Syntax to convert string formatted value to an integer: integer_variable = Convert.ToInt32(Console.ReadLine()); Program: /*C# program to input and print an integer number*/ using System; class ReadIntExample { static void Main() { //declare an integer variable int num = 0; //prompt message to take input Console.Write("Input an integer value: "); num = Convert.ToInt32(Console.ReadLine()); //print the value Console.WriteLine("num = " + num); } } Output Input an integer value: 200 num = 200 Program: using System; class ReadIntExample { static void Main() { try{ //declare an integer variable int num = 0; //prompt message to take input Console.Write("Input an integer value: "); num = Convert.ToInt32(Console.ReadLine()); //print the value Console.WriteLine("num = " + num); } catch(Exception ex){ Console.WriteLine("Error: " + ex.ToString()); } } } Output (when the input value is an integer) Input an integer value: 200 num = 200 Output (when input value is a string) Input an integer value: Hello Error: System.FormatException: Input string was not in the correct format at System.Int32.Parse (System.String s) [0x00000] in :0 at System.Convert.ToInt32 (System.String value) [0x00000] in :0 at ReadIntExample.Main () [0x00000] in :0
