如何从C#程序更改Windows中的文件权限

Question

我制作了一个C#窗口应用程序，该程序将在C驱动器中搜索文件夹如果用户在文本框中输入，则搜索将在用户按下按钮后开始。问题是，我收到了一个异常，告诉我：

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

我如何发现C驱动器（或任何其他驱动器）中我没有访问权限的任何文件夹/文件，并通过我的C#程序将其权限更改为授予访问权限或其他权限，以便继续搜索？

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资源管理器运行程序"作为管理员"。
