在c#.net中合并字节数组 [英] Merging Byte arrays in c#.net

问题描述

我的表中有一列名为imageApplicant的image数据类型.我在此列中插入以字节形式存储的图像.我想将此列的内容呈现为pdf.为此，我循环遍历表中的行数并读取字节数组并创建pdf.对于表中的每条记录，我都会得到一个pdf.
我的问题是，现在我想以单个pdf呈现所有图像(而不是每个记录都为pdf)
为此，我必须合并ImageApplicant列的内容(字节数组)，我不知道该怎么做，这是什么最佳解决方案...

Hi I have a column in my table named ImageApplicant of image datatype . I insert image that are stored in form of bytes in this column. I want to render content of this column as pdf. for this i loop through number of rows in my table and read byte array and create pdf. For each record in my table i am getting one pdf.
My problem is that now i want to render all images in SINGLE pdf( not a pdf for each record)
for that i have to merge content(byte array) of ImageApplicant column i dont know how to do that is there any best solution for that...

推荐答案

您可以通过查找答案如何将数组中的2个或更多字节项合并到一个字节元素 [

You can find the answers over How to merge 2 or more byte items in array to one byte element[^].

ColinE写道:

要实现所需的功能，请将每个字节数组反序列化为合适的PDF表示形式，而不是使用合适的API将文档合并在一起.

To achieve what you require, deserialize each byte array into a suitable PDF representation, than use a suitable API to merge the documents together.
