how to convert bool array to char variable?

Question

I have a boolean array which holds some values that represent ASCII value:

bool[] myBoolReceived = new bool[8];

I try to convert it to a char so I can add it to a list that holds chars.

myReceivedMessage = new List<char>();

I tried to use Convert.ToChar method but it not seems to work.

A bool can hold two values: true and false. I am not sure what exactly you are trying to say by "convert bool array to char avariable". Can you please clarify that? — Emz

@Emz That part seems reasonably clear to me: the 8 bits of an 8-bit integer value are stored as separate elements of an array. There are a lot of things that aren't clear to me (such as why not simply use byte, why use 8 bits when ASCII is a 7-bit character set, which order the bits are in) that make the question hard to answer, though. — user743382

@Emz He probably means that the bool array represents bits in a byte. — cbr

I mean that if for example I have : false, true , true ,true, true, false, false,true it holds y character — axcelenator

@hvd, sticksandstones.kstrom.com/appen.html Here it stands for 8 bit — axcelenator

char contains 2 bytes. you can convert bool array to a byte and then convert it to a character using Convert class.

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