ASP.NET MVC 5在浏览器中从字节[]C呈现PDF#

pdf asp.net-mvc asp.net c#

我正在与Kendo MVC合作,我想将上载的PDF呈现到Tabstrip中。

当获取要在选项卡中显示的PDF文件时,我将调用我的控制器和后续服务,以字节数组的形式获取文件数据,并使用以下代码将数据返回到其各自的DIV中。

public FileStreamResult GetRxPdf(int prescriptionId)
{
    var retVal = _service.GetRxPdf(prescriptionId);
    byte[] byteArray = retVal.FileData;
    MemoryStream pdfStream = new MemoryStream();
    pdfStream.Write(byteArray, 0, byteArray.Length);
    pdfStream.Position = 0;
    return new FileStreamResult(pdfStream, retVal.ContentType);
}

呈现的输出不是PDF,但如下所示

%PDF-1.7%\239;\239;\\\239;\\239;\\239;\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\.32 841.92]/目录4 0 R/结构父级0>>endobj 4 0 obj <> stream xï¿½ï¿½]Ysï¿½F~Wï¿½ï¿½É5ï¿½\ï¿½Iï¿½Öï¿½ï¿½[9[ï¿½yHï¿½@Sï¿½Ì²ï¿½ï¿½ï¿½ï¿½ï¿½7ï¿½ï¿½ï¿½=Ipï¿½ï¿½Pï¿½TEï¿½ï¿½3ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½1ï¿½>[,ï¿½ï¿½&ï¿½eï¿½ï¿½7ï¿½Ïï¿½ï¿½ï¿½ï¿½ï¿½_?½_?½_?½_?½_?½_?½_?½_??\\239;\239;\239;\239;\\239;\\\\\\239;\\\239;\\239;\\\\\\\\239;\\\\\\\\美元?.I8+jAIÃï¿½ï¿½ï¿½ï¿½×¯ï¿½ï¿½ã£³ï¿½ï¿½Óï¿½ï¿½ï¿½ï¿½ï¿½ï¿½|w|ï¿½ï¿½eAï¿½Hï¿½Dï¿½ï¿½ï¿½ï¿½uqy3ï¿½ï¿½ï¿½ï¿½ï¿½Fï¿½ï¿½ï¿½ï¿½ï¿½ï¿½G/`ï¿½/ï¿½Gï¿½ï¿½mï¿½ï¿½ï¿½ï¿½ï¿½4rï¿½gï¿½ï¿½ï¿½ï¿½mï¿½* ï¿½ï¿½/s^%ï¿½HQï¿½Rï¿½]äï¿½ï¿½ï¿½ï¿½]ï¿½ï¿½h1S>ï¿½Wï¿½ï¿½ï¿½ï¿½ï¿½ï¿½R^ï¿½0>ï¿½ï¿½ï¿½Õï¿½Q1(ï¿½'lï¿½zLï¿½ï¿½ï¿½z>æ£ï¿½ï¿½pm0ï¿½ï¿½ï¿½ï¿½=ï¿½Â±7ï¿½;ï¿½ï¿½ ?_?_?_?_?_?_?_??_?_?_?_?_?_?_?_?_?_?_?A+_?_?xd%_?_?_?_?_?_?_?_?_?_?? _?_?½$MD_?½~ _?½A2V6_?½_?½_?½Q…。此处有更多文件数据… 0000166807 00000n拖车<]gt;>开始xref 166853%%eof

当数据通过Ajax调用返回时,它就是这样传递给DIV的。

 $("#divRxPdf").html(data);

如果有人能帮助我,并在分区中相应地显示PDF,我将不胜感激。

更新:

PDF需要嵌入到HTML中 <embed> 或 <iframe> . 您还可以使用库,例如 pdf.js 使用某些控件呈现PDF文件。

pdf.js自述文件包含示例以及如何: https://github.com/mozilla/pdf.js

通过使用 retun File() 方法

public ActionResult GetRxPdf(int prescriptionId)
 {
    var retVal = _service.GetRxPdf(prescriptionId);
    byte[] byteArray = retVal.FileData;      
   return File(byteArray , "application/pdf" , "Filename.pdf");
}

您可以使用对象标记来实现它。

$obj = $('<object>'); 
$obj.attr("data","Url to PDF");
$obj.attr("type","application/pdf");

$("#pdfdiv_content").append($obj);
