I have this in hex: 08 Which is this in binary: 0000 1000 (bit positions: 7,6,5,4,3,2,1,0)

Now I would like to make a bitmask in C# , so I have bit position 3. Here in example 1 or better (the one in ""): 0000 "1"000

How to show only bit3 in TextBox.text

Thanks Mano.

Does this answer your question? [Using a bitmask in C#](https://stackoverflow.com/questions/3261451/using-a-bitmask-in-c-sharp) – Arphile Jul 13 '20 at 07:42

`int bit3 = (source >> 3) & 1;` you'll get either `0` or `1` – Dmitry Bychenko Jul 13 '20 at 07:45
Could you provide some examples, please? Suppose you have, say, `source == 1234`; what `TextBox3.Text` should have then? – Dmitry Bychenko Jul 13 '20 at 07:57
txtData.Text = Convert.ToString(data, 2).PadLeft(8, '0' ); – Mano Jul 13 '20 at 08:59
now i used txtData.Text = Convert.ToString(data, 2).PadLeft(8, '0' ); the output show "0000 1000" , I need to show only bit 3 . Please advise. – Mano Jul 13 '20 at 09:00
I would create an enumeration so the string name of the bit can be shown in the textbox. – jdweng Jul 13 '20 at 09:54
