C＃-如何删除临时Internet文件

Question

我想完全清除Internet临时文件夹。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，因此它必须是动态的。

Answer 1

使用此路径：Environment.SpecialFolder.InternetCache

Environment.SpecialFolder.InternetCache

Answer 2

您可能还需要终止Internet Explore进程并更改目录属性，并且不要以为这对Index.dat文件有效，因为MS会不断更改规则。

单击我的名字以获得还将删除Firefox文件和Flash共享对象的代码

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
}

使用此功能Environment.GetFolderPath()获取路径。遍历它们时，删除该目录中包含的所有文件。

Answer 4

您可以做这样的事情。

Environment.SpecialFolder

Answer 5

我知道您可能不知道如何开始，但是StackOverflow并非旨在成为您可以打开并请求代码的地方。

无论如何，使您入门的真正基本代码是：

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
   }
}

当然，您必须考虑访问权限，锁定文件，子文件夹等。

我建议您从此开始，然后在实际有一些工作代码时再提出其他问题。
