C# Program to display the name of the directory

In C# programming, you can display the name of a directory using the DirectoryInfo class from the System.IO namespace. This class provides properties and methods to work with directory information, including retrieving just the directory name without the full path.

Syntax

Following is the syntax for creating a DirectoryInfo object and accessing the directory name −

DirectoryInfo dir = new DirectoryInfo(directoryPath);
string directoryName = dir.Name;

Parameters

• directoryPath − A string representing the path to the directory

Return Value

The Name property returns a string containing only the name of the directory, without the full path.

Using DirectoryInfo.Name Property

The Name property extracts just the directory name from the full path. For example, if the path is C:\Users\Documents, the Name property will return Documents.

Example

using System.IO;
using System;

public class Program {
    public static void Main() {
        DirectoryInfo dir = new DirectoryInfo(@"D:\new");
        // displaying the name of the directory
        Console.WriteLine("Directory name: " + dir.Name);
    }
}

The output of the above code is −

Directory name: new

Using Multiple Directory Paths

Example

using System.IO;
using System;

public class Program {
    public static void Main() {
        // Different directory paths
        string[] paths = {
            @"C:\Users\Documents",
            @"D:\Projects\WebApp",
            @"/home/user/downloads"
        };
        
        foreach (string path in paths) {
            DirectoryInfo dir = new DirectoryInfo(path);
            Console.WriteLine("Full path: " + path);
            Console.WriteLine("Directory name: " + dir.Name);
            Console.WriteLine();
        }
    }
}

The output of the above code is −

Full path: C:\Users\Documents
Directory name: Documents

Full path: D:\Projects\WebApp
Directory name: WebApp

Full path: /home/user/downloads
Directory name: downloads

Using Current Directory

You can also get the name of the current working directory using Directory.GetCurrentDirectory() method −

Example

using System.IO;
using System;

public class Program {
    public static void Main() {
        // Get current directory path
        string currentPath = Directory.GetCurrentDirectory();
        DirectoryInfo currentDir = new DirectoryInfo(currentPath);
        
        Console.WriteLine("Current directory full path: " + currentPath);
        Console.WriteLine("Current directory name: " + currentDir.Name);
    }
}

The output of the above code is −

Current directory full path: C:\Program Files\dotnet
Current directory name: dotnet

Conclusion

The DirectoryInfo class in C# provides an easy way to extract directory names from full paths using the Name property. This is useful when you need to display or work with just the directory name without the complete path information.
