I am trying to convert a boolean array to a byte

Question

I am having trouble with last 2 lines of the code. I am trying to convert a boolean array with 8 values to a byte. I am also trying to write the converted byte to the output file.

Hello, program code inside attachment is full of errors. Look at the part of code below and notice that while loop has no end, variable bytes never changes its value to zero !? int bytes = 1; while (bytes > 0) { for ( int i = 0; i { if (tif == true ) { tif = false ; } else if (tif == false ) { tif = true ; } array[i] = tif; if (i == 7) { val = Convert.ToByte(array); //Unable to cast object of type 'System.Boolean[]' to type 'System.IConvertible' } } output.Write(buffer, 0, bytes); // I WANT TO WRITE "VAL" TO OUTPUT FILE. } All the best, Željko Peric

Hi Tom The example is pretty simple. The code is looping through the Bool array and setting the bit at "true" position. I think you might get confused with "|=" operator. This is performing Bitwise logical OR operation. refer https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/or-assignment-operator

I looked at that example and it was very confusing to understand.
