ArrayTypeMismatchException Constructor

Initializes a new instance of the ArrayTypeMismatchException class.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

This constructor initializes the Message property of the new instance to a system-supplied message that describes the error, such as "Source array type cannot be assigned to destination array type." This message takes into account the current system culture.

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




A null reference (Nothing in Visual Basic).


The localized error message string.

The following example demonstrates the ArrayTypeMismatchException() constructor of the ArrayTypeMismatchException class. It contains a function which takes two arrays as arguments and checks whether the two arrays are of the same type. If the arrays are of different types, a new ArrayTypeMismatchException is thrown and then caught in the calling method.

using namespace System;
public ref class ArrayTypeMisMatchConst
   void CopyArray( Array^ myArray, Array^ myArray1 )
      String^ typeArray1 = myArray->GetType()->ToString();
      String^ typeArray2 = myArray1->GetType()->ToString();

      // Check whether the two arrays are of same type or not. 
      if ( typeArray1 == typeArray2 )

         // Copy the values from one array to another.
         myArray->SetValue( String::Concat(  "Name: ", myArray1->GetValue( 0 )->ToString() ), 0 );
         myArray->SetValue( String::Concat(  "Name: ", myArray1->GetValue( 1 )->ToString() ), 1 );

         // Throw an exception of type 'ArrayTypeMismatchException'. 
         throw gcnew ArrayTypeMismatchException;


int main()
      array<String^>^myStringArray = gcnew array<String^>(2);
      myStringArray->SetValue( "Jones", 0 );
      myStringArray->SetValue( "John", 1 );
      array<Int32>^myIntArray = gcnew array<Int32>(2);
      ArrayTypeMisMatchConst^ myArrayType = gcnew ArrayTypeMisMatchConst;
      myArrayType->CopyArray( myStringArray, myIntArray );
   catch ( ArrayTypeMismatchException^ e ) 
      Console::WriteLine( "The Exception is : {0}", e );
