我是靠谱客的博主义气店员，最近开发中收集的这篇文章主要介绍利用ASP.NET实现web套打，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

最近，要把一个C/S结构的程序改成B/S结构。其中就遇到了打印的问题。研究了一下，web下打印方法大概有这么几种：

1、利用IE直接打印，这种方式最方便，但是控制能力较差。

2、利用ACTIVE控件，可以自己做一个IE的控件来控制打印。

3、水晶报表等第三方工具，购买价格昂贵。

根据我的需求情况，用IE直接打印的方式可以满足。我们的目的就是在一张申请表格上对应位置打印上相应的项目，表格也只有一页，不涉及分页的问题。

先来看一下表格，目的就是在一个WEBFORM里面对应的TEXTBOX内容放到对应的位置打印出来。

先来说一下我的思路：程序自动生成一个要打印的网页，将对应的字段值传递给这个网页，每个字段的位置事先量好，利用<div style=" ">来控制对应字段在页面中的位置。具体要到了下面技术：

1、自定义一个打印类，用来自动生成要打印的网页。

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Text;
using System.IO;
using System.Collections;

///

/// MyPrint 的摘要说明
///

public class MyPrint : System.Web.UI.Page
{
    public static string pageUrlBase;//Page基本的URL
    public string name;
    public string sex;
    public string brithday;
    public string country;
    public string CardName;
    public string CardNum;
    public string address;
    public string touchAddress;
    public string tel;
    public string postCode;
    public string type;
    public string reg;
    public string oldReg;
    ///

public void ClearView()
    {
        StringBuilder htmltext = new StringBuilder();
        try
        {
            if (!File.Exists(Server.MapPath(Context.Request.ApplicationPath) + "//printwindow.htm"))
            {
                FileStream fs = File.Create(Server.MapPath(Context.Request.ApplicationPath) + "//printwindow.htm");
                fs.Close();
            }
            using (StreamWriter sw = new StreamWriter(Server.MapPath(Context.Request.ApplicationPath) + "//printwindow.htm",false,Encoding.Default))

                else if (type == "增加准驾车型")
                {
                    sTableTitle = sTableTitle + "<img src=/"Images/1234.jpg/" Style=/"z-index: 115; left: 118px; position: absolute; top: 384px/" Width=/"8px/" Height=/"8px/" />";
                    sTableTitle = sTableTitle + "<div Style=/"z-index: 111; left: 600px; position: absolute; top: 352px/">" + oldReg + "</div>";
                }
                else if (type == "持军警驾驶证")
                {
                    sTableTitle = sTableTitle + "<img src=/"Images/1234.jpg/" Style=/"z-index: 114; left: 118px; position: absolute; top: 409px/" Width=/"8px/" Height=/"8px/" />";
                    sTableTitle = sTableTitle + "<div Style=/"z-index: 111; left: 600px; position: absolute; top: 352px/">" + oldReg + "</div>";

                }
                else
                {
                    sTableTitle = sTableTitle + "<img src=/"Images/1234.jpg/" Style=/"z-index: 116; left: 119px; position: absolute; top: 439px/" Width=/"8px/" Height=/"8px/" />";
                    sTableTitle = sTableTitle + "<div Style=/"z-index: 111; left: 600px; position: absolute; top: 352px/">" + oldReg + "</div>";

                }
                //输出身份证
                int length = CardNum.Length;
                int start = 272;
                for (int i = 0; i < length; i++)
                {
                    sTableTitle = sTableTitle + "<div Style=/"z-index: 105; left: " + start.ToString() + "px; position: absolute; top: 200px/">" + CardNum.Substring(i,1) + "</div>";
                    start = start + 18;
                }
                sTableTitle = sTableTitle + "</body>/n";
                sTableTitle = sTableTitle + "</html>/n";
                sw.WriteLine(sTableTitle);
                sw.Flush();
                sw.Close();
            }
        }
        catch
        {
            Response.Write("<script>alert('读取文件出错！')</script>");
        }
    }
public MyPrint()
{
//
// TODO: 在此处添加构造函数逻辑
//
        try
        {
            string urlSuffix = Context.Request.Url.Host;
            urlSuffix = urlSuffix + (Context.Request.Url.Port.ToString() == "" ? "" : ":" + Context.Request.Url.Port);
            urlSuffix = urlSuffix + (Context.Request.ApplicationPath.ToString() == "/" ? "" : Context.Request.ApplicationPath);
            pageUrlBase = @"http://" + urlSuffix;
        }
        catch
        {

        }
}
}

ClearView函数是用来自动生成网页。里面输出身份证的时候，为了和表格对应精确采用了按位输出。

2.调用的方法

   print.name = this.TextBox2.Text;
        if (RadioButton1.Checked)
            print.sex = "男";
        else
            print.sex = "女";
        print.brithday = this.TextBox4.Text;
        print.tel = this.TextBox5.Text;
        print.country = this.DropDownList2.Text;
        print.type = this.DropDownList3.Text;
        print.oldReg = this.DropDownList4.Text;
        print.reg = this.DropDownList6.Text;
        print.address = this.TextBox13.Text;
        print.touchAddress = this.TextBox14.Text;
        print.CardName = "身份证";
        print.CardNum = this.TextBox3.Text;

        print.ClearView();
        string showOpen = "<script lanage='javascript'>window.open('printwindow.htm','_blank');</script>";
        ScriptManager.RegisterClientScriptBlock(this.Button4, this.GetType(), "verygood", showOpen, false);
      这是提交页面上的一个“打印”按钮的响应事件。首先把页面上对应的字段传给打印类，然后调用ClearView来生成网页。最后，通过注册脚本的方式在新窗口中打开网页。我这里了AJAX所以用到了

ScriptManager.RegisterClientScriptBlock(this.Button4, this.GetType(), "verygood", showOpen, false);这句，如果没用AJAX用这个就可以了

RegisterClientScriptBlock("clientScript", showOpen);

3、用到的JAVASCRIPT

打印之后能够自动关闭窗口。

这样就基本实现了web套打。程序参考了 http://www.cnblogs.com/HelloSnoopy/articles/105475.html这篇文章。
