how to convert string to byte array in C#

how to convert the string to byte array.
i have string with content as "Edaboard"
and i want that string in SerialDataBuffer[] array. so to convert this string in the byte array form.

try

string data = "EDAboard";
 byte[] SerialDataBuffer = Encoding.ASCII.GetBytes(data);

is this byte array i can send over USB now?

- - - Updated - - -

Recently i tried this one

string data = "EDAboard";
 byte[] SerialDataBuffer = Encoding.ASCII.UTF8.GetBytes(data);

but this is not work....

what happens?

you need to copy the serialDataBuffer to the USB outbuffer, e.g. something like

OUTBuffer[0] = 0x00;	//The first byte is the "Report ID" and does not get sent over the USB bus.  Always set = 0.
OUTBuffer[1] = 0x37;	//READ_POT command (see the firmware source code), gets 10-bit ADC Value
 for (uint i = 2; i < 65; i++)
     OUTBuffer[i] = SeralDataBuffer[i-2];
if (WriteFile(WriteHandleToUSBDevice, OUTBuffer, 65, ref BytesWritten, IntPtr.Zero))	//Blocking function, unless an "overlapped" structure is used

the first byte is not sent, the second is a command to the target (in this case READ_POT) the rest is data to send

Using UTF8 conversion

byte[] bArray = Encoding.UTF8.GetBytes (inputString);

Using ASCII conversion

byte[] bArray = Encoding.ASCII.GetBytes (inputString);

now if i entered string in textbox then how to get it in array?
.

something along the lines of

private void textBox1_TextChanged(object sender, EventArgs e)
{
  byte[] bArray = Encoding.ASCII.GetBytes(textBox1.Text);
}

i tried this one also but not doing anything.
Other things working good like send string after clicking one button abd reading ADC.
But only this task giving problem.

can you print out the array contents to the console to check what is happening, e.g.

           byte[] bArray = Encoding.ASCII.GetBytes(textBox1.Text);
            for (int i=0; i < bArray.Length; i++)
                Console.WriteLine(" {0}", bArray[i]);

it should print the ASCII code of the characters, e.g. abc gives 97 98 99
