由於共用的事件並未繫結至類別執行個體,因此您無法使用WithEvents,以宣告方式處理共用的事件。 同樣地,您不能使用WithEvents或Handles,處理來自Structure的事件。 在這兩種情況下,您可以使用AddHandler陳述式來處理這些事件。 您無法建立WithEvents變數的陣列。
As a rule, you should use the Visual Basic type conversion functions in preference to the .NET Framework methods such asToString(), either on theConvertclass or on an individual type structure or class. The Visual Basic functions are designed for optimal interaction with Visual Basic code, and...
