ArrayTypeMismatchException Class
The exception that is thrown when an attempt is made to store an element of the wrong type within an array.
Assembly: mscorlib (in mscorlib.dll)
The ArrayTypeMismatchException type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | ArrayTypeMismatchException() | Initializes a new instance of the ArrayTypeMismatchException class. |
![]() ![]() ![]() | ArrayTypeMismatchException(String) | Initializes a new instance of the ArrayTypeMismatchException class with a specified error message. |
![]() | ArrayTypeMismatchException(SerializationInfo, StreamingContext) | Initializes a new instance of the ArrayTypeMismatchException class with serialized data. |
![]() ![]() ![]() | ArrayTypeMismatchException(String, Exception) | Initializes a new instance of the ArrayTypeMismatchException class with a specified error message and a reference to the inner exception that is the cause of this exception. |
| 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.) |
ArrayTypeMismatchException is thrown when the system cannot convert the element to the type declared for the array. For example, an element of type String cannot be stored in an Int32 array because conversion between these types is not supported. It is generally unnecessary for applications to throw this exception.
The following Microsoft intermediate language (MSIL) instructions throw ArrayTypeMismatchException :
ldelem.<type>
ldelema
stelem.<type>
ArrayTypeMismatchException uses the HRESULT COR_E_ARRAYTYPEMISMATCH, which has the value 0x80131503.
For a list of initial property values for an instance of ArrayTypeMismatchException, see the ArrayTypeMismatchException constructors.
The following code example demonstrates scenarios where ArrayTypeMismatchException is thrown.
using namespace System; int main() { array<String^>^names = { "Dog", "Cat", "Fish"}; array<Object^>^objs = dynamic_cast<array<Object^>^>(names); try { objs[ 2 ] = (Object^)"Mouse"; for ( Int32 i = 0; i < objs->Length; i++ ) { Console::WriteLine( objs[ i ] ); } } catch ( System::ArrayTypeMismatchException^ ) { // Not reached, "Mouse" is of the correct type Console::WriteLine( "Exception Thrown" ); } try { Object^ obj = 13; objs[ 2 ] = obj; } catch ( System::ArrayTypeMismatchException^ ) { // Always reached, 13 is not a string. Console::WriteLine( "New element is not of the correct type" ); } // Set obj to an array of objects instead of an array of strings array<Object^>^objs2 = gcnew array<Object^>(3); try { objs2[ 0 ] = (Object^)"Turtle"; objs2[ 1 ] = 12; objs2[ 2 ] = 2.341; for ( Int32 i = 0; i < objs->Length; i++ ) { Console::WriteLine( objs2[ i ] ); } } catch ( System::ArrayTypeMismatchException^ ) { // ArrayTypeMismatchException is not thrown this time. Console::WriteLine( "Exception Thrown" ); } } /*expected return values: Dog Cat Mouse New element is not of the correct type Turtle 12 2.341 */
