问题描述

如何使用c＃代码将文件流中的数据转换为pdf，并使用c＃代码和

下载。



我尝试过：

 byte [] fileContents = Docx（）; 
 using（FileStream file = new FileStream（wordPath，FileMode.Create））
 {
 file.Write（fileContents，0，fileContents.Length）; 
 file.Close（）; 
} 
 

i希望将fileContents中的数据转换为pdf

解决方案

你不能 - 或者至少不能在合理的时间范围内。

DOCX是一种基于Zipped XML的文档格式，PDF与它完全不同。

您不能将原始DOCX作为字节流并说这是PDF - 您必须将DOCX文件处理为文档并将该文档重新解释为PDF文件。 />


使用插件或API - 尝试自己动手并不是一个好主意，因为文档格式不是很简单所以涉及太多理解和处理。

这是可能的，但你需要第三方库。在这种情况下，您的代码可能如下所示：

  byte  [ ] fileContents = Docx（）; 
 使用（FileStream file =  new  FileStream（wordPath，FileMode.Create））
 {
 file.Write（fileContents， 0 ，fileContents.Length）; 
 file.Close（）; 
} 
 
  //  构造函数的虚拟对象，因为你不会在外面合并数据 
 对象 myDataObject =  new  对象（）; 
 
 DocumentGenerator dg =  new  DocumentGenerator（myDataObject）; 
 MemoryStream outputDocumentStream =  new  MemoryStream（）; 
 dg.GenerateDocument（file，outputDocumentStream，Pdf）;

What I have tried:

byte[] fileContents = Docx();
         using (FileStream file = new FileStream(wordPath, FileMode.Create))
         {
             file.Write(fileContents, 0, fileContents.Length);
             file.Close();
         }

i want to convert the data in fileContents to pdf

解决方案

You can't - or at least not in a reasonable time frame.
DOCX is a Zipped XML based document format, PDF is nothing like it.
You can't just take a "raw" DOCX as a stream of bytes and say "this is a PDF" - you have to process the DOCX file into a document and reinterpret that document as a PDF file.

Use a plug in, or an API - it really isn't a good idea to try and do it yourself, there is just too much involved as neither document format is trivial to understand and process.

It is possible, but you will need 3rd party library. In that case your code could look like this:

byte[] fileContents = Docx();
using (FileStream file = new FileStream(wordPath, FileMode.Create))
{
	file.Write(fileContents, 0, fileContents.Length);
	file.Close();
}

// dummy object for constructor, since you will not merge outside data
object myDataObject = new object();

DocumentGenerator dg = new DocumentGenerator(myDataObject); 
MemoryStream outputDocumentStream = new MemoryStream(); 
dg.GenerateDocument(file, outputDocumentStream, Pdf);
