C# modbus RTU 中使用到的 ushort[] 转 int 与 int 转 ushort[]

public static int ushorts2int(ushort[] res)
{
int high = res[0];
int low = res[1];
int value = (high << 16) + low;
return value;
}

public static ushort[] int2ushorts(int res)
{
ushort ust1 = (ushort)(res >> 16);
ushort ust2 = (ushort)res;
return new ushort[] { ust1, ust2 };
}
