Convert to decimal from array

I have an array as such:

int[] fourbits = new int[4];
fourbits[0] = neuroninputs.input1;
fourbits[1] = neuroninputs.input2;
fourbits[2] = neuroninputs.input3;
fourbits[3] = neuroninputs.input4;

Each element contains a binary value. For example :

Console.WriteLine(fourbits[0]);

outputs 1.

What I am trying to do is to take every value from this array(1010) and convert this to decimal and print this value(10).

First concatenate all the bits into a string using String.Join,then use Convert.ToInt32 method specifying the base parameter.:

var value = Convert.ToInt32(string.Join("", fourbits), 2);

Console.WriteLine(value);

Note: You need to make sure that your array contains only ones and zeros in order to speficy base parameter as 2. Otherwise you will get a FormatException.
