How to remove first 10 characters from a string?

Question

How to ignore the first 10 characters of a string?

Input:

str = "hello world!"; 

Output:

d! 

Answer 1

str = str.Remove(0,10); Removes the first 10 characters

or

str = str.Substring(10); Creates a substring starting at the 11th character to the end of the string.

For your purposes they should work identically.

Answer 2

str = "hello world!"; str.Substring(10, str.Length-10) 

you will need to perform the length checks else this would throw an error
