如何把byte类型转换为string类型?

[sg163]

byte数组为:49,50,51,52,53,54
我想把这个转换为一个string变量,其实值就是:123456
请问如何转换?

            byte[] byteArray = new byte[] { 49,50,51,52,53,54};
            char[] ch = new char[byteArray.Length];
            for (int i = 0; i < byteArray.Length; i++)
            {
                ch[i] = (char)byteArray[i];
            }
            string str = new string(ch);

System.Text.Encoding.Default.GetString(byteArray);

string str = System.Text.Encoding.ASCII.GetString(byteArray);
