如何在Windows中从C＃程序更改文件权限？

Question

我做了一个C＃windows应用程序，将搜索在C驱动器中文件夹 用户在文本框中输入，搜索将在用户按下按钮后开始。 的问题是，我得到一个异常告诉我：

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

我如何能发现在C盘的任何文件夹/文件（或任何其他驱动器），我没有访问和更改它的权限通过我的C＃程序来访问授予的或某事，以便我可以继续我的搜索？

在Linux中有输入chmod，但我不知道有关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资源管理器运行该程序 '作为管理员' 。
