说明:我要实现的就是将数据库中Group表的数据查找出来,替换打印模版中的内容,再将模版文件打印出来

1、准备好要打印的模版group_O_train.html

技术分享
 1 <div  class="pagetitle title">出国(境)培训人员汇总表</div>
 2     <div>项目编号:{项目编号}</div>
 3     <table class="pagedtable" style="width:25cm;font-size:9pt;border-collapse:collapse;" cellspacing=0 cellpadding=3px border=1 bordercolor=black>
 4     <thead style="text-align:center">
 5         <tr>
 6             <td style="width:0.6cm">序号</td>
 7             <td style="width:1.5cm">姓 名</td>
 8             <td style="width:0.8cm">性别</td>
 9             <td style="width:2.0cm">出 生<br />年月日</td>
10             <td style="width:1.5cm">出生地</td>
11             <td style="width:1.0cm">政治面貌</td>
12             <td style="width:4.5cm">工作单位</td>
13             <td style="width:2.7cm">职务或<br />职 称</td>
14             <td style="width:4cm">何年毕业于<br />何校、何专业</td>
15             <td style="width:2cm">目前从事的<br />实际工作</td>
16             <td style="width:1.0cm">备注</td>
17         </tr>
18     </thead>
19     <tbody>    
20     {人员名单}
21     </tbody>
22     </table>
23     <p class="alignright" style="width:25cm">出国(境)归口管理部门公章</p>

2、打印通用页面,其中<div id="pPrintContent" runat="server">是模版要替换的内容

 1 <%@ Page Language="C#" AutoEventWireup="true" CodeFile="DocumentPrint.aspx.cs" Inherits="Abroad_DocumentPrint" EnableViewState="false" %>

 3 <html xmlns="http://www.w3.org/1999/xhtml" >

20         </div>
21     </div>
22     <div id="pPrintContent" runat="server">
23     错误,没有内容!请检查调用参数是否正确.
24     </div>
25     </form>
26 </body>
27 <script src="../js/print.js" type="text/javascript"></script>
28  <script type="text/javascript">
29 var HKEY_Root,HKEY_Path,HKEY_Key;
30 HKEY_Root="HKEY_CURRENT_USER";
31 HKEY_Path="\\Software\\Microsoft\\Internet Explorer\\PageSetup\\";
32 //设置网页打印的页眉页脚为空
33 function PageSetup_Null()
34 {
35      try
36      {
37           var Wsh=new ActiveXObject("WScript.Shell");
38           
39           HKEY_Key="header";
40           Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"");
41           HKEY_Key="footer";
42           Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"");
43           
44           HKEY_Key="margin_left"     
45           Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,0);

47           HKEY_Key="margin_top"     
48           Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,0);

59      } 
60     catch(e)
61     {}
62 }
63 </script>
64 </html>

3、在你所要打印的页面加上打印的按钮,

<a id="btPrint" href="javascript:void(0)" title="打印报批件" onclick="printGroup();" class="linkbutton">【打 印】</a>

4、点击打印后会调用printGroup()方法,该方法写在同一文档的JS中

   function printGroup()
    {
        openPrintDocument(groupId,"group");
    }
function openPrintDocument(activityId,type)
{
    window.open("../ForeignActivity/documentprint.aspx?a="+Math.random()+"&id="+activityId+"&type="+type,"",width=820,height=750,left=50,top=50,menubar=yes,scrollbars=yes,resizable=yes,help=no,status=no;,true);
}

5、这里所打开的documentprint.aspx文件也就是我们之前准备好的通用模版文件,在显示这个文件之前我们必须要获取另一个我们准备好的模版文件group_O_train.html,将这个文件追加到<div id="pPrintContent" runat="server">标签中

1)documentprint.aspx.cs 中 page_Load()中的代码:

1 protected void Page_Load(object sender, EventArgs e)
2     {
3         btprinttmember.Visible = false;
4         IPrintable print = new DocumentPrint(GetDocument());
5         pPrintContent.InnerHtml = print.Print();
6 
7     }
View Code

2)在1)调用的GetDocument()方法获取文档

    {
        IOutPutWithTemplate one=null;
        string type = GetDocumentTypeName();

3) 在2)中调用GetDocumentTypeName()方法获取文档类型,类弄为“group”

技术分享
private string GetDocumentTypeName()
    {
        return Request.Params["type"];
    }
View Code

4) 在2)中调用GetDetailGroupInfoById(Id)方法,根据ID号获取到Group表的数据

5) 在2)中调用PrintApprovalSolutionDecorator(group2)方法是对这些数据进行处理,也就是去填充模版

  在这个类中首先要确定这个模版文件的名称,这里确定的是group_O_train.html文件

6)读文件

技术分享
/// <summary>
        /// 按照对象的类型名称来获取模版,规则是打开 对象类型名称.html文件,读取其中的内容
        /// </summary>
        /// <param name="type">类型名称(字符串,比如:group,budget)</param>
        /// <returns></returns>
        static public string GetTemplateFromFile(string type)
        {
            string fileName = HttpContext.Current.Server.MapPath("../Template/" +type+ ".html");
            return ReadTemplateFromFile(fileName);
        }

        /// <summary>
        /// 读取文件
        /// </summary>
        /// <param name="fileName"></param>
        /// <returns></returns>
        static private string ReadTemplateFromFile(string fileName)
        {
            if (!File.Exists(fileName))
            {
                throw new ApplicationException(fileName + "不存在");
            }
            System.Text.StringBuilder rtn = new System.Text.StringBuilder();
            using (StreamReader sr = File.OpenText(fileName))
            {
                String input;
                while ((input = sr.ReadLine()) != null)
                {
                    rtn.Append(input);
                }
                sr.Close();
            }
            return rtn.ToString();
        }

7)在1)中调用Print()方法是它会去调OutPut(string template)方法

技术分享
string IPrintable.Print()
        {
            return document.OutPut(this.Template);
        }
View Code

OutPut(string template)方法是IOutPutWithTemplate的一个接口

8)在类PrintApprovalSolutionDecorator中实现了OutPut(string template)方法,在这个方法中对模版文件中的占位符进行了替换

9)在1)中pPrintContent.InnerHtml = print.Print();就是将group_O_train.html追加到DocumentPrint.aspx中,最后将DocumentPrint.aspx页面展示出来,也就是我们要打印的页面。

c# 网页打印全流程
