I added a xmlfile in my solution.

I was trying the below program

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;


namespace ReadingXML
{
    class Program
    {
        static void Main(string[] args)
        {
     
            XmlReader reader = XmlReader.Create("~/ReadingXML/Countries.xml");
            while (reader.Read())
            {

                if ((reader.NodeType == XmlNodeType.Element) && (reader.Name == "State"))
                {
                    if (reader.HasAttributes)
                    {
                        Console.WriteLine(reader.GetAttribute("name"));

                    }

                }
                Console.ReadLine();


            }
        }
    }

This is not a valid file name. You cannot use "~". If you remove '~', it will mean the file path starting from the root directory on the current volume (bad idea, anyway). Moreover, there are no situations when using hard-coded file paths can be useful. Path names should always be calculated during runtime base on user input, some configuration files and/or environment.

For examples of such legitimate use of the application environment, please see my past answers:
How to find my programs directory (executable directory),
How to find my programs directory (current directory, "special folders").

Once you get rid of the "~" and get the file path right, check whether the File exists before you try to read it, and do something appropriate if it does not exist:

C#

string YourFilePath = @"C:/SomeDirectory/SomeFile.xml";

if(! File.Exists(YourFilePath))
{
     throw new FileNotFoundException("the XML file does not exist");
}

DirectoryNotFoundException was unhandled
