Int32.Parse(String) Method in C# with Examples Last Updated : 12 Jun, 2019 Comments Improve Suggest changes Like Article Like Report Int32.Parse(String) Method is used to convert the string representation of a number to its 32-bit signed integer equivalent. Syntax: public static int Parse (string str); Here, str is a string that contains a number to convert. The format of str will be [optional white space][optional sign]digits[optional white space]. Return Value: It is a 32-bit signed integer equivalent to the number contained in str. Exceptions: ArgumentNullException: If str is null. FormatException: If str is not in the correct format. OverflowException: If str represents a number less than MinValue or greater than MaxValue. Below programs illustrate the use of above-discussed method: Example 1: csharp // C# program to demonstrate // Int32.Parse(String) Method using System; class GFG { // Main Method public static void Main() { // passing different values // to the method to check checkParse("2147483647"); checkParse("214,7483,647"); checkParse("-2147483"); checkParse(" 2183647 "); } // Defining checkParse method public static void checkParse(string input) { try { // declaring Int32 variable int val; // getting parsed value val = Int32.Parse(input); Console.WriteLine("'{0}' parsed as {1}", input, val); } catch (FormatException) { Console.WriteLine("Can't Parsed '{0}'", input); } } } Output: '2147483647' parsed as 2147483647 Can't Parsed '214,7483,647' '-2147483' parsed as -2147483 ' 2183647 ' parsed as 2183647 Example 2: For ArgumentNullException csharp // C# program to demonstrate // Int32.Parse(String) Method // for ArgumentNullException using System; class GFG { // Main Method public static void Main() { try { // passing null value as a input checkParse(null); } catch (ArgumentNullException e) { Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } catch (FormatException e) { Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } } // Defining checkparse method public static void checkParse(string input) { // declaring Int32 variable int val; // getting parsed value val = Int32.Parse(input); Console.WriteLine("'{0}' parsed as {1}", input, val); } } Output: Exception Thrown: System.ArgumentNullException Reference: https://docs.microsoft.com/en-us/dotnet/api/system.int32.parse?view=netframework-4.7.2#System_Int32_Parse_System_String_ Comment More infoAdvertise with us Next Article Int32.Parse(String) Method in C# with Examples K Kirti_Mangal Follow Improve Article Tags : C# CSharp-method CSharp-Int32-Struct Similar Reads Int16.Parse(String) Method in C# with Examples Int16.Parse(String) Method is used to convert the string representation of a number to its 16-bit signed integer equivalent.
