InvalidEnumArgumentException InvalidEnumArgumentException InvalidEnumArgumentException InvalidEnumArgumentException Class

定義

使用為列舉值的無效引數時,會將例外狀況 (Exception) 擲回。The exception thrown when using invalid arguments that are enumerators.

public ref class InvalidEnumArgumentException : ArgumentException
[System.Serializable]
public class InvalidEnumArgumentException : ArgumentException
type InvalidEnumArgumentException = class
    inherit ArgumentException

範例

下列程式碼範例顯示如何攔截InvalidEnumArgumentException例外狀況並解讀其內容。The following code example shows how to catch an InvalidEnumArgumentException exception and interpret its content. 此範例會嘗試透過 cast 傳遞不正確列舉MessageBoxButtons值 () MessageBox.Show做為方法的第三個引數。The example attempts to pass an invalid enumeration value (MessageBoxButtons) through casting, as the MessageBox.Show method's third argument. 攔截到例外狀況之後, 此範例會提取各自的錯誤訊息、不正確參數、堆疊追蹤, 以及例外狀況的來源。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

備註

如果您將不正確列舉值傳遞給方法, 或在設定屬性時, 就會擲回這個例外狀況。This exception is thrown if you pass an invalid enumeration value to a method or when setting a property.
