C#-如何删除临时internet文件

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，不要以为这对Index.dat文件有效，因为MS不断更改规则。

点击我的名字，代码也删除Firefox文件和闪存共享对象

使用带有Environment.SpecialFolder枚举的函数Environment.GetFolderPath()获取路径。删除该目录中包含的所有文件，同时对其进行迭代。

您可以这样做。

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
   }
}

我知道你可能不知道如何开始，但StackOverflow并不是一个你可以直接出现并请求代码的地方。

在任何情况下，让你开始的一个真正的基本代码是：

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

当然，你必须考虑访问权限、锁定的文件、子文件夹等。

我建议你从这个开始，然后当你真的有一些工作代码时再提出进一步的问题。
