         Console::WriteLine( objs[ i ] );

      }
   }
   catch ( System::ArrayTypeMismatchException^ ) 
   {
      
      // Not reached, "Mouse" is of the correct type
      Console::WriteLine(  "Exception Thrown" );
   }

   try

      objs[ 2 ] = obj;
   }
   catch ( System::ArrayTypeMismatchException^ ) 
   {

注解

ArrayTypeMismatchException 当系统无法将元素转换为为数组声明的类型时引发。例如，类型元素 String 不能存储在数组中 Int32 ，因为不支持这些类型之间的转换。应用程序通常不需要引发此异常。

以下 Microsoft 中间语言 (MSIL) 指令引发 ArrayTypeMismatchException：

ldelem.<type>
ldelema
stelem.<type>

ArrayTypeMismatchException 使用具有值0x80131503的 HRESULT COR_E_ARRAYTYPEMISMATCH。

有关实例的初始属性值的列表ArrayTypeMismatchException，请参阅ArrayTypeMismatchException构造函数。

构造函数

ArrayTypeMismatchException()	初始化 ArrayTypeMismatchException 类的新实例。
ArrayTypeMismatchException(SerializationInfo, StreamingContext)	用序列化数据初始化 ArrayTypeMismatchException 类的新实例。
ArrayTypeMismatchException(String)	用指定的错误消息初始化 ArrayTypeMismatchException 类的新实例。
ArrayTypeMismatchException(String, Exception)	使用指定的错误消息和对作为此异常原因的内部异常的引用来初始化 ArrayTypeMismatchException 类的新实例。

属性

Data	获取键/值对的集合，这些键/值对提供有关该异常的其他用户定义信息。 (继承自 Exception)
HelpLink	获取或设置指向与此异常关联的帮助文件链接。 (继承自 Exception)
HResult	获取或设置 HRESULT（一个分配给特定异常的编码数字值）。 (继承自 Exception)
InnerException	获取导致当前异常的 Exception 实例。 (继承自 Exception)
Message	获取描述当前异常的消息。 (继承自 Exception)
Source	获取或设置导致错误的应用程序或对象的名称。 (继承自 Exception)
StackTrace	获取调用堆栈上的即时框架字符串表示形式。 (继承自 Exception)
TargetSite	获取引发当前异常的方法。 (继承自 Exception)

方法

Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetBaseException()	当在派生类中重写时，返回 Exception，它是一个或多个并发的异常的根本原因。 (继承自 Exception)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetObjectData(SerializationInfo, StreamingContext)	当在派生类中重写时，用关于异常的信息设置 SerializationInfo。 (继承自 Exception)
GetType()	获取当前实例的运行时类型。 (继承自 Exception)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	创建并返回当前异常的字符串表示形式。 (继承自 Exception)

事件

SerializeObjectState

已过时。

当异常被序列化用来创建包含有关该异常的徐列出数据的异常状态对象时会出现该问题。
