[SerializableAttribute]
[ComVisibleAttribute(true)]
public class ArrayTypeMismatchException : SystemException

NameDescription
System_CAPS_pubmethodArrayTypeMismatchException()

Initializes a new instance of the ArrayTypeMismatchException class.

System_CAPS_protmethodArrayTypeMismatchException(SerializationInfo, StreamingContext)

Initializes a new instance of the ArrayTypeMismatchException class with serialized data.

System_CAPS_pubmethodArrayTypeMismatchException(String)

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

System_CAPS_pubmethodArrayTypeMismatchException(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.

NameDescription
System_CAPS_pubpropertyData

Gets a collection of key/value pairs that provide additional user-defined information about the exception.(Inherited from Exception.)

System_CAPS_pubpropertyHelpLink

Gets or sets a link to the help file associated with this exception.(Inherited from Exception.)

System_CAPS_pubpropertyHResult

Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception.(Inherited from Exception.)

System_CAPS_pubpropertyInnerException

Gets the Exception instance that caused the current exception.(Inherited from Exception.)

System_CAPS_pubpropertyMessage

Gets a message that describes the current exception.(Inherited from Exception.)

System_CAPS_pubpropertySource

Gets or sets the name of the application or the object that causes the error.(Inherited from Exception.)

System_CAPS_pubpropertyStackTrace

Gets a string representation of the immediate frames on the call stack.(Inherited from Exception.)

System_CAPS_pubpropertyTargetSite

Gets the method that throws the current exception.(Inherited from Exception.)

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetBaseException()

When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.(Inherited from Exception.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetObjectData(SerializationInfo, StreamingContext)

When overridden in a derived class, sets the SerializationInfo with information about the exception.(Inherited from Exception.)

System_CAPS_pubmethodGetType()

Gets the runtime type of the current instance.(Inherited from Exception.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Creates and returns a string representation of the current exception.(Inherited from Exception.)

NameDescription
System_CAPS_proteventSerializeObjectState

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 System;

namespace ArrayTypeMismatch
{
    class Class1
    {
        static void Main(string[] args) 
        {
            string[] names = {"Dog", "Cat", "Fish"};
            Object[] objs  = (Object[]) names;

            try 
            {
                objs[2] = "Mouse";

                foreach (object animalName in objs) 
                {
                    System.Console.WriteLine(animalName);
                }
            }
            catch (System.ArrayTypeMismatchException) 
            {
                // Not reached; "Mouse" is of the correct type.
                System.Console.WriteLine("Exception Thrown.");
            }

            try 
            {
                Object obj = (Object) 13;
                objs[2] = obj;
            }
            catch (System.ArrayTypeMismatchException) 
            {
                // Always reached, 13 is not a string.
                System.Console.WriteLine(
                    "New element is not of the correct type.");
            }

            // Set objs to an array of objects instead of 
            // an array of strings.
            objs  = new Object[3];
            try 
            {
                objs[0] = (Object) "Turtle";
                objs[1] = (Object) 12;
                objs[2] = (Object) 2.341;

                foreach (object element in objs) 
                {
                    System.Console.WriteLine(element);
                }
            }
            catch (System.ArrayTypeMismatchException) 
            {
                // ArrayTypeMismatchException is not thrown this time.
                System.Console.WriteLine("Exception Thrown.");
            }
        }
    }
}
