Question

我想将文本转换为二进制文件，然后尝试将二进制文件转换为字符串文本。如果tobin已经是字符串，我如何将private void iTalk_Button_12_Click(object sender, EventArgs e) { ambiance_RichTextBox2.Text = tobin(ambiance_RichTextBox1.Text); } public string tobin(string inp) { StringBuilder sb = new StringBuilder(); foreach (char L in inp.ToCharArray()) { sb.Append(Convert.ToString(L, 2).PadLeft(8, '0')); } return sb.ToString(); }转换回文本？

Answer 1

        private void iTalk_Button_12_Click(object sender, EventArgs e)
        {
            ambiance_RichTextBox2.Text = BinaryToString(ambiance_RichTextBox1.Text);
           //use what u need: BinaryToString or StringToBinary.
        }

将字符串转换为二进制：

        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();
        }

将二进制转换为字符串：

        public static string BinaryToString(string data)
        {
            List<Byte> byteList = new List<Byte>();

            for (int i = 0; i < data.Length; i += 8)
            {
                byteList.Add(Convert.ToByte(data.Substring(i, 8), 2));
            }

            return Encoding.ASCII.GetString(byteList.ToArray());
        }

祝你好运！

你可以这样使用，

public static string BinaryToString(string data)
{
List<Byte> byteList = new List<Byte>();

for (int i = 0; i < data.Length; i += 8)
{
 byteList.Add(Convert.ToByte(data.Substring(i, 8), 2));
}

return Encoding.ASCII.GetString(byteList.ToArray());
}

将字符串转换为二进制

string s = "hai"; 

byte []arr = System.Text.Encoding.ASCII.GetBytes(s);

将二进制转换为字符串

byte[] arr ;

string s =  Encoding.ASCII.GetString(arr);

目前，您正在将char（可以表示为数字）转换为其二进制表示形式（此数字是ASCII数字）。但是如果要将字符串转换为二进制，则应使用编码。编码确定文本如何转换为二进制文件。

例如：

static void Main(string[] args)
{
    string input = "This is an example text.";

    Console.WriteLine(input);
    string asBin = ToBinary(input);
    Console.WriteLine(asBin);
    string asText = ToText(asBin);
    Console.WriteLine(asText);
}

static string ToBinary(string input, System.Text.Encoding encoding = null)
{
    if (encoding == null)
        encoding = System.Text.Encoding.UTF8;

    var builder = new System.Text.StringBuilder();
    var bytes = encoding.GetBytes(input); // Convert the text to bytes using the encoding

    foreach (var b in bytes)
        builder.Append(Convert.ToString(b, 2).PadLeft(8, '0')); //Convert the byte to its binary representation

    return builder.ToString();
}

static string ToText(string bytes, System.Text.Encoding encoding = null)
{
    if (encoding == null)
        encoding = System.Text.Encoding.UTF8;

    var byteCount = 8;
    var byteArray = new byte[bytes.Length / 8]; // An array for the bytes
    for (int i = 0; i < bytes.Length / byteCount; i++)
    {
        var subBytes = bytes.Substring(i * byteCount, byteCount); // Get a subpart of 8 bits
        var b = Convert.ToByte(subBytes.TrimStart('0'), 2); // Convert the subpart to a byte
        byteArray[i] = b; // Add the byte to the array
    }

    return encoding.GetString(byteArray); // Convert the array to text using the right encoding.
}

现在，如果您想使用ASCII编码，可以按如下方式调用函数：

Console.WriteLine(input);
string asBin = ToBinary(input, System.Text.Encoding.ASCII);
Console.WriteLine(asBin);
string asText = ToText(asBin, System.Text.Encoding.ASCII);
Console.WriteLine(asText);
