The Double.Parse approach will examine Just about every character during the string and build a numeric value based on the values of the characters in the string. If any of the characters are invalid, the Parse method fails (causing the Convert.Double strategy to fall short at the same time).

You are not aware of what will materialize to try this however , you're aware it could fall short (that's why IMO when a extra managed
