DirectoryNotFoundException()

Source:

DirectoryNotFoundException.cs

Initializes a new instance of the DirectoryNotFoundException class with its message string set to a system-supplied message and its HRESULT set to COR_E_DIRECTORYNOTFOUND.

public:
 DirectoryNotFoundException();

public DirectoryNotFoundException ();

Public Sub New ()

Examples

The following code example demonstrates how to call the DirectoryNotFoundException constructor.

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);
        }
    }
}

Imports System.IO

Module Module1
    Sub Main()
        Try

            ' Specify a directory name that does not exist for this demo.
            Dim dir As String = "c:\78fe9lk"

            ' If this directory does not exist, a DirectoryNotFoundException is thrown
            ' when attempting to set the current directory.
            Directory.SetCurrentDirectory(dir)

        Catch ex As System.IO.DirectoryNotFoundException

            ' Let the user know that the directory did not exist.
            Console.WriteLine("Directory not found: " + ex.Message)
        End Try
    End Sub
End Module

Remarks

This constructor initializes the Exception.Message property of the new instance to a system-supplied message that describes the error, such as "Could not find the specified directory." This message takes into account the current system culture.

The Exception.InnerException property of the new instance is initialized to null.

DirectoryNotFoundException(SerializationInfo, StreamingContext)

Source:

DirectoryNotFoundException.cs

Caution

This API supports obsolete formatter-based serialization. It should not be called or extended by application code.

Initializes a new instance of the DirectoryNotFoundException class with the specified serialization and context information.

protected:
 DirectoryNotFoundException(System::Runtime::Serialization::SerializationInfo ^ info, System::Runtime::Serialization::StreamingContext context);

[System.Obsolete("This API supports obsolete formatter-based serialization. It should not be called or extended by application code.", DiagnosticId="SYSLIB0051", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
protected DirectoryNotFoundException (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context);

[<System.Obsolete("This API supports obsolete formatter-based serialization. It should not be called or extended by application code.", DiagnosticId="SYSLIB0051", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
new System.IO.DirectoryNotFoundException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> System.IO.DirectoryNotFoundException

Protected Sub New (info As SerializationInfo, context As StreamingContext)

Parameters

info

SerializationInfo

The SerializationInfo that holds the serialized object data about the exception being thrown.

context

StreamingContext

The StreamingContext that contains contextual information about the source or destination.

DirectoryNotFoundException(String, Exception)

Source:

DirectoryNotFoundException.cs

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(System::String ^ message, Exception ^ innerException);

public DirectoryNotFoundException (string? message, Exception? innerException);

new System.IO.DirectoryNotFoundException : string * Exception -> System.IO.DirectoryNotFoundException

Public Sub New (message As String, innerException As Exception)

Parameters

message

String

The error message that explains the reason for the exception.

innerException

Exception

The exception that is the cause of the current exception. If the innerException parameter is not null, the current exception is raised in a catch block that handles the inner exception.

Remarks

An exception that is thrown as a direct result of a previous exception should include a reference to the previous exception in the InnerException property. The InnerException property returns the same value that is passed into the constructor, or null if the InnerException property does not supply the inner exception value to the constructor.

The following table shows the initial property values for an instance of DirectoryNotFoundException.

Property	Value
InnerException	The inner exception reference.
Message	The error message string.
