运用CodeSmith代码生引擎生成XML报表文件。

运用CodeSmith代码生引擎生成XML报表文件。 前段时间做WEB项目时接到一个任务，报表都导出EXCEL。 不能用第三方的报表工具，那只能操作EXCEL Library来解决了。 第一种：在服务端调用COM写EXCEL发关到客户端； 这样不太可行因为系统的用户数量也很多,C#操作Excel(COM)效率不高，还很消耗服务器资源。 第二种:就是通过JSCRIPT来操作ActiveX,原理和第一种一样；只是操作数据操作放到客户端进行。 这两种方法操作和维护都很烦琐，而且效率也不高。 正在烦恼的时间突然想到了Excel到底能不能打开XML呢？ 试了一下发现是可以，然后在Excel画了一些表格另存为XML； 打开后看了一下，笑了我可以通过动态生成XML不就可以啦。 动态生成XML？就那些标记的组合就够烦，那会有直接操作COM来得方便直接？ 这里就要提一个工具了CodeSmith，它是一个基于模板的代码生成， 模板的语法和ASP差不多，如果写过ASP一看就知道他的原理。 这个工具在这里就不多介绍，有兴趣的朋友可以去了解一下。(当然还有其他代码生成工具，原理一样) 注意：Excel必须是XP或更高版本       HFSoft.Exports都是我自己封装的类

天啊这么复杂的XML自己如何写啊？我们不要忘了Excel，完全可以用Excel做模板导出XML的。 模板里的HFSoft.Exports.DataManager是我自己写的一个数据管理类，用于数据获取和分组的。 模板已经出来的，那我如何调用他来生成XML文件呢？ 以下是WEBFORM的一些调用代码。 private void Report(string Template,System.Data.DataSet ds)   {    HFSoft.Exports.ExportAdapter export = new HFSoft.Exports.ExportAdapter();    export.DataSource = ds;    string filename = Guid.NewGuid().ToString().Replace("-","") +".xml";    export.SaveFile =Request.PhysicalApplicationPath +@"Reports\"+ filename;    export.Template =Request.PhysicalApplicationPath +@"Reports\" + Template;    HFSoft.Exports.WebExcelReportControl excel = new HFSoft.Exports.WebExcelReportControl(export);    excel.HttpFile = "http://"+ Request.ServerVariables["SERVER_NAME"]+ Request.ApplicationPath +"/Reports/" + filename;    excel.Execute();    this.RegisterStartupScript(Guid.NewGuid().ToString(),excel.ReportJScript);   }   private void cmdCustomeList_Click(object sender, System.EventArgs e)   {    System.Data.SqlClient.SqlDataAdapter da = new System.Data.SqlClient.SqlDataAdapter("select *  from Customers",ConnectionString);    System.Data.DataSet myDS = new DataSet();    da.Fill(myDS);    Report("CustomerList.cst",myDS);   } 这样用XML导出EXCLE的事例就结束了。 其原理很简单就是数据结合XML生成最终XML文档给EXCEL打开，实现这样功能的做法也有很多。 对自己来说当然是选取自己感觉最方便的方法去实现。 我为了方便选用了第三工具做最烦琐的事件：）
