C# - 如何删除临时Internet文件

标签: c# windows .net-4.0 temporary-files

我想完全清除临时Internet文件夹。文件夹的位置(例如C:\Users\Username\AppData\Local\Microsoft\Windows\Temporary Internet Files)取决于Windows的版本,因此必须是动态的。

使用此路径:Environment.SpecialFolder.InternetCache

string path = Environment.GetFolderPath(Environment.SpecialFolder.InternetCache)
//for deleting files
System.IO.DirectoryInfo di = new DirectoryInfo(path);
foreach (FileInfo file in di.GetFiles())
{
    file.Delete(); 
}
foreach (DirectoryInfo dir in di.GetDirectories())
{
    dir.Delete(true); //delete subdirectories and files
}

您可能还需要终止进程Internet Explore并更改目录属性,不要认为这适用于Index.dat文件,因为MS不断更改规则。

获取使用此函数Environment.GetFolderPath()Environment.SpecialFolder枚举的路径。在迭代它们的同时删除该目录中包含的所有文件。

First hist in google, seams to be nice :) - 你也可能需要杀死iexplore.exe

答案 4 :(得分:-1)

你可以这样做。

using System.IO;

public static void Main()
{
 ClearFolder(new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.InternetCache))); // Execute ClearFolder() on the IE's cache folder
 }

 void ClearFolder(DirectoryInfo diPath)
 {
   foreach (FileInfo fiCurrFile in diPath.GetFiles())
   {
      fiCurrFile.Delete();
   }
   foreach (DirectoryInfo diSubFolder in diPath.GetDirectories())
   {
      ClearFolder(diSubFolder); // Call recursively for all subfolders
   }
}

答案 5 :(得分:-1)

我知道您可能不知道如何开始,但StackOverflow并不打算成为您可以调出并请求代码的地方。

在任何情况下,一个真正基本的代码就是这样:

List<string> someFiles = Directory.EnumerateFiles(Environment.GetFolderPath(System.Environment.SpecialFolder.InternetCache)).ToList();
foreach (var fileName in someFiles)
    File.Delete(fileName);

当然,您必须考虑访问权限,锁定文件,子文件夹等内容。

我建议你从这开始,然后在你真正有一些工作代码的时候再回答一些问题。
