如何通过AC＃程序在Windows中更改文件权限？

Question

我制作了一个C＃Windows App程序，该程序将在C驱动器中搜索用户在文本框中输入的文件夹，然后在用户按下按钮后开始搜索。 问题是我收到一个异常消息：

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

如何在C驱动器（或其他任何驱动器）中发现我没有访问权限的任何文件夹/文件，并通过C＃程序更改其访问权限以授予权限或其他权限，以便我可以继续搜索？

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”运行程序。
