FileNotFoundException()

Source:

FileNotFoundException.cs

Initializes a new instance of the FileNotFoundException class with its message string set to a system-supplied message.

public:
 FileNotFoundException();

public FileNotFoundException ();

Public Sub New ()

Remarks

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

 FileNotFoundException(System::String ^ message);

public FileNotFoundException (string? message);

new System.IO.FileNotFoundException : string -> System.IO.FileNotFoundException

Public Sub New (message As String)

Parameters

FileNotFoundException(SerializationInfo, StreamingContext)

Source:

FileNotFoundException.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 FileNotFoundException class with the specified serialization and context information.

protected:
 FileNotFoundException(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 FileNotFoundException (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.FileNotFoundException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> System.IO.FileNotFoundException

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

Parameters

info

SerializationInfo

An object that holds the serialized object data about the exception being thrown.

context

StreamingContext

An object that contains contextual information about the source or destination.

FileNotFoundException(String, Exception)

Source:

FileNotFoundException.cs

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

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

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

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

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

Parameters

message

String

A description of the error. The content of message is intended to be understood by humans. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

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 FileNotFoundException.

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

FileNotFoundException(String, String)

Source:

FileNotFoundException.cs

Initializes a new instance of the FileNotFoundException class with a specified error message, and the file name that cannot be found.

public:
 FileNotFoundException(System::String ^ message, System::String ^ fileName);

public FileNotFoundException (string? message, string? fileName);

new System.IO.FileNotFoundException : string * string -> System.IO.FileNotFoundException

Public Sub New (message As String, fileName As String)

Parameters

message

String

A description of the error, or null to use a system-supplied message with the given fileName. The content of message should be understood by humans. The caller of this constructor must ensure that this string has been localized for the current system culture.

fileName

String

The full name of the file with the invalid image.

Remarks

The constructor initializes the Message property of the new instance using message and the FileName property using fileName.

FileNotFoundException(String, String, Exception)

Source:

FileNotFoundException.cs

Initializes a new instance of the FileNotFoundException class with a specified error message, the file name that cannot be found, and a reference to the inner exception that is the cause of this exception.

public:
