How to read inputs as integers in C#?
To read inputs as integers in C#, use the Convert.ToInt32() method.
res = Convert.ToInt32(val);
Let us see how −
The Convert.ToInt32 converts the specified string representation of a number to an equivalent 32-bit signed integer.
Firstly, read the console input −
string val; val = Console.ReadLine();
After reading, convert it to an integer.
int res; res = Convert.ToInt32(val);
Let us see an example −
Example
using System;
using System.Collections.Generic;
class Demo {
static void Main() {
string val;
int res;
Console.WriteLine("Input from user: ");
val = Console.ReadLine();
// convert to integer
res = Convert.ToInt32(val);
// display the line
Console.WriteLine("Input = {0}", res);
}
}Output
Input from user: Input = 0
The following is the output. The input is entered by the user.
Input from user: 2 Input = 2
