C# - How to Delete temporary internet files

提问by MonsterMMORPG

I want to clear the temporary Internet files folder completely. The location of the folder, e.g., C:\Users\Username\AppData\Local\Microsoft\Windows\Temporary Internet Files, depends on the version of Windows, so it has to be dynamic.

我想彻底清除 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。

use this path: Environment.SpecialFolder.InternetCache

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
}

You may also need to kill the process Internet Explore and change the directory attributes and don't go thinking this will work for Index.dat files bacause MS keep changing the rules.

您可能还需要终止 Internet Explorer 进程并更改目录属性，不要认为这对 Index.dat 文件有效，因为 MS 不断更改规则。

Get the path from using this function Environment.GetFolderPath()with Environment.SpecialFolderenumeration. Delete all files contained in that directory while iterating over them.

Environment.GetFolderPath()通过Environment.SpecialFolder枚举使用此函数获取路径。在迭代它们时删除该目录中包含的所有文件。

You could do something like this.

你可以做这样的事情。

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
   }
}

I understand you may not know how to get started, but StackOverflow is not intended to be a place where you can just turn up and request code.

我知道您可能不知道如何开始，但是 StackOverflow 并不是一个您可以直接出现并请求代码的地方。

In any case, a real basic bit of code to get you started would be this:

无论如何，让您入门的真正基本代码如下：

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

Of course you have to consider things like access permissions, locked files, subfolders, etc.

当然，您必须考虑访问权限、锁定文件、子文件夹等内容。

I would suggest you start with this, then come back with further questions when you actually have some working code.

我建议你从这个开始，然后当你真正有一些工作代码时再回来回答更多的问题。
