Getting Started

When working with data, you’ll likely need to convert string data into a numeric data type. The string data type can handle a non-numeric value, and it’s possible that performing a conversion from a string into a numeric data type will prompt a runtime error.

For example, the following code snippet:

In this scenario, a wrong value that cannot be converted into an int, given intentionally.

string name = “Bob”;
Console.WriteLine(int.Parse(name));
#Causes the following exception
#System.FormatException: ‘Input string was not in a correct format.’
