File paths and Directory operations in C Sharp (C#) - Mini Project: Build & Apply

File paths and Directory operations

📖 Scenario: You are organizing your computer files for a small project. You want to create folders and check file paths to keep everything neat and easy to find.

🎯 Goal: Build a simple C# program that creates a directory, checks if a file path exists, and lists files in a directory.

📋 What You'll Learn

Create a string variable with a directory path

Create a string variable with a file path

Use Directory.CreateDirectory to create the directory

Use File.Exists to check if the file exists

Use Directory.GetFiles to list files in the directory

Print the results to the console

💡 Why This Matters

🌍 Real World

Managing files and folders is a common task when organizing data, saving reports, or handling user uploads in software.

💼 Career

Understanding file paths and directory operations is essential for software developers, system administrators, and anyone working with file management in applications.

1

Create directory and file path variables

Create a string variable called folderPath with the value "C:\\ExampleFolder" and a string variable called filePath with the value "C:\\ExampleFolder\\example.txt".

C Sharp (C#)

// Create string variables folderPath and filePath with the exact values
// Your code here

Need a hint?

Use double backslashes \\ in the string to represent a single backslash in file paths.

2

Create the directory

Use Directory.CreateDirectory(folderPath) to create the directory at the path stored in folderPath.

C Sharp (C#)

string folderPath = "C:\\ExampleFolder";
string filePath = "C:\\ExampleFolder\\example.txt";
// Create the directory using Directory.CreateDirectory
// Your code here

Need a hint?

Use the Directory.CreateDirectory method and pass folderPath as the argument.

3

Check if the file exists and list files

Create a boolean variable called fileExists and set it to File.Exists(filePath). Then create a string array called files and set it to Directory.GetFiles(folderPath).

C Sharp (C#)

using System.IO;

string folderPath = "C:\\ExampleFolder";
string filePath = "C:\\ExampleFolder\\example.txt";

Directory.CreateDirectory(folderPath);
// Check if the file exists and get list of files
// Your code here

Need a hint?

Use File.Exists to check the file and Directory.GetFiles to get all files in the folder.

4

Print the results

Print the value of fileExists using Console.WriteLine. Then use a foreach loop with variable file to print each file path in the files array.

C Sharp (C#)

using System.IO;

string folderPath = "C:\\ExampleFolder";
string filePath = "C:\\ExampleFolder\\example.txt";

Directory.CreateDirectory(folderPath);

bool fileExists = File.Exists(filePath);
string[] files = Directory.GetFiles(folderPath);

// Print fileExists and each file in files
// Your code here

Need a hint?

Use Console.WriteLine(fileExists) and a foreach loop to print each file path.
