in Substring you can pass only one parameter or 2parameter ,
in Substring With one parameter is: int index , its mean you have to pass the start number(that zero base value) of the string for new string and its an integer parameter .
Substring with two parameter have index and int length , that is the length of your new string!
you pass a index that is more than the string legth so this error is obvious , you have to change the index!

Solution 1

You are trying to do a SubString wherever the length of the substring you are trying to retrieve is larger than the string itself.
For more information, read about the Substring method here[^].
