Pechkin 是GitHub上的一個開源項目，可方便將html轉化成pdf文檔，使用也很方便，下面是winform項目中的示例代碼：using?System;

using?System.Diagnostics;

using?System.Drawing.Printing;

using?System.IO;

using?System.Windows.Forms;

using?Pechkin;

using?Pechkin.Synchronized;

namespace?PdfTest

{

public?partial?class?Form1?:?Form

{

public?Form1()

{

InitializeComponent();

}

private?void?btnCreatePDF_Click(object?sender,?EventArgs?e)

{

SynchronizedPechkin?sc?=?new?SynchronizedPechkin(new?GlobalConfig()

.SetMargins(new?Margins()?{?Left?=?0,?Right?=?0,?Top?=?0,?Bottom?=?0?})?//設置邊距

.SetPaperOrientation(true)?//設置紙張方向為橫向

.SetPaperSize(ConvertToHundredthsInch(50),?ConvertToHundredthsInch(100)));?//設置紙張大小50mm?*?100mm

byte[]?buf?=?sc.Convert(new?ObjectConfig(),?this.txtHtml.Text);

if?(buf?==?null)

{

MessageBox.Show("Error?converting!");

return;

}

try

{

string?fn?=?Path.GetTempFileName()?+?".pdf";

FileStream?fs?=?new?FileStream(fn,?FileMode.Create);

fs.Write(buf,?0,?buf.Length);

fs.Close();

Process?myProcess?=?new?Process();

myProcess.StartInfo.FileName?=?fn;

myProcess.Start();

}

catch?{?}

}

private?int?ConvertToHundredthsInch(int?millimeter)

{

return?(int)((millimeter?*?10.0)?/?2.54);

}

}

}

web項目中也可以使用:

1.??新建一個待打印的頁面，比如index.htm，示例內容如下:html>

html打印測試

*?{?margin:0;?padding:0;?font-size:12px?}

table?{?margin:10px;?border:2px?solid?#000;?border-collapse:collapse;?margin:5px?auto?}

th,?td?{?border:1px?solid?#000;?border-collapse:collapse;?padding:3px?5px?}

h1?{?font-size:24px?}

@media?print?{

.no-print?{?display:?none;?}

.page-break?{?page-break-after:?always;?}

}

function?createPdf()?{

window.open("CreatePdf.ashx?html=index.htm");

}

導出pdf

XXXX報表

?序號??欄目1??欄目2??欄目3??欄目4??1??數據1??數據2??數據3??數據4??2??數據1??數據2??數據3??數據4??3??數據1??數據2??數據3??數據4??4??數據1??數據2??數據3??數據4??5??數據1??數據2??數據3??數據4??合計：????300.00??300.00?

2、創建一個ashx來生成并輸出pdfusing?System;

using?System.Drawing.Printing;

using?System.IO;

using?System.Web;

using?Pechkin;

using?Pechkin.Synchronized;

namespace?PdfWebTest

{

///?

///?Summary?description?for?CreatePdf

///?

public?class?CreatePdf?:?IHttpHandler

{

public?void?ProcessRequest(HttpContext?context)

{

string?htmlFile?=?context.Request["html"];

if?(!string.IsNullOrWhiteSpace(htmlFile))

{

string?filePath?=?context.Server.MapPath(htmlFile);

if?(File.Exists(filePath))

{

string?html?=?File.ReadAllText(filePath);

SynchronizedPechkin?sc?=?new?SynchronizedPechkin(new?GlobalConfig()

.SetMargins(new?Margins()?{?Left?=?0,?Right?=?0,?Top?=?0,?Bottom?=?0?})?//設置邊距

.SetPaperOrientation(true)?//設置紙張方向為橫向

.SetPaperSize(ConvertToHundredthsInch(50),?ConvertToHundredthsInch(100)));?//設置紙張大小50mm?*?100mm

byte[]?buf?=?sc.Convert(new?ObjectConfig(),?html);

if?(buf?==?null)

{

context.Response.ContentType?=?"text/plain";

context.Response.Write("Error?converting!");

}

try

{

context.Response.Clear();

//方式1：提示瀏覽器下載pdf

//context.Response.AddHeader("content-disposition",?"attachment;filename="?+?htmlFile?+?".pdf");

//context.Response.ContentType?=?"application/octet-stream";

//context.Response.BinaryWrite(buf);

//方式2：直接在瀏覽器打開pdf

context.Response.ContentType?=?"application/pdf";

context.Response.OutputStream.Write(buf,?0,?buf.Length);

context.Response.End();

}

catch(Exception?e)?{

context.Response.ContentType?=?"text/plain";

context.Response.Write(e.Message);

}

}

}

}

public?bool?IsReusable

{

get

{

return?false;

}

}

private?int?ConvertToHundredthsInch(int?millimeter)

{

return?(int)((millimeter?*?10.0)?/?2.54);

}

}

}

注意事項：部署web項目時，要保證bin目錄下有以下相關dll文件

Common.Logging.dll

libeay32.dll

libgcc_s_dw2-1.dll

mingwm10.dll

Pechkin.dll

Pechkin.Synchronized.dll

ssleay32.dll

wkhtmltox0.dll

打開App，閱讀手記
