                f.fFullName = pdffilename.FullName;
                f.fName = pdffilename.Name;
                f.FileSize = pdffilename.Length;
                f.fExtension = pdffilename.Extension;
                byte[] bytes = File.ReadAllBytes(pdffilename.FullName);

推荐答案

好的，所以那么为什么你的foreach循环创建一个fileatt对象，设置它的属性然后扔掉它？你没有对你刚创建的那个对象做任何事情。



另外，你的fileatt.fContent属性被输入为一个字符串，你得到的是byte [] ReadAllBytes不会转换为任何含义。您必须将该字符串更改为byte []才能使其有意义。

OK, so why then is your foreach loop creating a fileatt object, setting its properties and then throwing it away? You're not doing anything with that object you just created.

Also, your fileatt.fContent property is typed as a string, which the byte[] you get when you ReadAllBytes will not convert to with any meaning. You have to change that string to byte[] in order for it to make any sense.
