asp.net 用后台代码实现打印服务器的word文档
功能说明：
用户在网页上直接点击网页上的一个打印按钮，服务器就直接打印相对应的word文档出来。。
兄弟姐妹们，有搞过的快帮忙一下。。先谢谢！
[解决办法]
服务器安装Word
以Com组件方式调用Word
具体实现可以找找网上的调用Excel或者Word的代码
要是自己试的话，先在引用里面添加Com引用，把Word添加进去，然后再实例化Word，打开文件，打印，退出。
[解决办法]
在网上找找有没有第三方的打印控件?

提取DOC文件内容
[解决办法]
///public static void Main()
///{
/// OfficeFileReader.OfficeFileReader objOFR = new OfficeFileReader.OfficeFileReader()
/// string output="";
/// objOFR.GetText("C:\\MyWordFile.Doc", ref output);
/// Console.WriteLine(output);
///}
[解决办法]
//1.定义文档类型、字符编码
Response.Clear();
Response.Buffer = true;
Response.Charset = "utf-8";
//下面这行很重要， attachment 参数表示作为附件下载，您可以改成 online在线打开
//filename=FileFlow.doc 指定输出文件的名称，注意其扩展名和指定文件类型相符，可以为：.doc || .xls || .txt ||.htm
Response.AppendHeader("Content-Disposition", "online;filename=Paper.doc");
Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
//Response.ContentType指定文件类型 可以为application/ms-excel || application/ms-word || application/ms-txt || //application/ms-html || 或其他浏览器可直接支持文档
Response.ContentType = "application/ms-word";
this.EnableViewState = false;
//2.定义一个输入流
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
//3.将目标数据绑定到输入流输出
this.panel.RenderControl(oHtmlTextWriter);
//this 表示输出本页，你也可以绑定datagrid,或其他支持obj.RenderControl()属性的控件
Response.Write(oStringWriter.ToString());
Response.End();
//toFiles(1);
