Represents the errors that occur when a path that is not valid is returned from the operating system.

Inheritance

System.Object
System.Exception
System.SystemException
System.IO.IOException
System.IO.DirectoryNotFoundException

Summary

This exception is thrown when the system cannot find a directory, or a part of the specified path is invalid. This can happen for various reasons, including typos in the path, attempting to access a non-existent directory, or permissions issues that prevent the directory from being found.

Syntax

public class DirectoryNotFoundException : IOException

Constructors

DirectoryNotFoundException()

Initializes a new instance of the DirectoryNotFoundException class.

DirectoryNotFoundException(string message)

Initializes a new instance of the DirectoryNotFoundException class with a specified error message.

public DirectoryNotFoundException(string message)
Parameters:
  • message: The error message that explains the reason for the exception.

DirectoryNotFoundException(string message, Exception innerException)

Initializes a new instance of the DirectoryNotFoundException class with a specified error message and a reference to the inner exception that is the cause of this exception.

public DirectoryNotFoundException(string message, Exception innerException)
Parameters:
  • message: The error message that explains the reason for the exception.
  • innerException: The exception that is the cause of the current exception. If innerException is not null, the last exception thrown in a catch block that detects the exception is assigned to the InnerException property.

Remarks

The DirectoryNotFoundException is typically thrown by methods that operate on directories, such as Directory.GetFiles or Directory.Delete, when the specified directory path is invalid or does not exist.

When an exception is thrown as a result of a run-time error, the Exception object is thrown with the DirectoryNotFoundException value. The DirectoryNotFoundException class provides information about the error.

Example


using System;
using System.IO;

public class Example
{
    public static void Main(string[] args)
    {
        string nonExistentDirectory = "C:\\This\\Path\\Does\\Not\\Exist";

        try
        {
            // Attempt to list files in a non-existent directory
            string[] files = Directory.GetFiles(nonExistentDirectory);
            Console.WriteLine("Files found: {0}", files.Length);
        }
        catch (DirectoryNotFoundException ex)
        {
            Console.WriteLine("Error: {0}", ex.Message);
            Console.WriteLine("The directory '{0}' was not found.", nonExistentDirectory);
        }
        catch (Exception ex)
        {
            Console.WriteLine("An unexpected error occurred: {0}", ex.Message);
        }
    }
}
