C＃訪問路徑被拒絕

嘿傢伙，所以我在一個程序上工作，它刪除了某些目錄文件，主要是臨時文件，除了我得到一個錯誤，甚至知道我添加了一個catch塊。 System.UnauthorizedAccessException。在捕捉IOException異常我到達那裏的錯誤：C＃訪問路徑被拒絕

private void DeleteInternetFiles(string internetDirectory) 
{ 
    DirectoryInfo internetTempStorage = new DirectoryInfo(internetDirectory); 
    try 
    { 
     //this will delete files 
     foreach (FileInfo getNetFileInfo in internetTempStorage.GetFiles()) 
     { 
      getNetFileInfo.Delete(); 
     } 

     //this will loop through and delete folders 
     foreach (DirectoryInfo tempDirectoryInformation in internetTempStorage.GetDirectories()) 
     {   
      tempDirectoryInformation.Delete(); 
     } 
    } 

    //catch io exception and try delete file again 
    catch (IOException) 
    { 
     //delete file in this directory 
     File.Delete(internetDirectory); 

     //delete folders in this directory 
     Directory.Delete(internetDirectory); 
    } 

    //catch access exception and delete file again 
    catch (UnauthorizedAccessException) 
    { 
     //delete file in this directory 
     File.Delete(internetDirectory); 

     //delete folders in this directory 
     Directory.Delete(internetDirectory); 

    } 
}

而下面這個人是我如何調用該方法：

if (checkBox1.Checked) 
{ 
    DeleteInternetFiles(@"C:\Users\" + Environment.UserName + @" \AppData\Local\Microsoft\Windows\Temporary Internet Files"); 
}

此外，DeleteInternetFiles方法中的參數稱爲字符串internetDirectory，某些原因無法發佈它。 – DialUp

第二個catch塊只捕獲原始try中代碼中的UnauthorizedAccessException，而不是從第一個catch塊中獲取。 – BurningLights
