netpdf_net如何將頁面生成pdf

❶ .net怎樣在網頁中打開pdf格式文件，不允許下載，只能在網頁中瀏覽，求大神

page.Response.AddHeader("Content-Disposition", "attachment;filename=" + downLoad + ".xls");
while (dataLength > 0 && page.Response.IsClientConnected)
{
int lengthRead = fs.Read(buffer, 0, Convert.ToInt32(ChunkSize));
page.Response.OutputStream.Write(buffer, 0, lengthRead);
page.Response.Flush();
dataLength = dataLength - lengthRead;
}
page.Response.Close();

這是導出xls的 "attachment;filename=" + downLoad + ".xls" 這是以附件的形式所以代開的時候是以下載流打開的
你不要用附件的形式，那麼它就不會允許下載
PDF document

<% response.ContentType ="application/pdf" %>
 這是網頁顯示pdf的網頁內容頭
還有以後問問題請上代碼

❷ net中怎麼打開指定路徑下的PDF文件

需要安裝adobereader

<objectclassid="clsid:CA8A9780-280D-11CF-A24D-444553540000"height="700px"width="755px">
<paramname="_Version"value="65539">
<paramname="_ExtentX"value="20108">
<paramname="_ExtentY"value="10866">
<paramname="_StockProps"value="0">
<paramname="SRC"value="D:TDDownloadAJAX實戰中文版AJAX實戰中文版AJAX實戰.pdf">
</object>

❸ 如何用.NET將DWG文件列印為PDF

執行步驟：打開一個dwg文件，用netload載入下面代碼所在的.dll文件，再輸入命令plottest，就得到輸出結果（一個.pdf文件）。

要用到的參考：

AcDbMgd.dll;AcMgd.dll;AutoCAD 2010 Type Library;System.Windows.Forms; AutoCAD/ObjectDBX Common 18.0 Type Library.

VB.NET:

Imports System

Imports Autodesk.AutoCAD.Runtime

Imports Autodesk.AutoCAD.Interop

Imports Autodesk.AutoCAD.Interop.Common

Imports Autodesk.AutoCAD.ApplicationServices

Imports Autodesk.AutoCAD.DatabaseServices

Imports Autodesk.AutoCAD.EditorInput

<Autodesk.AutoCAD.Runtime.CommandMethod("Plottest")> _

Public Sub PlotToPDF()

Dim activeDoc As Document = Application.DocumentManager.MdiActiveDocument

Dim ThisDrawing As AcadDocument = CType(activeDoc.AcadDocument, AcadDocument)

Dim layout As AcadLayout = ThisDrawing.ActiveLayout

Dim MediaName As String = layout.CanonicalMediaName

If MediaName.Equals("") Then

activeDoc.Editor.WriteMessage("There is no media set for the active layout.")

Return

Else

activeDoc.Editor.WriteMessage(("The media for the active layout is: " + MediaName))

End If

Try

Dim oplot As AcadPlotConfiguration = ThisDrawing.PlotConfigurations.Add("PDF", layout.ModelType)

oplot.PaperUnits = AcPlotPaperUnits.acMillimeters

oplot.StyleSheet = "monochrome.ctb"

oplot.PlotWithPlotStyles = True

oplot.ConfigName = "DWG To PDF.pc3"

oplot.UseStandardScale = True

oplot.StandardScale = AcPlotScale.acScaleToFit

oplot.PlotType = AcPlotType.acExtents

oplot.CenterPlot = True

Dim oMediaNames As Object = layout.GetCanonicalMediaNames

Dim mediaNames As ArrayList = New ArrayList(CType(oMediaNames, String()))

For Each sName As String In mediaNames

If sName.Contains(MediaName) Then

oplot.CanonicalMediaName = sName

layout.CopyFrom(oplot)

layout.PlotRotation = AcPlotRotation.ac0degrees

layout.RefreshPlotDeviceInfo()

ThisDrawing.SetVariable("BACKGROUNDPLOT", 0)

ThisDrawing.Plot.QuietErrorMode = True

ThisDrawing.Plot.PlotToFile("c:/temp/d1.pdf", "DWG To PDF.pc3")

oplot.Delete()

oplot = Nothing

Return

End If

Next

Catch es As System.Exception

System.Windows.Forms.MessageBox.Show(es.ToString)

End Try

End Sub

❹ .net如何將頁面生成pdf

using System;
using System.IO;
using System.Text;
using System.Collections;

namespace PDFGenerator
{

public class PDFGenerator
{
static float pageWidth = 594.0f;
static float pageDepth = 828.0f;

static StreamWriter pPDF=new StreamWriter("E:\\myPDF.pdf");

static MemoryStream mPDF= new MemoryStream();

static void ConvertToByteAndAddtoStream(string strMsg)
{

mPDF.Write(buffer,0,buffer.Length);
buffer=null;
}

static string xRefFormatting(long xValue)
{
string strMsg =xValue.ToString();
int iLen=strMsg.Length;
if (iLen<10)
{
StringBuilder s=new StringBuilder();
int i=10-iLen;
s.Append('0',i);
strMsg=s.ToString() + strMsg;
}
return strMsg;
}

static void Main(string[] args)
{
ArrayList xRefs=new ArrayList();
//Byte[] buffer=null;
float yPos =0f;
long streamStart=0;
long streamEnd=0;
long streamLen =0;
string strPDFMessage=null;
//PDF文檔頭信息
strPDFMessage="%PDF-1.1\n";
ConvertToByteAndAddtoStream(strPDFMessage);

xRefs.Add(mPDF.Length);
strPDFMessage="1 0 obj\n";
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage="<< /Length 2 0 R >>\n";
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage="stream\n";
ConvertToByteAndAddtoStream(strPDFMessage);
////////PDF文檔描述
streamStart=mPDF.Length;
//字體
strPDFMessage="BT\n/F0 " + fontSize +" Tf\n";
ConvertToByteAndAddtoStream(strPDFMessage);
//PDF文檔實體高度
yPos = pageDepth - pageMargin;
strPDFMessage=pageMargin + " " + yPos +" Td\n" ;
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage= leadSize+" TL\n" ;
ConvertToByteAndAddtoStream(strPDFMessage);

//實體內容
strPDFMessage= "(http://www.wenhui.org)Tj\n" ;
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage= "ET\n";
ConvertToByteAndAddtoStream(strPDFMessage);
streamEnd=mPDF.Length;

streamLen=streamEnd-streamStart;
strPDFMessage= "endstream\nendobj\n";
ConvertToByteAndAddtoStream(strPDFMessage);
//PDF文檔的版本信息
xRefs.Add(mPDF.Length);
strPDFMessage="2 0 obj\n"+ streamLen + "\nendobj\n";
ConvertToByteAndAddtoStream(strPDFMessage);

xRefs.Add(mPDF.Length);
strPDFMessage="3 0 obj\n<</Type/Page/Parent 4 0 R/Contents 1 0 R>>\nendobj\n";
ConvertToByteAndAddtoStream(strPDFMessage);

xRefs.Add(mPDF.Length);
strPDFMessage="4 0 obj\n<</Type /Pages /Count 1\n";
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage="/Kids[\n3 0 R\n]\n";
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage="/Resources<</ProcSet[/PDF/Text]/Font<</F0 5 0 R>> >>\n";
ConvertToByteAndAddtoStream(strPDFMessage);

ConvertToByteAndAddtoStream(strPDFMessage);

xRefs.Add(mPDF.Length);
strPDFMessage="5 0 obj\n<</Type/Font/Subtype/Type1/BaseFont/Courier/Encoding/WinAnsiEncoding>>\nendobj\n";
ConvertToByteAndAddtoStream(strPDFMessage);

strPDFMessage="xref\n0 7\n0000000000 65535 f \n";
for(int i=0;i<xRefs.Count;i++)
{
strPDFMessage+=xRefFormatting((long) xRefs[i])+" 00000 n \n";
}
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage="trailer\n<<\n/Size "+ (xRefs.Count+1)+"\n/Root 6 0 R\n>>\n";
ConvertToByteAndAddtoStream(strPDFMessage);

strPDFMessage="startxref\n" + streamStart+"\n%%EOF\n";
ConvertToByteAndAddtoStream(strPDFMessage);
mPDF.WriteTo(pPDF.BaseStream);

mPDF.Close();
pPDF.Close();
}
}

另外：C#中生成PDF文件的方法挺多，可以使用iTextSharp控制項，還有aspose的控制項也可以。這些控制項的功能都很強大，所以控制項的大小也會很大

❺ 在.net下如何提取PDF的文字並檢索相關數據

FileStream ReadPdf = new FileStream(@"d:\books\vb.net\test.pdf", FileMode.Open);
long FileSize;
FileSize = ReadPdf.Length;
byte[] Buffer = new byte[(int)FileSize];
ReadPdf.Read(Buffer, 0, (int)ReadPdf.Length);
ReadPdf.Close();

寫
FileStream CreatePdf = new FileStream(@"d:\books\vb.net\test1.pdf", FileMode.Create);
CreatePdf.Write(Buffer,0,Buffer.Length);
CreatePdf.Close();

希望能幫帶你的忙~告一段落~謝謝~

❻ 如何使用.net編程給pdf文件加水印（急）

我說錯了我用的itextsharp 是用於.net的現在的情況是找到了庫函數的寫法但老是報錯希望大俠們幫看一下：

PdfReader reader = new PdfReader("C:/Documents and Settings/zeng/桌面/test1.pdf");
PdfStamper stamp = new PdfStamper(reader, new FileStream("C:/Documents and Settings/zeng/桌面/test1.pdf", FileMode.Create));
int n = reader.NumberOfPages;
int i = 0;
PdfContentByte under;
iTextSharp.text.Image im = iTextSharp.text.Image.GetInstance("C:/Documents and Settings/zeng/桌面/logo.jpg");
im.SetAbsolutePosition(440, 730);
im.ScaleAbsolute(160, 60);

while (i < n)
{
i++;
under = stamp.GetOverContent(i);
under.AddImage(im);
}
-----以上都正確
stamp.Close(); ---此處報異常說文件在被另一個程序使用。
reader.Close();

看了半天沒發現哪裡有打開文件沒有關閉的真不知道該怎麼辦

❼ 在.NET中如何將pdf文件轉換成我word或者html。

這個基本上沒法做，要從程序上來說的話你得了解pdf和word的文件格式，太難。而且現在的商業軟體都很難解決這個問題。
不過有個簡單的方法就是利用online的service，網上有很多在線pdf轉word的，你可以在程序裡面與它們通信，提交pdf，下載word

❽ .net生成PDF文件的一個問題..

table.Padding = 0;
table.Spacing = 2; //設置這個值的大小可以解決這個問題

❾ 怎樣把.net頁面中的表格轉換成pdf

安裝Adobe
Acrobat軟體，安裝成功後網頁有個「將網頁轉換為PDF」的插件功能，能將任何網頁及文檔轉成PDF文檔。
