示例
下面的示例创建 ErrorEventArgs 的新实例，并使用 Exception 对其进行初始化。然后，该示例调用 GetException 来检索 Exception 并显示错误信息。没有与此代码相关联的窗体。
Public Shared Sub Main()
'Creates an exception with an error message.
Dim myException As New Exception("This is an exception test")
'Creates an ErrorEventArgs with the exception.
Dim myErrorEventArgs As New ErrorEventArgs(myException)
'Extracts the exception from the ErrorEventArgs and display it.
Dim myReturnedException As Exception = myErrorEventArgs.GetException()
MessageBox.Show("The returned exception is: " _
+ myReturnedException.Message)
End Sub
public static void Main(string[] args) {
//Creates an exception with an error message.
Exception myException= new Exception("This is an exception test");
//Creates an ErrorEventArgs with the exception.
ErrorEventArgs myErrorEventArgs = new ErrorEventArgs(myException);
//Extracts the exception from the ErrorEventArgs and display it.
Exception myReturnedException = myErrorEventArgs.GetException();
MessageBox.Show("The returned exception is: " + myReturnedException.Message);
}
int main()
{
//Creates an exception with an error message.
Exception^ myException = gcnew Exception( "This is an exception test" );
//Creates an ErrorEventArgs with the exception.
ErrorEventArgs^ myErrorEventArgs = gcnew ErrorEventArgs( myException );
//Extracts the exception from the ErrorEventArgs and display it.
Exception^ myReturnedException = myErrorEventArgs->GetException();
MessageBox::Show( String::Concat( "The returned exception is: ", myReturnedException->Message ) );
}
public static void main(String[] args)
{
//Creates an exception with an error message.
System.Exception myException =
new System.Exception("This is an exception test");
//Creates an ErrorEventArgs with the exception.
ErrorEventArgs myErrorEventArgs = new ErrorEventArgs(myException);
//Extracts the exception from the ErrorEventArgs and display it.
System.Exception myReturnedException = myErrorEventArgs.GetException();
MessageBox.Show("The returned exception is: "
+ myReturnedException.get_Message());
} //main
