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. Syntax:

public static short 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 16-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
// Int16.Parse(String) Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {

        // passing different values
        // to the method to check
        checkParse("14321");
        checkParse("15,784");
        checkParse("-4589");
        checkParse(" 456");
    }

    // Defining checkParse method
    public static void checkParse(string input)
    {

        try {

            // declaring Int16 variable
            short val;

            // getting parsed value
            val = Int16.Parse(input);
            Console.WriteLine("'{0}' parsed as {1}", input, val);
        }

        catch (FormatException) 
        {
            Console.WriteLine("Can't Parsed '{0}'", input);
        }
    }
}

Output:

'14321' parsed as 14321
Can't Parsed '15,784'
'-4589' parsed as -4589
' 456' parsed as 456

Example 2: For ArgumentNullException

csharp

// C# program to demonstrate
// Int16.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 Int16 variable
        short val;

        // getting parsed value
        val = Int16.Parse(input);
        Console.WriteLine("'{0}' parsed as {1}", input, val);
    }
}

Output:

Exception Thrown: System.ArgumentNullException
