net导出pdf文件

① 如何把要打印的网页导出成pdf文件

1、首先用chrome浏览器打开一个网页，如图所示。

② 关於asp.net 把网页内容导出为PDF文件

有个叫ITextsharp的开源dll，如果只是简单的报表可以满足你的要求，对于html支持不怎么好

③ asp.net中，gridview中的数据能不能导出成pdf格式的文件

asp.net中，gridview中的数据能不能导出成pdf格式的文件
本题只问最终结果？
结果是：
能

④ .net中如何将网页中的数据导出成pdf文件

可以用水晶报表啊

⑤ asp.net中，gridview中的数据能不能导出成pdf格式的文件

system.web.ui.control
ctl=this.datagrid1;
//datagrid1是你在窗体中拖放的控件
httpcontext.current.response.appendheader("content-disposition","attachment;filename=excel.xls");
httpcontext.current.response.charset
="utf-8";
httpcontext.current.response.contentencoding
=system.text.encoding.default;
httpcontext.current.response.contenttype
="application/ms-excel";
ctl.page.enableviewstate
=false;
system.io.stringwriter
tw
=
new
system.io.stringwriter()
;
system.web.ui.htmltextwriter
hw
=
new
system.web.ui.htmltextwriter
(tw);
ctl.rendercontrol(hw);
httpcontext.current.response.write(tw.tostring());
httpcontext.current.response.end();

⑥ vb.net 导出PDF

利用DataWindow.net在 vb.net 下导出PDF格式文件
利用datawindow.net，导出PDF文件，实现前提：
1.安装Acrobat Distiller虚拟打印机,注意要用datawindow.net提供的打印驱动，在c:\program files\sybase\datawindow.net2.0\driver中,在文章最后，我会提供一个静态安装虚拟打印机的批处理文件，方便安装。
2.安装Ghostscript 7.05 ，在网上找,免费的。
3.导出PDF文件前，一要指定虚拟打印机名，其次导出格式为PDF（Export.PDF.Method=Distill!）,另外还要指定 PDF.Distill.CustomPostScript=Yes。
具体代码如下：
''' <summary>
''' 导出文件
''' </summary>
''' <param name="sender"></param>
''' <param name="e"></param>
''' <remarks></remarks>
Private Sub btnExport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExport.Click
Try
Dim strFilename, strPrinter As String
Dim saveDg As New SaveFileDialog
strPrinter = Me.dwPrint.Describe("DataWindow.Print.PrinterName")
saveDg.FileName = Me.dwPrint.Tag.ToString
saveDg.Filter = "Pdf文件|*.pdf|Excel文件|*.xls|所有文件|*.*"
If saveDg.ShowDialog = Windows.Forms.DialogResult.OK Then
strFilename = saveDg.FileName
If strFilename.IndexOf(".pdf") > 0 Then
Me.dwPrint.Modify("DataWindow.Print.PrinterName='Acrobat Distiller'")
Me.dwPrint.Modify("DataWindow.Export.PDF.Method=Distill!")
Me.dwPrint.Modify("DataWindow.Export.PDF.Distill.CustomPostScript=Yes")
Me.dwPrint.SaveAs(strFilename, Sybase.DataWindow.FileSaveAsType.Pdf, True)
ElseIf strFilename.IndexOf(".xls") > 0 Then
Me.dwPrint.SaveAs(strFilename, Sybase.DataWindow.FileSaveAsType.Excel, True)
End If
Me.dwPrint.Modify("DataWindow.Print.PrinterName='" + strPrinter + "'")
MessageBox.Show("导出成功!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
Catch ex As Exception
MessageBox.Show(ex.Message, "提示", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub

4 批处理文件（实现静默安装）

⑦ 怎样把.net页面中的表格转换成pdf

安装Adobe Acrobat软件，安装成功后网页有个“将网页转换为PDF”的插件功能，能将任何网页及文档转成PDF文档。

⑧ 如何用.NET将DWG文件打印为PDF

因为有人问到，所以写了个例子。具体的要求是从.NET(比如C#)里面调用AutoCAD ActiveX API实现后台打印DWG文件为PDF文件，而且要把打印页面的大小设置成和DWG视图的页面的大小一致。当然除了ActiveX API，其它接口，比如ObjectARX和AutoCAD.NET API也支持打印并能实现上述功能的。不过我们今天就限定一下范围，用一用ActiveX API，而且指定产品是AutoCAD 2010吧。
执行步骤：打开一个dwg文件，用netload加载下面代码所在的.dll文件，再输入命令plottest，就得到输出结果（一个.pdf文件）。

⑨ .net打印pdf文件

方法一（web）：window.print()

    print()方法是浏览器打印功能的一种程序调用。print方法用于打印当前窗口的内容。

打印当前页：

function printPage(){

    window.print();

}

打印局部页面：

        前端页面：<iframe style="width:100%;height:100%;" id="fileId" src="文件路径">

        </iframe>

        <input type="button" name="print" id="print" value="打印" />

        js:$("#print").click(function () {

        var iframe = document.getElementById("fileId");

        iframe.contentWindow.print();

    });

方法二：调用系统API（得保证本地装有相关的软件）

PrintDocument pd = new PrintDocument();

            pd.PrinterSettings.PrinterName = "Microsoft Print to PDF";

            Process p = new Process

            {

                StartInfo = new ProcessStartInfo

                {

                    CreateNoWindow = false,

                    WindowStyle = ProcessWindowStyle.Hidden,

                    UseShellExecute = true,

                    FileName = filePath,//文件路径

                    Verb = "print",

                    Arguments = @"/p /h \" + filePath + "\"\"" + pd.PrinterSettings.PrinterName + "\""

                }

            };

            p.Start();

            p.WaitForExit();

方法三：spire打印方式（收费）下面是简单的使用例子

 var pdf = new PdfDocument(filePath);

//设置打印机

pdf.PrintSettings.PrinterName = "Microsoft Print to PDF";

pdf.print();

方法四：安装RawPrint

var printer = new Printer();

var file = File.Open(filePath, FileMode.Open);

byte[] array = new byte[file.Length];

file.Read(array, 0, array.Length);

printer.PrintRawStream(printerName, file, "打印机上显示的任务名");

file.Close();

printer.PrintRawFile(printerName, fileFullPath, "打印机上显示的任务名");

这个测试时虚拟打印机上正常，使用公司打印机时出现乱码问题以及打印任务不停的问题
