更换一个特定的十六进制在C＃中的偏移 [英] Replacing a specific hex offset in C#

问题描述

我怎么会去更换一个特定的十六进制二进制文件用C＃抵销的内容？

How would I go about replacing the content of a specific hex offset in a binary file with C#?

为了使它更清晰，可以说我的偏移量为0x33347和它的内容是06.我想改变06至17.怎样做到这一点？我有一个十六进制编辑经验非常少，所以我是不是真的能够计算出任何东西我自己，我有点失去了。

To make it more clear, lets say my offset is 0x33347, and the content of it is 06. I would want to change 06 to 17. How do I do this? I have very little experience with hex editing, so I weren't really able to figure anything out myself, I'm kind of lost.

推荐答案

使用 的FileStream ，将位置，然后写入字节。

Using a FileStream, set the Position of the stream to the offset, then write the byte.

这将覆盖当前的内容与你想要的东西。

This will overwrite the current content with what you want.

using(var fs = new FileStream("path to file", 
                              FileMode.Open, 
                              FileAccess.ReadWrite))
{
    fs.Position = 0x33347;
    fs.WriteByte(Convert.ToByte(0x6));
}
