C# Convert.ToInt32(object) Method

Convert.ToInt32(object) Method is used to convert a specific object’s value to its equivalent 32-bits signed integer (int32).

Note: Value of the object to be converted should not exceed the range of a signed 32-bit integer i.e. the converted value through the function should match the range of a signed integer of 32-bit.

Syntax:

    int Convert.ToInt32(object value);

It accepts an object value/variable as an argument and returns its equivalent signed integer.

Example:

    Input: 
    object a = 'A';
    Output:
    65

    Input: 
    object a = 10.23m;
    Output:
    10

Code:

using System;
using System.Text;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            object a = 'A'; //char object
            object b = 10.23f; //single/float objet
            object c = 10.23m; //decimal object
            
            Console.WriteLine("value of a: {0}, type of a: {1}", a, a.GetType());
            Console.WriteLine("value of b: {0}, type of b: {1}", b, b.GetType());
            Console.WriteLine("value of c: {0}, type of c: {1}", c, c.GetType());

            //converting to Int32 & printing values & types
            Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(a), Convert.ToInt32(a).GetType());
            Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(b), Convert.ToInt32(b).GetType());
            Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(c), Convert.ToInt32(c).GetType());

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output

value of a: A, type of a: System.Char
value of b: 10.23, type of b: System.Single
value of c: 10.23, type of c: System.Decimal
value: 65, type: System.Int32
value: 10, type: System.Int32
value: 10, type: System.Int32
