Which method would you use to convert a String to an Integer?

The choice that indicates both Convert.ToInt32() and Int.Parse() is correct, as both methods are commonly used in programming to convert a String representation of a number into an Integer.

Convert.ToInt32() is a method from the Convert class that converts various types into an Integer, including Strings. It's robust in handling values and is designed to return 0 for empty strings, which prevents potential errors during conversion when the input may not be guaranteed to be a valid number.

On the other hand, Int.Parse() is a method specifically designed to parse a string that contains a number. It attempts to convert the string directly into an Integer. However, if the string is in an invalid format or is null, it throws an exception, which means it requires more careful handling to ensure that the input is valid before using this method.

Both methods serve the purpose of converting a String to an Integer and can be used effectively depending on the circumstances and the validation needs of your application. This is why the correct answer encompasses both methods as valid means for conversion.
