ZipClass zc = new ZipClass();

// DirectoryInfo zipPath = new DirectoryInfo(copyPath);

// zipPath.Delete(); //删除文件夹

//删除文件夹

Response.AddHeader("Content-Disposition", "attachment;filename=" + Server.UrlEncode("xlt.zip"));//解决文件名中文乱码

string filename = Server.MapPath("Zip/xlt.zip");

Response.TransmitFile(filename);

Response.End(); //解决txt中出现乱码

fi = new FileInfo(Server.MapPath("Zip/xlt.zip"));

}

//删除文件夹

private void DeleteFolder(string folder){

{

foreach (string filepath in Directory.GetFileSystemEntries(folder))

{

//循环删除文件

}

//递归删除子文件夹

else {

}

}

}

else {

throw new Exception("文件夹 " + folder + "不存在！");

}
