Guid-based folder under the user's temp area and use that?

在用户的临时区域下创建一个基于Guid的文件夹并使用它？

        string path = Path.Combine(Path.GetTempPath(),
              Guid.NewGuid().ToString("n"));
        Directory.CreateDirectory(path);
        try
        {
            // work inside path
        }
        finally
        {
            try { Directory.Delete(path, true); }
            catch (Exception ex) {Trace.WriteLine(ex);}
        }
