在 Vista 上，GetFolderPath (... CommonApplicationData)仍然返回“ C: 文档和设置”

据我所知，你应该使用 Environment.GetFolderPath方法，这样你就有了独立于操作系统的代码..。

WindowsXP 使用 C:\Documents and Settings\，WindowsVista 使用 C:\ProgramData和 C:\Users。

我在 Windows Vista 电脑上使用下面的代码，它返回的是 C:\Documents and Settings\目录，而不是 C:\ProgramData目录。有什么想法吗？

    string commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
try
{
File.CreateText(
Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) +
"\\mycompany\\uid");
log.Debug("Created file successfully");
}
catch (Exception ex)
{
log.Error("Unable to create the uid file: ", ex);
}

最佳答案

My installer copied a log.txt file which had been generated on an XP computer. I was looking at that log file thinking it was generated on Vista. Once I fixed my log4net configuration to be "Vista Compatible". Environment.GetFolderPath was returning the expected results. Therefore, I'm closing this post.

The following SpecialFolder path reference might be useful:
