c# ASCII转成汉字

Question

asciic#

Answer 1

首先要转汉字你必须知道编码规则
然后将short型的数字分解成byte数组
调用对应的代码解码.

Answer 2

/// <summary>
/// 将ASCII码转换为字符
/// </summary>
/// <param name="asciiCode"></param>
/// <returns></returns>
public static string AscllToString(int asciiCode)
{
    if (asciiCode >= 0 && asciiCode <= 255)
    {
        ASCIIEncoding asciiEncoding = new System.Text.ASCIIEncoding();
        byte[] byteArray = new byte[] {(byte) asciiCode};
        string strCharacter = asciiEncoding.GetString(byteArray);
        return strCharacter;
    }
    else
    {
        throw new Exception("ASCII Code is not valid.");
    }
}

Answer 3

字母与ASCII码转换，供参考
private void btn_ToASCII_Click(object sender, EventArgs e)
        {
            if (txt_char.Text != string.Empty)//判断输入是否为空
            {
                if (Encoding.GetEncoding("unicode").//判断输入是否为字母
                    GetBytes(new char[] { txt_char.Text[0] })[1] == 0)
                {
                    txt_ASCII.Text = Encoding.GetEncoding(//得到字符的ASCII码值
                        "unicode").GetBytes(txt_char.Text)[0].ToString();
                }
                else
                {
                    txt_ASCII.Text = string.Empty;//输出空字符串
                    MessageBox.Show("请输入字母！","提示！");//提示用户信息
                }
            }
        }
        private void btn_ToChar_Click(object sender, EventArgs e)
        {
            if (txt_ASCII2.Text != string.Empty)//判断输入是否为空
            {
                int P_int_Num;//定义整型局部变量
                if (int.TryParse(//将输入的字符转换为数字
                    txt_ASCII2.Text, out P_int_Num))
                {
                    txt_Char2.Text =
                        ((char)P_int_Num).ToString();//将ASCII码转换为字符
                }
                else
                {
                    MessageBox.Show(//如果输入不符合要求弹出提示框
                        "请输入正确ASCII码值。", "错误！");
                }
            }
            string P_str_temp = "abc";
            string P_str = Encoding.GetEncoding("unicode").GetBytes(new char[] { P_str_temp[0] })[0].ToString();
        }
    }
