EventDescriptorCollection.Find(String, Boolean) 方法

定義

使用集合中之指定名稱取得事件的描述。

public:
 virtual System::ComponentModel::EventDescriptor ^ Find(System::String ^ name, bool ignoreCase);
public virtual System.ComponentModel.EventDescriptor Find (string name, bool ignoreCase);
public virtual System.ComponentModel.EventDescriptor? Find (string name, bool ignoreCase);
abstract member Find : string * bool -> System.ComponentModel.EventDescriptor
override this.Find : string * bool -> System.ComponentModel.EventDescriptor
Public Overridable Function Find (name As String, ignoreCase As Boolean) As EventDescriptor

參數

name
String

要從集合中取得的事件名稱。

ignoreCase
Boolean

如果您要忽略事件的大小寫,則為 true,否則為 false

傳回

具有指定名稱的 EventDescriptornull (如果事件不存在)。

範例

下列程式代碼範例會尋找特定的 EventDescriptor。 它會在文字框中列印此 EventDescriptor 元件的類型。 它要求 button1 已在表單上具現化 和 textBox1

private:
   void FindEvent()
   {
      // Creates a new collection and assigns it the events for button1.
      EventDescriptorCollection^ events = TypeDescriptor::GetEvents( button1 );
      
      // Sets an EventDescriptor to the specific event.
      EventDescriptor^ myEvent = events->Find( "Resize", false );
      
      // Prints the event name and event description.
      textBox1->Text = String::Concat( myEvent->Name, ": ", myEvent->Description );
   }
private void FindEvent() {
    // Creates a new collection and assigns it the events for button1.
    EventDescriptorCollection events = TypeDescriptor.GetEvents(button1);
 
    // Sets an EventDescriptor to the specific event.
    EventDescriptor myEvent = events.Find("Resize", false);
 
    // Prints the event name and event description.
    textBox1.Text = myEvent.Name + ": " + myEvent.Description;
 }
Private Sub FindEvent()
    ' Creates a new collection and assigns it the events for button1.
    Dim events As EventDescriptorCollection = TypeDescriptor.GetEvents(button1)
    
    ' Sets an EventDescriptor to the specific event.
    Dim myEvent As EventDescriptor = events.Find("Resize", False)
    
    ' Prints the event name and event description.
    textBox1.Text = myEvent.Name & ": " & myEvent.Description
End Sub
