将布尔数组转换为字节 [英] Converting Boolean array into byte

问题描述

大家好！

作为初学者，我不熟悉.NET将类型转换为其他类型的方法，因此，我恳请以下问题提供帮助.

我使用了一种将消息接收为8个字节长字节数组的设备.其字节之一表示输出状态.我已经制作了.NET类和UI来控制这些状态.唯一的问题是无法将我的布尔数组转换为Byte..

这是一个示例:

Hi all!

As beginner programmer Im not familiar with .NET methods to convert types to another so I kindly ask help with following problem.

I have empedded device which recieves messages as 8 bytes long byte array. One of its bytes represents output states. I have made .NET class and UI to control those states. Only problem is that cant cast my bool array into Byte..

Here is an example:

bool[] StatesArray = { false, true, true, false, false, false, false , false}; // States comes from MyClass properties changed by Ui component (eg. CheckBox)

//target device will read states as binary form eg. above state array: 01100000

byte[] Message = new byte[8]; //Byte array which will be The Message to be send (one index includes our states as Byte)

byte States; // byte which represents states 

//States = ???? // Problem! Convert StatesArray to one byte

//Message[4] = States; //Add our states into our message

//Send the message etc..

希望你有主意:)

干杯！

Hope you got idea :)

Cheers!

推荐答案

例如:

byte encodebool(bool[] arr)
{
  byte val = 0;
  foreach (bool b in arr)
  {
    val <<= 1;
    if (b) val |= 1;
  }
  return val;
 }

您是否考虑了枚举，而不是使用布尔数组:

Rather than using an array of bools, have you considered an enum:

public enum StatusByte : byte
    {
    Ready = 0,
    Abort = 1,
    TxReady = 2,
    RxReady = 3,
    TxError = 4,
    RxError = 5,
    }
private void button1_Click(object sender, EventArgs e)
    {
    StatusByte sb = ReadStatus();
    if ((int) (sb & StatusByte.Ready) == 1)
        {
        }
    }

bool[] StatesArray = { false, true, true, false, false, false, false , false}; 
BitArray bits = new BitArray(StatesArray);
byte[] Bytes = new byte[1];
bits.CopyTo(Bytes, 0);
//Bytes[0] is your answer
