将文件转换为二进制文件在C＃ [英] Convert file to binary in C#

问题描述

我试图写一个程序，通过传递一个声音文件（有点像一个传真）。我打破了我的程序分为以下几个步骤：

I am trying to write a program that transfers a file through sound (kind of like a fax). I broke up my program into several steps:

1. 将文件转换为二进制

1. convert file to binary

转换成1到一定的语气和0至另一个

convert 1 to a certain tone and 0 to another

播放铃声到另一台计算机

play the tones to another computer

其他电脑听铃声

其他电脑转换色调成二进制

other computer converts tones into binary

其他电脑转换成二进制文件。

other computer converts binary into file.

不过，我似乎无法找到一种方法将文件转换为二进制。我找到了一种方法来转换一个字符串中使用

However, I can't seem to find a way to convert a file to binary. I found a way to convert a string to binary using

public static string StringToBinary(string data)
{
    StringBuilder sb = new StringBuilder();
    foreach (char c in data.ToCharArray())
    {
        sb.Append(Convert.ToString(c, 2).PadLeft(8,'0'));
    }
    return sb.ToString();
}

从的 http://www.fluxbytes.com/csharp/convert-string-to-binary-and - 二进制到字符串在C / 。
，但我不能找出如何将文件转换为二进制文件（该文件可以是任何扩展）。

From http://www.fluxbytes.com/csharp/convert-string-to-binary-and-binary-to-string-in-c/ . But I can't find out how to convert a file to binary (the file could be of any extension).

所以，我怎么能转换文件为二进制？有没有更好的办法，我写我的程序？

So, how can I convert a file to binary? Is there a better way for me to write my program?

推荐答案

为什么你不只是以二进制方式打开文件？
此功能以二进制方式打开文件，并返回字节数组：

Why don't you just open the file in binary mode? this function opens the file in binary mode and returns the byte array:

private byte[] GetBinaryFile(filename)
{
     byte[] bytes;
     using (FileStream file = new FileStream(filename, FileMode.Open, FileAccess.Read))
     {
          bytes = new byte[file.Length];
          file.Read(bytes, 0, (int)file.Length);
     }
     return bytes;
}

然后将其转换为位：

then to convert it to bits:

byte[] bytes = GetBinaryFile("filename.bin");
BitArray bits = new BitArray(bytes);

现在位变量保存0,1你想要的。

now bits variable holds 0,1 you wanted.

或者你可以这样做：

private BitArray GetFileBits(filename)
{
     byte[] bytes;
     using (FileStream file = new FileStream(filename, FileMode.Open, FileAccess.Read))
     {
          bytes = new byte[file.Length];
          file.Read(bytes, 0, (int)file.Length);
     }
     return new BitArray(bytes);
}
