I am stuck with converting textbox string value to byte array. For ex;

Textbox1.text="ABC";
converting to byte array as
byte[] array1;
array1[0]=65;
array1[1]=66;
array1[2]=67;

Then I want to write all array1 to Textbox2 as

Textbox2=656667

Shortly, Input is "ABC" Ouput is "656667". I am working with below codes it gives error at

int value = Int32.Parse(arrText[i], System.Globalization.NumberStyles.Number);

sample code

string text = textBox1.Text + " ";// .Text + " ";
text.Trim();
string[] arrText = text.Split(' ');
byte[] data = new byte[arrText.Length];
for (int i = 0; i < arrText.Length; i++)
{
    if (arrText[i] != "")
    {
        int value = Int32.Parse(arrText[i],
            System.Globalization.NumberStyles.Number);  //gives error
        data[i] = (byte)Convert.ToByte(value);
    }
}

for (int i = 0; i < arrText.Length; i++)
{
    textBox2.Text += data[i].ToString();
}

Could you show me my error why it is happening? – user3722613 Sep 09 '14 at 12:35
What can I write in order to "int value = Int32.Parse(arrText[i], System.Globalization.NumberStyles.Number);" – user3722613 Sep 09 '14 at 12:38
What error are you getting? Have you run it in the debugger to see what the actual inputs are? Is `arrText[i]` a valid number? – D Stanley Sep 09 '14 at 12:39
What is the error you get ? – T00rk Sep 09 '14 at 12:40
I am getting "C# - System.FormatException: Input string was not in a correct format" My inputs 'A', "AB","1234" etc. – user3722613 Sep 09 '14 at 12:42
