推荐答案

将您的文本文件加载到单个字符串中，然后调用此方法:

Load your text file into a single string, and then call this method:

//--------------------------------------------------------------------------------
public static byte[] StringToByteArray(string text)
{
    UTF8Encoding encoding = new UTF8Encoding();
    return encoding.GetBytes(text);
}

要将其放回字符串中，请调用此方法:

To put it back into a string, call this method:

//--------------------------------------------------------------------------------
public static string ByteArrayToString(byte[] array)
{
    UTF8Encoding encoding = new UTF8Encoding();
    string text  = encoding.GetString(array);
    return text;
}

public bool writeByteArrayToFile(byte[] buff, string fileName)
{
bool response = false;

try
{
FileStream fs = new FileStream(fileName, FileMode.Create, FileAccess.ReadWrite);
BinaryWriter bw = new BinaryWriter(fs);
bw.Write(buff);
bw.Close(); //Thanks Karlo for pointing out!
response = true;
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}

return response;
}
