如何从 C# 程序更改 Windows 中的文件权限？

Question

我制作了一个 C# windows App 程序，它将在 C 驱动器中搜索文件夹 用户在文本框中输入，搜索将在用户按下按钮后开始。 问题是我收到一个异常告诉我：

Access To The Path 'C:\Documents and Settings' is Denied

如何在 C 驱动器（或任何其他驱动器）中发现我无权访问的任何文件夹/文件，并通过我的 C# 程序更改其权限以授予访问权限或其他内容，以便我可以继续我的搜索？

在 Linux 中有 chmod，但我不知道 windows .. 请帮助 :)

搜索代码：

string operationSucceeded = "Operation Completed Successfully";
Exception NoFilesFound = new Exception("No File(s) Found In Specified Directory");
List<string> foundFolders = new List<string>();

private void button5_Click(object sender, EventArgs e)
{
  try
  {
    Search_In_For("C:\\", WantedFile_Folder_TextBox.Text);
    if (foundFolders == null) throw NoFilesFound;
    for (int i = 0; i < foundFolders.Count; i++)
    SearchResultsTextBox.Text += (foundFolders[i] + "\n");
    MessageBox.Show(operationSucceeded);
  }
  catch (Exception ex)
  {
    MessageBox.Show(ex.Message);
  }
}

delegate void SearchDelegate(string searchDir, string wanted);

private void Search_In_For(string searchDir, string wanted)
{
  string[] foldersInThisDir = Directory.GetDirectories(searchDir);
  if (foldersInThisDir.Length == 0) return;
  for (int i = 0; i < foldersInThisDir.Length; i++)
    if (foldersInThisDir[i].Contains(wanted))
      foundFolders.Add(foldersInThisDir[i]);
  SearchDelegate sd = new SearchDelegate(Search_In_For);
  for (int i = 0; i < foldersInThisDir.Length; i++)
    sd(foldersInThisDir[i] , wanted);
}

尝试从 Windows 资源管理器“以管理员身份”运行您的程序。
