C＃ - 如何刪除臨時Internet文件

Question

我想完全清除臨時Internet文件夾。該文件夾的位置（例如C:\Users\Username\AppData\Local\Microsoft\Windows\Temporary Internet Files）取決於Windows的版本，因此它必須是動態的。

Answer 1

使用此路徑：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 
} 

Answer 2

使用此功能Environment.GetFolderPath()與Environment.SpecialFolder枚舉獲取的路徑。在遍歷它們時刪除該目錄中包含的所有文件。

Answer 3

First hist in google, seams to be nice :) - 你也可能需要殺死IEXPLORE.EXE

Answer 4

你可以做這樣的事情。

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 
    } 
} 

Answer 5

我知道你可能不知道如何開始，但是StackOverflow並不打算成爲一個你可以打開和請求代碼的地方。

在任何情況下，讓你開始的代碼真正的基本位將是這樣的：

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

當然你必須要考慮的東西像訪問權限，鎖定的文件，子文件夾等

我建議你先從這個開始，然後在你實際上有一些工作代碼時再回來提問。

Answer 6

您可能還需要終止Internet Explore並更改目錄屬性，並且不要以爲這會對Index.dat文件起作用，因爲MS會不斷更改規則。
