如何建立在asp.net

Question

zip文件，我需要創建該文件夾的壓縮文件，路徑爲：

D:\Nagaraj\New Project Read Document\TCBILPOS\TCBILPOS\TCBILPOS\FileBuild\HOST 

主機文件夾中有7 txt文件。

我想上面的文件夾中創建壓縮文件HOST.zip：提前

D:\Nagaraj\New Project Read Document\TCBILPOS\TCBILPOS\TCBILPOS\FileBuild 

感謝。

Answer 1

這可以很容易使用，現在用asp.net C＃來完成，

這裏是使用System.IO.Packaging程序庫的例子：

Answer 2

在我使用Ionic ZIP此我們自己的項目。

using (ZipFile zip = new ZipFile()) 
{ 
    // add this map file into the "images" directory in the zip archive 
    zip.AddFile("c:\\images\\personal\\7440-N49th.png", "images"); 
    // add the report into a different directory in the archive 
    zip.AddFile("c:\\Reports\\2008-Regional-Sales-Report.pdf", "files"); 
    zip.AddFile("ReadMe.txt"); 
    zip.Save("MyZipFile.zip"); 
}

最流行的第三方庫的（可能是因爲它是免費的）是SharpZipLib：http://www.icsharpcode.net/opensource/sharpziplib/

public class Ziper 
{ 
    public static string MapPathReverse(string fullServerPath) 
    { 
     return @"~\" + fullServerPath.Replace(HttpContext.Current.Request.PhysicalApplicationPath, String.Empty); 
    } 
    public static void Zip(HttpResponse Response, HttpServerUtility Server, string[] pathes) 
    { 
     Response.Clear(); 
     Response.BufferOutput = false; // false = stream immediately 
     System.Web.HttpContext c = System.Web.HttpContext.Current; 
     //String ReadmeText = String.Format("README.TXT\n\nHello!\n\n" + 
     //         "This is text for a readme."); 
     string archiveName = String.Format("archive-{0}.zip", 
              DateTime.Now.ToString("yyyy-MMM-dd-HHmmss")); 
     Response.ContentType = "application/zip"; 
     Response.AddHeader("content-disposition", "filename=" + archiveName); 

     var path = Server.MapPath(@"../Images/TempFile/TempFile" + DateTime.Now.Ticks); 
     if (Directory.Exists(path) == false) 
      Directory.CreateDirectory(path); 
     var pathzipfile = Server.MapPath(@"../Images/TempFile/zip_" + DateTime.Now.Ticks + ".zip"); 
     for (int i = 0; i < pathes.Length; i++) 
     { 
      if (File.Exists(pathes[i])) 
      { 
       string dst = Path.Combine(path, Path.GetFileName(pathes[i])); 
       File.Copy(pathes[i], dst); 
      } 

     } 
     if (File.Exists(pathzipfile)) 
      File.Delete(pathzipfile); 
     ZipFile.CreateFromDirectory(path, pathzipfile); 
     { 
      byte[] bytes = File.ReadAllBytes(pathzipfile); 
      Response.OutputStream.Write(bytes, 0, bytes.Length); 
     } 
     Response.Close(); 
     File.Delete(pathzipfile); 
     Directory.Delete(path, true); 
    } 
    public Ziper() 
    { 

    } 
}
