示例

下面的代码示例演示如何捕获InvalidEnumArgumentException异常并解释其内容。The following code example shows how to catch an InvalidEnumArgumentException exception and interpret its content. 该示例尝试通过强制转换传递无效的枚举MessageBoxButtons值 () MessageBox.Show作为方法的第三个参数。The example attempts to pass an invalid enumeration value (MessageBoxButtons) through casting, as the MessageBox.Show method's third argument. 捕获到异常时, 此示例将提取各自的错误消息、无效参数、堆栈跟踪和异常的源。Upon catching the exception, the example fetches the respective error message, the invalid parameter, stack trace, and origin of the exception.

try
{
   //Attempting to pass an invalid enum value (MessageBoxButtons) to the Show method
   MessageBoxButtons myButton = (MessageBoxButtons)123; // to fix use System::Windows::Forms::DialogResult::OK;

   MessageBox::Show( this,  "This is a message",  "This is the Caption", myButton );
}
catch ( InvalidEnumArgumentException^ invE ) 
{
   Console::WriteLine( invE->Message );
   Console::WriteLine( invE->ParamName );
   Console::WriteLine( invE->StackTrace );
   Console::WriteLine( invE->Source );
}
try 
{
// Attempts to pass an invalid enum value (MessageBoxButtons) to the Show method
    MessageBoxButtons myButton= (MessageBoxButtons) 123;
    MessageBox.Show("This is a message","This is the Caption",myButton);
}
catch(InvalidEnumArgumentException invE) 
{
    Console.WriteLine(invE.Message);
    Console.WriteLine(invE.ParamName);
    Console.WriteLine(invE.StackTrace);
    Console.WriteLine(invE.Source);
}
Try
    ' Attempts to pass an invalid enum value (MessageBoxButtons) to the Show method
    Dim myButton As MessageBoxButtons
    myButton = CType(123, MessageBoxButtons)
    MessageBox.Show("This is a message", "This is the Caption", myButton)
Catch invE As System.ComponentModel.InvalidEnumArgumentException
    Console.WriteLine(invE.Message)
    Console.WriteLine(invE.ParamName)
    Console.WriteLine(invE.StackTrace)
    Console.WriteLine(invE.Source)
End Try

注解

如果向方法传递无效的枚举值, 或在设置属性时传递无效的枚举值, 则会引发此异常。This exception is thrown if you pass an invalid enumeration value to a method or when setting a property.
