How to convert a char to binary?

hello!

I have a char called 'ch',
how can I get it's binary value?

thanks

:wave:

Here is a link to a short program to do this type of thing..

It's in VB.NET, but since you know VB 6, there shouldn't be any problems in easily converting it.

If you mean you want its ASCII or Unicode value then use:

Code:

---

int charCode = Convert.ToInt32(ch);

---

If you want to see the binary representation of the integer then you would use:

Code:

---

string binaryCharCode = Convert.ToString(charCode, 2)

---

If you mean something else then it's not clear to me.

Wouldn't the binary representation be base 2 rather than 16 which is Hex?

string binaryCharCode = Convert.ToString(charCode, 2)

I'm sure I don't know what you're talking about. The base IS 2 in my code and always was, no matter what anyone says. :blush: :D

You dont know the difference between a char and int? I hope you do now!

I encountered the same Issue. I parse a binary as an integer for a script interpreter. when i do a binary negation

i get the 2's complement but with 32 bit because its an integer? how can i convert the integer to a char in base2?

Because i cant edit my post - dont know why - here is what i do

Code:

---

int intValue = Convert.ToInt32(strToken, 2);
listTokens.Add(new Token(TokenType.Integer, intValue, m_iSourceLine, m_iSourceChar, strSourceLine));

No, over the course of my Computer Science degree and my 20 years as a professional developer I have never really encountered such an advanced concept. I'm sure one such as yourself could enlighten me though. I feel that I have a lot to learn from you. :rolleyes:

Hello, @dekelc

Please try this code,To convert char to binary:

Input Data : StringToBinary("fluxbytes.com")

Code:

---

public static string StringToBinary(string data)
{
    StringBuilder sb = new StringBuilder();
 
    foreach (char c in data.ToCharArray())
    {
        sb.Append(Convert.ToString(c, 2).PadLeft(8, '0'));
    }
    return sb.ToString();
}

I hope above code will be useful for you.

Thank you.
