Hi All,

Battling away I need to display a binary from a string "4020",
I have used the method
```MessageBox.Show(Returned);
Hexvalue2 = Convert.ToUInt32(Returned, 16);
MessageBox.Show(Hexvalue2.ToString());
```
to convert my string to a form that can be used that with
```if ((Hexvalue2 & 0x0001) == 0)
{
//MessageBox.Show("hello bit 1 not set");
checkBox1.Checked = false;
label9.Text = "False";
}
else
{
// MessageBox.Show("bit 1 set");
checkBox1.Checked = true;
label9.Text = "True";

}
```
to check if bits are set and update a string accordingly This appears to working fine but bits 4 & 32 seem to inverted I was hoping for a look at the binary data before yelling fowl to higher ups! So I did the following
```Hexvalue2 = Convert.ToUInt32(IU_status,2);
textBox2.Text = Hexvalue2.ToString();
```
and get an Could not find any recognizable digits error. Is the correct way of doing what I'm after or have I been seduced by Convert.To again?

## Solution 1

You are taking an input from the TextBox and wanted to convert it into binary or hexadecimal number.

Since you take input from the TextBox you have its datatype is String and you have to convert that String into int, long, etc Depending upon your requirement.

bcoz when you convert string to any numerical form like int, long, float, etc it is in the decimal number only

To convert your Number to any Base like Binary, octal, etc refer to Conversion of Decimal to any Base (Binary, Octal or Hexa) and vice-versa (C#)[^]

Didn't need to do it in the end
