我有一个类似下面代码的事件处理程序：
viewer.LocalReport.SubreportProcessing += new Microsoft.Reporting.WebForms.SubreportProcessingEventHandler(LocalReport_SubreportProcessing);
此方法作为上述事件处理程序的参数：
private static void LocalReport_SubreportProcessing(object sender, SubreportProcessingEventArgs e) {
DateTime movementDate = Convert.ToDateTime(e.Parameters[0].Values[0]);
TourTransactionsController controller = new TourTransactionsController();
var movement = controller.Movements();
List<Movement> movementList = new List<Movement>();
movementList.Add(new Movement {
Destination = "TEST",
MovementDescription = "TEST",
DateTime = Convert.ToDateTime("2017-09-25")
});
e.DataSources.Clear();
e.DataSources.Add(new Microsoft.Reporting.WebForms.ReportDataSource() {
Name = "DSMovements",
Value = movementList
});
//throw new NotImplementedException();
}
这两种方法都是用 WEB API Controller 编写的。事件处理程序在调试时正在按下，但是在我按下F11（步入）后调试LocalReport_SubreportProcessing方法没有按下时。为什么LocalReport_SubreportProcessing方法无法击中？
非常感谢任何帮助或回答。

当您注册/ module.config.php namespace Application;
return [
//...
// myroute1 will route to IndexController fooAction if the route is matching '/index/foo' but regardless of request method
'myroute1' => [
'type' => Zend\Router\Http\Literal::class,
'options' => [
'route' => '/index/foo',
'defaults' => [
'controller' => Controller\IndexController::class,
'action' => 'foo',
],
],
],
// myroute2 will route to IndexController fooAction if the route is request method is GET but regardless of requested route
'myroute2' => [
'type' => Zend\Router\Http\Method::class,
'options' => [
'verb' => 'get',
'defaults' => [
'controller' => Controller\IndexController::class,
'action' => 'foo',
],
],
],
//...
];
时，系统不会调用事件。
当拥有的类调用它时会调用事件。
add当事件触发时，将调用您的处理程序。
注册+=或public class EventTest
{
void SomeOperation()
{
//Do something
}
public void Run()
{
SomeOperation();
RunFinished?.Invoke(this, EventArgs.Empty); //Invoke the event, indicating that something has happened or finished
}
//The event itself
public event EventHandler RunFinished;
}
public class EventSubscriber
{
EventTest _ET = new EventTest();
public EventSubscriber()
{
_ET.RunFinished += ETRunFinished; //Register my method, called when the event occurs (is invoked)
}
public void DoSomething()
{
_ET.Run();
Console.WriteLine("Something completed.");
}
void ETRunFinished(object sender, EventArgs e)
{
Console.WriteLine("My event handler was executed.");
}
}
取消注册（添加/删除）时，不会调用它们。
