InvalidCastException Constructors

Definition

Namespace:

System

Assembly:

System.Runtime.dll

Initializes a new instance of the InvalidCastException class.

Overloads

InvalidCastException()	Initializes a new instance of the InvalidCastException class.
InvalidCastException(String)	Initializes a new instance of the InvalidCastException class with a specified error message.
InvalidCastException(SerializationInfo, StreamingContext)	Obsolete. Initializes a new instance of the InvalidCastException class with serialized data.
InvalidCastException(String, Exception)	Initializes a new instance of the InvalidCastException class with a specified error message and a reference to the inner exception that is the cause of this exception.
InvalidCastException(String, Int32)	Initializes a new instance of the InvalidCastException class with a specified message and error code.

InvalidCastException()

Source:

InvalidCastException.cs

Initializes a new instance of the InvalidCastException class.

public:
 InvalidCastException();

public InvalidCastException ();

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 "Cannot cast from source type to destination type." This message takes into account the current system culture.

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

Property	Value
InnerException	A null reference (Nothing in Visual Basic).
Message	The localized error message string.

InvalidCastException(String)

Source:

InvalidCastException.cs

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

public:
 InvalidCastException(System::String ^ message);

public InvalidCastException (string? message);

new InvalidCastException : string -> InvalidCastException

Public Sub New (message As String)

Parameters

message

String

The message that describes the error.

Remarks

This constructor initializes the Exception.Message property of the new exception using the message parameter. 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.

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

Property	Value
InnerException	A null reference (Nothing in Visual Basic).
Message	The error message string.

InvalidCastException(SerializationInfo, StreamingContext)

Source:

InvalidCastException.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 InvalidCastException class with serialized data.

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

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

Parameters

info

SerializationInfo

The object that holds the serialized object data.

context

StreamingContext

The contextual information about the source or destination.

Attributes

ObsoleteAttribute

Remarks

This constructor is called during deserialization to reconstitute the exception object transmitted over a stream. For more information, see XML and SOAP Serialization.

InvalidCastException(String, Exception)

Source:

InvalidCastException.cs

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

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

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

new InvalidCastException : string * Exception -> InvalidCastException

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 returns 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 InvalidCastException.

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

InvalidCastException(String, Int32)

Source:

InvalidCastException.cs

Initializes a new instance of the InvalidCastException class with a specified message and error code.

public:
 InvalidCastException(System::String ^ message, int errorCode);

public InvalidCastException (string? message, int errorCode);

new InvalidCastException : string * int -> InvalidCastException

Public Sub New (message As String, errorCode As Integer)

Parameters

message

String

The message that indicates the reason the exception occurred.

errorCode

Int32

The error code (HRESULT) value associated with the exception.

Remarks

This constructor initializes the Exception.Message property of the new exception using the message parameter. 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.

This constructor supplies an HRESULT value that is accessible to inheritors of the InvalidCastException class, via the protected HResult property of the Exception class.

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

Property	Value
InnerException	A null reference (Nothing in Visual Basic).
Message	The error message string.
