二进制样式的字符串与byte数组互转函数示例

开发时用到的方法，记录下：

    /// <summary>
    /// 测试方法
    /// </summary>
    private void TestFun()
    {
        Response.Write("=================<p>");

        var b = BinaryStr2ByteArray("");
        var str = ByteArray2BinaryStr(b);
        str = str.TrimStart('');
        Response.Write(str);

        Response.Write("<p>=================");
        Response.End();
    }

    /// <summary>
    /// 二进制样式的字符串转byte数组
    /// </summary>
    /// <param name="binaryStr">二进制样式的字符串</param>
    /// <returns></returns>
    private byte[] BinaryStr2ByteArray(string binaryStr)
    {
        if (string.IsNullOrEmpty(binaryStr)) binaryStr = string.Empty;

        List<byte> byte_List = new List<byte>();
        var strL = binaryStr.Length;
        if (strL == )
            byte_List.Add();
        else if (strL >  && strL <= )
            byte_List.Add(Convert.ToByte(binaryStr, ));
        else
        {
            var tempStr = string.Empty;
            for (var i = strL; i > ; i = i - )
            {
                if (i -  > )
                    tempStr = binaryStr.Substring(i - , );
                else
                    tempStr = binaryStr.Substring(, i);
                byte_List.Add(Convert.ToByte(tempStr, ));
            }
        }

        byte_List.Reverse();
        return byte_List.ToArray();
    }

        else

            var tempStr = string.Empty;
            for (var i = ; i < bl; i++)
            {
                tempStr = Convert.ToString(byteArr[i], );
                if (tempStr.Length < )
                    tempStr = tempStr.PadLeft(, '');
