将字符串转换为PDF [英] Convert a string to PDF

问题描述

下午好世界。我正在开发一个VB net 2017程序来使用REST服务来生成PDF文件。



PDF带有属性pdf的字符串响应和用基数64编码。



我将尝试用指令解码字符串：



strPdf = New System.Text.ASCIIEncoding（）。GetString（Convert.FromBase64String（strWork_PDF））。



strWork_PDF是一个变量字符串，我已经拥有了编码信息。



更正：我的回复包含徽标和某种格式，所以也许它不是100％的字符串变量。



从那里，我需要创建PDF文件;我认为解码后的字符串包含正确的PDF格式，但我不对。我得到的PDF就像解码后的字符串一样，纯文本，完全没有格式，所以也许我需要一个模板，但除非我的供应商想把它交给我，否则我没有。< br $> b $ b

这就是我想要找到的，如何转换它。



I'我将非常感谢您寻求解决方案或进行调查的任何帮助或提示。



我的尝试：



我正在分析Itextsharp.dll组件以查看它是否适合我需要的内容。

Good Afternoon World. I'm developing a VB net 2017 program to consume a REST service to generate a PDF file.

The PDF comes in a string response with the attribute "pdf" and is encoded in base 64.

I'm going to try to decode the string with the instruction:

strPdf = New System.Text.ASCIIEncoding().GetString(Convert.FromBase64String(strWork_PDF)).

strWork_PDF is a variable string in which I already have the encoded information.

CORRECTION: My response includes a Logo and some kind of a format, so maybe it´s not a 100% string variable.

From there, I'll need to create the PDF file; I supposed the decoded string contains the right format for the PDF, but I was not right. The PDF I´m getting is just like the same as the decoded string, plain text, with no format at all, so maybe I need a template,but I don´t have it unless my vendor want to deliver it to me.

That´s what I´m trying to find out, how to convert it.

I´ll appreciate any help or tip about where to look for a solution or to investigate.

What I have tried:

I´m analyzing the Itextsharp.dll component to see if it suits what I need in the meantime.

推荐答案

A PDF文件不是字符串。它是一个字节序列。



如果您的响应包含Base64编码的PDF文件，您只需要将其转换回字节数组：

A PDF file is not a string. It is a sequence of bytes.

If your response contains a Base64-encoded PDF file, you just need to convert that back to an array of bytes:

Dim pdfBytes As Byte() = Convert.FromBase64String(strWork_PDF)
