Dear Student ,

As per requirement submitted above kindly find below solution.

Here new Windows Forms Application in C# is created using visual studio 2019 with name "DebugProgram".This application contains a class "DebugFourteen1.cs".Below are the details of this class.

DebugFourteen1.cs :

//namespace
using System;
using static System.Console;
using System.IO;
//application namespace
namespace DebugProgram
{
class DebugFourteen1 //C# class
{
//entry point main() method
static void Main(string[] args)
{
//declaring variables
string fileName;
string directory;
string path;
string[] files;
int x;
Write("Enter a directory: ");//asking user to enter directory
directory = ReadLine();//reading directory
//checking directory
if (Directory.Exists(directory))
{
files = Directory.GetFiles(directory);//get all directory
if (files.Length == 0)
//if directory doesnot exists
WriteLine("There are no files in " + directory);
else
{
//print directory
WriteLine(directory + " contains the following files");
for (x = 0; x < files.Length;x++) //using for loop
WriteLine(" " + files[x]);
Write("\nEnter a file name: ");//asking file name
fileName = ReadLine();//reading file
path = directory + "/" + fileName;
//checking file
if (File.Exists(path))
{
//if file exists
WriteLine(" File exists and was created " + File.GetCreationTime(path));
WriteLine("File was created " + File.GetCreationTime(fileName));//display time
}
else
//if file does not exists
WriteLine(" " + fileName + " does not exist in the " + directory, " directory");
}
}
else
{
//if directory does not exits
WriteLine("Directory " + directory + " does not exist");
}
}
}
}
