The int version of the TryParse() methods converts string data to an int. The first argument is the string that you want to convert, and the second argument is an out parameter that receives the result if the conversion is successful, or 0 if it is not. The method returns a Boolean value that indicates whether the conversion was successful. Write this method using exception handling techniques to ensure that the method returns correctly whether or not the conversion is successful. Use the method Convert.ToInt32(inputString)to do the conversion.

Question

What will be an ideal response?

Answer 1

The method should be similar to the following example:
public static bool TryParse(string inputString, out int number)
{
bool wasSuccessful = true;
try
{
number = Convert.ToInt32(inputString);
}
catch(FormatException e)
{
wasSuccessful = false;
number = 0;
}
return wasSuccessful;
}
