要读取字节文件，请使用以下代码:

To read a file in bytes use the following code :

byte[] bytes = File.ReadAllBytes("filename.ext");

现在，您可以对字节数组进行任何操作.

Now you can do what ever you want to the array of bytes.

为了读取字节，可以使用FileStream class.

Hi,
In order to read the bytes you can use FileStream class.

FileStream stream = new FileStream("pathtodoc.ext", FileMode.Open);
byte [] array = new byte[stream.Length];
int bytesread = stream.Read(array, 0, stream.Length);

为了将字节写回到流中，请使用Write 方法.

In order to write back the bytes into stream use Write method.

FileStream stream = new FileStream("pathtodoc.ext", FileMode.Create);
stream.Write(array, 0, stream.Length);
