c# 創建壓縮包並下載文件

public class IndexController: ICSharpCode.SharpZipLib.Core.INameTransform
{

#region INameTransform 成員

public string TransformDirectory(string name)
{
return null;
}

public string TransformFile(string name)
{
return Path.GetFileName(name);
}

#endregion
}

/// <summary>
/// 壓縮打包文件
/// </summary>
public ActionResult ZipFileByCode()
{
MemoryStream ms = new MemoryStream();
byte[] buffer = null;

using (ZipFile file = ZipFile.Create(ms))
{
file.BeginUpdate();
file.NameTransform = new IndexController();//通過這個名稱格式化器，可以將里面的文件名進行一些處理。默認情況下，會自動根據文件的路徑在zip中創建有關的文件夾。

file.Add(Server.MapPath("/Content/images/img01.jpg"));
file.Add(Server.MapPath("/Content/images/img02.jpg"));
file.CommitUpdate();

buffer = new byte[ms.Length];
ms.Position = 0;
ms.Read(buffer, 0, buffer.Length);
}
Response.AddHeader("content-disposition", "attachment;filename=test.zip");
Response.BinaryWrite(buffer);
Response.Flush();
Response.End();

return new EmptyResult();
}

}
