please what the following statements mean??

[sara ali alali]

foreach (char c in textBox1.Text)
bits += Convert.ToStrin g((int)c,2).Pad Left(8, '0');

[Christian Binder]

It means: take every character of the Text in the TextBox (foreach(char c in textBox1.Text)), take the integer-keycode ((int)c) of this character, convert it to binary string (Convert.ToStrin g((int)c,2)), if this string is short than 8 digits, fill them up with 0's (...PadLeft(8,'0 ')) and append it to a string-variable called bits

References: Convert.ToStrin g()
String.PadLeft( )
