批量保存 htm

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();            
        }

        class MemoryDataSource : IStaticDataSource
        {
            #region Constructors
            /// <summary>  
            /// Initialise a new instance. 
            /// </summary>  
            /// <param name="data">The data to provide.</param>
            public MemoryDataSource(byte[] data)
            {
                data_ = data;
            }
            #endregion

            #region IDataSource Members
            /// <summary>
            /// Get a Stream for this <see cref="IStaticDataSource"/>   
            /// </summary>  
            /// <returns>Returns a <see cref="Stream"/></returns>
            public Stream GetSource()
            {
                return new MemoryStream(data_);
            }
            #endregion
            #region Instance Fields
            readonly byte[] data_;
            #endregion
        }
