C# 实现16进制字符串转换ASCII

现成代码，直接调用

//方法里直接传入需要转换的16进制字符串
String ReceiveCmd=HexStringToASCII(SerialCom.ByteToString(serialCom.ReceiveAllData())); 

 		/// <summary>
        /// 将一条十六进制字符串转换为ASCII
        /// </summary>
        /// <param name="hexstring">一条十六进制字符串</param>
        /// <returns>返回一条ASCII码</returns>
        public static string HexStringToASCII(string hexstring)
        {
   
            byte[] bt = HexStringToBinary(hexstring);
