InvalidCastException Class
The exception that is thrown for invalid casting or explicit conversion.
Assembly: mscorlib (in mscorlib.dll)
The InvalidCastException type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | 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) | 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. |
| Name | Description | |
|---|---|---|
![]() | Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from 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.) |
![]() ![]() ![]() | StackTrace | Gets a string representation of the immediate frames on the call stack. (Inherited from Exception.) |
![]() | TargetSite | Gets the method that throws the current exception. (Inherited from Exception.) |
| 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 a hash function for a particular type. (Inherited from Object.) |
![]() | GetObjectData | 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.) In XNA Framework 3.0, this member is inherited from Object::GetType(). In Portable Class Library Portable Class Library, this member is inherited from Object::GetType(). |
![]() ![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() ![]() | ToString | Creates and returns a string representation of the current exception. (Inherited from Exception.) |
| 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.) |
InvalidCastException is thrown if:
For a conversion from a Single or a Double to a Decimal, the source value is infinity, Not-a-Number (NaN), or too large to be represented as the destination type.
A failure occurs during an explicit reference conversion.
For an explicit reference conversion to be successful, the source value must be nullptr, or the object type referenced by the source argument must be convertible to the destination type by an implicit reference conversion.
For information on conversions supported by the system, see the Convert class. For errors that occur when the destination type can store source type values, but is not large enough to store a specific source value, see OverflowException exception.
The following Microsoft intermediate language (MSIL) instructions throw InvalidCastException
castclass
refanyval
unbox
InvalidCastException uses the HRESULT COR_E_INVALIDCAST, which has the value 0x80004002.
