I want to take a string from a textbox (txtFrom) and save the first word and save whatever is left in another part. (the whatever is left is everything past the first space)
Use String.Split(Char[], Int32) overload like this:
String.Split(Char[], Int32)
string[] array = txtFrom.Text.Split(new char[]{' '},2);
