//第一種方法:
            short D0 = 0;
            short D1 = 16320;
            byte[] L = System.BitConverter.GetBytes(D0);
            byte[] H = System.BitConverter.GetBytes(D1);          
            byte[] f = new byte[H.Length + L.Length];
            Buffer.BlockCopy(L, 0, f, 0, L.Length);
            Buffer.BlockCopy(H, 0, f, L.Length, H.Length);
            float FF = BitConverter.ToSingle(f, 0);
           textBox1.Text  = "結(jié)果應(yīng)該是:" + FF.ToString();
    //第二種方法:
            int HH=0;
            short D0 = 0;
            short D1 = 16320;
            HH |= (D1 & 0x0000ffff);
            HH = (HH << 16) | (D0 & 0x0000ffff);
            byte[] intBuff = BitConverter.GetBytes (HH);
            float FF = BitConverter.ToSingle(intBuff, 0);
            textBox1.Text = "結(jié)果應(yīng)該是:" + FF.ToString();
