I have got a data(payload) of about 200 bits + so how can I manipulate this code to get the conversion. Please help me out , its urgent !! NoMee ALy

I used a 8 bit binary string for the character "j" and copy and pased it into the text box many times (seperated by the space to allow the split), possibly as much as 200 times, and the code converted it fine each time. Can you be more specific with the exception that is thrown?

Here's a snippet I wrote that converts ASCII to it's binary form, this may help you solve your issues:

csharp


public string ToBinary(string str)
{
    string converted = string.Empty;
    byte[] byteArray = GetByteArray(str);

   //create a memory stream
    MemoryStream stream = new MemoryStream();

    //create BinaryWriter based on our MemoryStream
    BinaryWriter writer = new BinaryWriter(stream);
    
    try
    {
        //write out in binary
        writer.Write(byteArray);
    }
    catch (Exception ex)
    {
        return ex.Message;
    }

    //now we get to start the conversion: Loop through each
    //byte in the byte array
    for (int i = 0; i < byteArray.Length; i++)
    {
        for (int j = 0; j < 8; j++)
        {
            converted += (byteArray[i] & 0x80) > 0 ? "1" : "0";
            byteArray[i] <<= 1;
        }
    }

    return converted;
}

I have got a 200 bits binary data and want to convert each 16 bits into one ASCII character. I want to breakdown the total bits into 16bits tag like this ! 200 bits 16bits--16 bits-- 16 bits-- 16 bits and so on Please help me out !
