问题描述

我真的很喜欢C#中的pdfclown,但是我想从byte []数组或文件流中打开pdf。我没有找到有关pdfclown的任何示例。有人可以帮忙吗?

I am really liking pdfclown in c# but I would like to open a pdf from a byte[] array or filestream. I have not found any examples of this for pdfclown. Could anyone help?

示例如下:

使用(org.pdfclown.files.File文件=新的org.pdfclown.bytes.IInputStream(bytes))
{

using (org.pdfclown.files.File file = new org.pdfclown.bytes.IInputStream(bytes)){

...
}

...}

谢谢

推荐答案

这是从字节数组中打开文件的正确方法:

This is the right way to open a file from a byte array:

var bytes = . . .;
using (var file = new org.pdfclown.files.File(new org.pdfclown.bytes.Buffer(bytes)))
{
}

如果您(0.1.2.1版或更高版本)或下载下一个版本,您甚至可以使用以下超简单的构造函数:

If you check out PDF Clown from its repository (version 0.1.2.1 or later) or download the next release, you can even use this ultra-simple constructor:

byte[] bytes = . . .;
using (var file = new org.pdfclown.files.File(bytes))
{
}

,或者对于System.IO.Stream:

or, in case of System.IO.Stream:

System.IO.Stream stream = . . .;
using (var file = new org.pdfclown.files.File(stream))
{
}

如果您具有纯文件系统路径,则为您的构造函数:

If you have a plain file system path, this is your constructor:

string filename = . . .;
using (var file = new org.pdfclown.files.File(filename))
{
}
