Please help what I am doing wrong.

Answer 1

you are doing wrong on this line

msg2 = input.Substring(msg1.Length, size);

what you are doing here is, creating a substring msg2 that is longer then the size of your first string msg1,

here, your msg1.Length equals 30 and your size equals 58 means that you are trying to create a string having startingIndex = 30 and Length = 58 and this will be impossible in this condition, because the Length of your second string msg1 is 30 and it is less then Size i.e. 58.

Albin Sunnanbo answer is good as per your requirement.i.e.

msg2 = input.Substring(msg1.Length, size - msg1.Length);
