清除Cookies

        /// <summary>
        /// 清除Cookies
        /// </summary>
        void ClearCookies()
        {
            const int cookies = 33;
            Shell32.Folder objFolder;// 需要引用 Shell32.dll
            Shell32.FolderItems objFolderItems;
            Shell32.ShellClass objShell;

            objShell = new Shell32.ShellClass();
            objFolder = objShell.NameSpace(cookies);
            objFolderItems = objFolder.Items();
            foreach (Shell32.FolderItem objFolderItem in objFolderItems)
            {
                if (!"index.dat".Equals(objFolderItem.Name.ToLower()))
                {
                    System.IO.File.Delete(objFolderItem.Path.ToString());
                }
            }
        }

代码很简单,没什么好说的.
就是把Cookies文件夹里面的内容都删除了,因为文件"index.dat"是不能删除的,所以排除在外.

另:

Shell32.ShellClass.NameSpace(object  vDir)可以获取很多系统目录,参数的枚举值如下:
