推荐答案

有两种可能:

There are two possibilities:

1. 将文件转换为十六进制编码的字节字符串，并使用它
2. 将文件位置作为字符串(可能作为CDATA项目

1. Convert your file into a hexadecimal encoded byte string, and use that
2. Insert the file location as a string possibly as a CDATA item

)插入 选项2更合适，因为它将减少XML中的数据量.但是，可能XML不是解决您问题的最佳解决方案.

Option 2 would be more appropriate as it would reduce the amount of data in the XML. However, it may be that XML is not the best solution to your problem.

如果您的目的是将多个文件保存在一起，以便轻松移动或访问相关文件，那么我个人会使用zip.如果有任何疑问，请参阅这篇文章
C#压缩文件和/或文件夹 [

if your purpose is to save multiple files together, making it easy to move or access related files, then I personally would use zip. If this has any interrest have a look at this article

最好的方法是读取文件的所有字节并进行转换按字节排列的数组到Base64，并将结果文本插入innertext.

byte [] bytes = System.IO.File.ReadAllBytes(filename);
字符串str = Convert.ToBase64String(bytes);

the best way is read all bytes of file and convert that array of byts to Base64 and insert result text into innertext.

byte[] bytes = System.IO.File.ReadAllBytes(filename);
String str = Convert.ToBase64String(bytes);
