问题描述
我想一个字节数组追加到一个已存在的文件(C:\\ test.exe的)
。假设以下字节数组:
I would like to append a byte array to an already existing file (C:\test.exe)
. Assume the following byte array:
byte[] appendMe = new byte[ 1000 ] ;
File.AppendAllBytes(@"C:\test.exe", appendMe); // Something like this - Yes, I know this method does not really exist.
我会做到这一点使用File.WriteAllBytes,但我将使用一个巨大的字节数组,System.MemoryOverload例外不断被抛出。所以,我很可能会到大阵分割成块,每个字节数组追加到文件的末尾。
I would do this using File.WriteAllBytes, but I am going to be using an ENORMOUS byte array, and System.MemoryOverload exception is constantly being thrown. So, I will most likely have to split the large array up into pieces and append each byte array to the end of the file.

推荐答案
一个方法是创建一个的与<$c$c>FileMode.Append$c$c>创建模式。
One way would be to create a FileStream
with the FileMode.Append
creation mode.
打开该文件,如果它存在,并寻求到该文件的末尾,或
创建一个新的文件。
这看起来是这样的:
public static void AppendAllBytes(string path, byte[] bytes)
{
//argument-checking here.
using (var stream = new FileStream(path, FileMode.Append))
{
stream.Write(bytes, 0, bytes.Length);
}
}
