C＃访问路径被拒绝

嘿家伙，所以我在一个程序上工作，它删除了某些目录文件，主要是临时文件，除了我得到一个错误，甚至知道我添加了一个catch块。 System.UnauthorizedAccessException。在捕捉IOException异常我到达那里的错误：C＃访问路径被拒绝

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); 

    } 
}

而下面这个人是我如何调用该方法：

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

此外，DeleteInternetFiles方法中的参数称为字符串internetDirectory，某些原因无法发布它。 – DialUp

第二个catch块只捕获原始try中代码中的UnauthorizedAccessException，而不是从第一个catch块中获取。 – BurningLights
