範例

下列ArrayTypeMismatchException程式碼範例示範擲回的案例。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++ )

      }
   }

   {
      
      // ArrayTypeMismatchException is not thrown this time.

備註

ArrayTypeMismatchException當系統無法將元素轉換成陣列的宣告型別時, 就會擲回。ArrayTypeMismatchException is thrown when the system cannot convert the element to the type declared for the array. 例如, 類型String的元素不能儲存Int32在陣列中, 因為不支援這些類型之間的轉換。For example, an element of type String cannot be stored in an Int32 array because conversion between these types is not supported. 應用程式通常不需要擲回此例外狀況。It is generally unnecessary for applications to throw this exception.

下列 Microsoft 中繼語言 (MSIL) 指示會擲ArrayTypeMismatchException回:The following Microsoft intermediate language (MSIL) instructions throw ArrayTypeMismatchException :

  • ldelem.<類型 >ldelem.<type>

  • ldelemaldelema

  • stelem.<type>stelem.<type>

ArrayTypeMismatchException使用 HRESULT COR_E_ARRAYTYPEMISMATCH, 其值為0x80131503。ArrayTypeMismatchException uses the HRESULT COR_E_ARRAYTYPEMISMATCH, which has the value 0x80131503.
