Byte to Binary String C# - Display all 8 digits
50,301
Solution 1
Convert.ToString(MyVeryOwnByte, 2).PadLeft(8, '0');
This will fill the empty space to the left with '0' for a total of 8 characters in the string
Solution 2
How you do it depends on how you want your output to look.
If you just want "00011011", use a function like this:
static string Pad(byte b)
{
return Convert.ToString(b, 2).PadLeft(8, '0');
}
If you want output like "00011011", use a function like this:
static string PadBold(byte b)
{
string bin = Convert.ToString(b, 2);
return new string('0', 8 - bin.Length) + "<b>" + bin + "</b>";
}
If you want output like "0001 1011", a function like this might be better:
static string PadNibble(byte b)
{
return Int32.Parse(Convert.ToString(b, 2)).ToString("0000 0000");
}
Solution 3
Pad the string with zeros. In this case it is PadLeft(length, characterToPadWith)
. Very useful extension methods. PadRight()
is another useful method.

I want to display one byte in textbox. Now I'm using:
Convert.ToString(MyVeryOwnByte, 2);
But when byte is has 0's at begining those 0's are being cut. Example:
MyVeryOwnByte = 00001110 // Texbox shows -> 1110 MyVeryOwnByte = 01010101 // Texbox shows -> 1010101 MyVeryOwnByte = 00000000 // Texbox shows -> <Empty> MyVeryOwnByte = 00000001 // Texbox shows -> 1
I want to display all 8 digits.

Gabe over 13 years@Jeff: I posted this version because sometimes the
new string()
technique is useful. You didn't question Gregory's mention ofPadRight
, and that function doesn't even solve the problem. -
Jeff Yates over 13 yearsHow I reacted to someone else's response is entirely irrelevant. I just thought it strange to see you downplay your answer by referring to a better solution that you didn't give and that the suggestion you had was not particular easy to read. As SO is a resource for getting a good answer, you'd be better including the PadLeft solution entirely AND your alternative - you might well be the better answer then. This isn't about first, it's about best.

PadRight
is a useful method but not in this scenario. I recommend you remove that from your answer (or add every other useful .NET method - I know which I'd pick :D). -
Gabe over 13 yearsAlso, they're not extension methods.

Gabe over 13 years@Jeff: I prefer a separate post for each answer so that one can easily browse answers without having to wade through duplicates. However, I have made an exception today, and just for you have put 3 answers into a single post.

THBBFT over 9 yearsThe third answer was almost approximately what I was looking for. The pattern I needed was 00 00 00 00 ... i think i figured it out :)
