string binValue = Convert.ToString(64, 2);

But I need to show all 8 digits.

So

  string binValue = Convert.ToString(6, 2);

which would normally be "110" would need to be shown as:

00000110


How?

Thanks!!!  :)

           var binStr = Convert.ToString(2, 2);
            
            var sb = new StringBuilder();
            for(int i=0;i<8-binStr.Length;i++)
            {
                sb.Append("0");
            }

            sb.Append(binStr);

... is what I ended up doing as well.

Thanks,

Q:  .NET does not provide a cleaner way to do this?

Something like, "I am representing this value as an 8-bit binary.  I want each digit to be represented, even if it is OFF (1 would be "00000001", 64 would be "10000000")"

Without having to "brute force" pad the difference with "0"?

well this is default behaviour, any leading zeros are ripped off....
