String Char and Bitstrings Conversion Help

[tortuous801]

Hello
I am having trouble figuring out how to take a string input and ultimately convert each letter of the string into binary then print out the binary results then convert from binary back to a string. I have searched on how to convert from string to bitstring but have not been successful.

Can anyone give me a hand here?

Thanks

Check whether the following idea works.

1)Read every character
2)Get the ASCII value of it.
3)get the binary value for the ASCII value
4)print it
5)Do the reverse to convert the binary to string

One thing you should take acre is always ensure that every binary number is of caertain number of bits in it that is 16 bits or 32 bits

Sorry - this should be in .NET forum ...

I had the same problem in recalling a MD-5 hashed password field that is binary(16) in the database. Unless I was resetting the password, I needed to write the original back to the database. Here is what I created:

    ''' <summary>
    ''' Function to convert binary data to it's hexadecimal string representation.
    ''' Useful for saving binary database values as a string.
    ''' </summary>
    ''' <param name="ByteVal">A byte array</param>
    ''' <returns>String - 2 character for every byte, i.e. byte(0)= decimal 80 returns hex 50</returns>
    Public Shared Function BinaryToString(ByVal ByteVal As Byte()) As String
        Dim sValue As String = ""
        Dim xElement As Integer
        For xElement = 0 To (UBound(ByteVal))
            sValue = sValue & Right("00" & Convert.ToString(ByteVal(xElement), 16).ToUpper(), 2) 
          '  hexadecimal is base 16, parameter of Convert function
        Next
        Return sValue
    End Function

            sOut = StringVal.Substring((X * 2), 2)
            dbyte = Convert.ToByte(sOut, 16)
            DataBytes(X) = dbyte
        Next
        Return DataBytes
    End Function

Moving this to the .NET forum.

Now, by "binary data" do you mean their ascii values?
With the ASCII encoding, you can just go from char to byte.

string mystr="Alan is going far.";
char c = mystr[0];
int cval= (int)c;
byte bval = (byte)c;
//cval now = 65, which is the ascii value
//bval also now = 65
