How to use console.readline() in c

#This method is used to read the next line of characters from the standard input stream. It's under the Console class (system namespace). If the standard input device is a keyboard, the ReadLine method blocks until the user presses the Enter key. And, if standard input is redirected to a file, this method will read a line of text from the file.

Usage: public static string ReadLine ();

Return value: It returns the next line of characters of string type from the input stream; if there is no more If multiple rows are available, null is returned.

Exception:

IOException: If an I/O error occurs.

OutOfMemoryException: If there is not enough memory to allocate a buffer for the returned string.

ArgumentOutOfRangeException: If the number of characters in the next line of characters is greater than MaxValue.

The following example program is intended to illustrate the use of the above method:

Example 1: Here, the user is asked to enter. Since age is an integer, we performed the type conversion using the Convert.ToInt32() method. It reads the next line from the input stream. It blocks until the enter key is pressed. Therefore, it is often used to pause the console so that the user can inspect the output.

// C# program to illustrate 
// the use of Console.ReadLine() 
using System; 
using System.IO; 
  
class GFG { 
      
    // Main Method 
    public static void Main() 
    { 
        int age; 
        string name; 
  
        Console.WriteLine("Enter your name: "); 
          
        // using the method 
        // typecasting not needed  
        // as ReadLine returns string 
        name = Console.ReadLine(); 
          
        Console.WriteLine("Enter your age: "); 
          
        // Converted string to int 
        age = Convert.ToInt32(Console.ReadLine()); 
          
        if (age >= 18)  
        { 
            Console.WriteLine("Hello " + name + "!"
                        + " You can vote"); 
        } 
        else { 
            Console.WriteLine("Hello " + name + "!"
                + " Sorry you can't vote"); 
        } 
    }  
}
