公司项目，需要对一个列表做批量保存到Doc的功能。
后来通过架构人员协助，采用MemoryStream二进制流的方式保存为htm文档。
然后通过第3方的dll，ICSharpCode.SharpZipLib打包成zip文件。
抛弃doc的原因是流的形式保存为doc，office会解析为htm，但是Word样式很难维护，出现表格变粗的情况。
本地解压缩，从而实现批量保存的功能。
代码如下，
public void CreateZip()
{
List<MemoryStream> memList = new List<MemoryStream>();
for (int i = 0; i < 200; i++)
{
string a = @"<html>
<head>
<meta http-equiv='Content-Type' content='text/html; charset=utf8'>
<title>Ctrip.com Internet & Intranet - ViewEmail</title>
</head>
<body>
<h1>test</h1>
</body>
</html>";
byte[] b = Encoding.GetEncoding("gb2312").GetBytes(a);
MemoryStream mstream = new MemoryStream();
mstream.Write(b, 0, b.Length);
memList.Add(mstream);
}
MemoryStream ms = new MemoryStream();
using (ZipFile zipF = ZipFile.Create(ms))
{
zipF.BeginUpdate();
for (int i = 0; i < memList.Count; i++)
{
zipF.Add(new MemoryDataSource(memList[i].GetBuffer()), "a" + i.ToString() + ".htm");
}
zipF.CommitUpdate();
}
//将MemoryStream转换，否则发送时候可能出错
byte[] byteBuffer = ms.ToArray();
ms.Flush();
ms.Close();
Response.Clear();
Response.ContentType = "Application/zip";
Response.AppendHeader("content-disposition", "attachment; filename=" + System.Web.HttpUtility.UrlEncode("test" + DateTime.Now.ToString("yyyyMMdd") + ".zip", System.Text.Encoding.UTF8));
Response.BinaryWrite(byteBuffer);
Response.End();
}
protected void Button1_Click(object sender, EventArgs e)
{
CreateZip();
}

{
