	DirectoryNotFoundException(SerializationInfo, StreamingContext)	Initializes a new instance of the DirectoryNotFoundException class with the specified serialization and context information.
	DirectoryNotFoundException(String)	Initializes a new instance of the DirectoryNotFoundException class with its message string set to message and its HRESULT set to COR_E_DIRECTORYNOTFOUND.
	DirectoryNotFoundException(String, Exception)	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.

	HelpLink	Gets or sets a link to the help file associated with this exception.(Inherited from Exception.)
	HResult	Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception.(Inherited from Exception.)
	InnerException	Gets the Exception instance that caused the current exception.(Inherited from Exception.)
	Message	Gets a message that describes the current exception.(Inherited from Exception.)
	Source	Gets or sets the name of the application or the object that causes the error.(Inherited from Exception.)

Methods

	Name	Description
	Equals(Object)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetBaseException()	When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.(Inherited from Exception.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetObjectData(SerializationInfo, StreamingContext)	When overridden in a derived class, sets the SerializationInfo with information about the exception.(Inherited from Exception.)
	GetType()	Gets the runtime type of the current instance.(Inherited from Exception.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)

Events

	Name	Description
	SerializeObjectState	Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.)

DirectoryNotFoundException uses the HRESULT COR_E_DIRECTORYNOTFOUND which has the value 0x80070003. Note that DirectoryNotFoundException is also thrown when COM interop programs see the HRESULT STG_E_PATHNOTFOUND, which has the value 0x80030003.

If your code does not have PathDiscovery permission, the error message for this exception may only contain file or directory names instead of fully qualified paths.

Examples

The following example shows how to force and recover from a DirectoryNotFoundException.

using System;
using System.IO;

class Program
{

    static void Main(string[] args)
    {
        try
        {

            //  Specify a directory name that does not exist for this demo.
            string dir = @"c:\78fe9lk";

            // If this directory does not exist, a DirectoryNotFoundException is thrown
            // when attempting to set the current directory.
            Directory.SetCurrentDirectory(dir);
        }
        catch (DirectoryNotFoundException dirEx)
        {
			// Let the user know that the directory did not exist.
            Console.WriteLine("Directory not found: " + dirEx.Message);
        }
    }
}
