c# 网页打印全流程
时间：2022-03-18 05:11
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
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" cellspacing=0 cellpadding=3px border=1 bordercolor=black>
4 <thead 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" %>
2
3 <html xmlns="http://www.w3.org/1999/xhtml" >
4 <head runat="server">
5 <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
6
7 <title>打印</title>
8 <link href="../css/print.css" rel="stylesheet" type="text/css" />
9 </head>
10 <body onload="PageSetup_Null()">
11 <form id="form1" runat="server">
12 <object id="WebBrowser" width=0 height=0 classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2">
13 </object>
14 <div class="printbar">
15 <div onclick="print()"><img src="../images/printbutton.gif" border=0 / alt="打印"></a>
17 <a href="javascript:void(0)" onclick="printtrainmember()" runat="server" id="btprinttmember"><img src="../images/printbutton.gif" border=0 / alt="打印培训人员" ></a>
18 <a href="javascript:void(0)" onclick="printPreview()" ><img src="../images/printpreviewbutton.gif" border=0 / alt="打印预览"></a>
19 <a href="javascript:void(0)" onclick="window.close()"><img src="../images/closebutton.gif" border=0 / alt="打印"></a>
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);

50 HKEY_Key="margin_right"
51 Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,0);

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

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
private IOutPutWithTemplate GetDocument()
{
IOutPutWithTemplate one=null;
string type = GetDocumentTypeName();
type = type.ToLower();
switch (type)
{
case "rwpj":

break;

break;
//case "zsgroups":

// break;
case "zspj":

break;

3) 在2）中调用GetDocumentTypeName()方法获取文档类型，类弄为“group”
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
/// <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();
}
View Code
7）在1）中调用Print()方法是它会去调OutPut(string template)方法
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。
