c#中的字符串到二进制

本文关键字：二进制 字符串 | 更新日期: 2023-09-27 17:50:05

我有一个将字符串转换为十六进制的函数，如下所示，

public static string ConvertToHex(string asciiString)
{
    string hex = "";
    foreach (char c in asciiString)
    {
         int tmp = c;
         hex += String.Format("{0:x2}", (uint)System.Convert.ToUInt32(tmp.ToString()));
    }
    return hex;
}

你能帮我在我的示例函数的基础上再写一个字符串到二进制函数吗?

public static string ConvertToBin(string asciiString)
{
    string bin = "";
    foreach (char c in asciiString)
    {
        int tmp = c;
        bin += String.Format("{0:x2}", (uint)System.Convert.????(tmp.ToString()));
    }
    return bin;
}

c#中的字符串到二进制

给你:

public static byte[] ConvertToByteArray(string str, Encoding encoding)
{
    return encoding.GetBytes(str);
}
public static String ToBinary(Byte[] data)
{
    return string.Join(" ", data.Select(byt => Convert.ToString(byt, 2).PadLeft(8, '0')));
}
// Use any sort of encoding you like. 
var binaryString = ToBinary(ConvertToByteArray("Welcome, World!", Encoding.ASCII));

听起来你基本上想要一个ASCII字符串，或者更理想的是一个字节[](因为你可以用你喜欢的编码模式将你的字符串编码为字节[])变成一个1和0的字符串?即101010010010100100100101001010010100101001010010101000010111101101010

这将为您做…

//Formats a byte[] into a binary string (010010010010100101010)
public string Format(byte[] data)
{
    //storage for the resulting string
    string result = string.Empty;
    //iterate through the byte[]
    foreach(byte value in data)
    {
        //storage for the individual byte
        string binarybyte = Convert.ToString(value, 2);
        //if the binarybyte is not 8 characters long, its not a proper result
        while(binarybyte.Length < 8)
        {
            //prepend the value with a 0
            binarybyte = "0" + binarybyte;
        }
        //append the binarybyte to the result
        result += binarybyte;
    }
    //return the result
    return result;
}

这是一个扩展函数:

        public static string ToBinary(this string data, bool formatBits = false)
        {
            char[] buffer = new char[(((data.Length * 8) + (formatBits ? (data.Length - 1) : 0)))];
            int index = 0;
            for (int i = 0; i < data.Length; i++)
            {
                string binary = Convert.ToString(data[i], 2).PadLeft(8, '0');
                for (int j = 0; j < 8; j++)
                {
                    buffer[index] = binary[j];
                    index++;
                }
                if (formatBits && i < (data.Length - 1))
                {
                    buffer[index] = ' ';
                    index++;
                }
            }
            return new string(buffer);
        }

你可以这样使用:

Console.WriteLine("Testing".ToBinary());

，如果您添加'true'作为参数，它将自动分隔每个二进制序列。

下面将为您提供每个字符的低字节的十六进制编码，这看起来像您所要求的:

StringBuilder sb = new StringBuilder();
foreach (char c in asciiString)
{
    uint i = (uint)c;
    sb.AppendFormat("{0:X2}", (i & 0xff));
}
return sb.ToString();
