VB.Net-その他のオペレーター

VB.Netでサポートされている他の重要な演算子はほとんどありません。

Operator	Description	Example
AddressOf	Returns the address of a procedure.	`AddHandler Button1.Click, AddressOf Button1_Click`
Await	It is applied to an operand in an asynchronous method or lambda expression to suspend execution of the method until the awaited task completes.	`Dim result As res = Await AsyncMethodThatReturnsResult() Await AsyncMethod()`
GetType	It returns a Type object for the specified type. The Type object provides information about the type such as its properties, methods, and events.	`MsgBox(GetType(Integer).ToString())`
Function Expression	It declares the parameters and code that define a function lambda expression.	`Dim add5 = Function(num As Integer) num + 5 'prints 10 Console.WriteLine(add5(5))`
If	It uses short-circuit evaluation to conditionally return one of two values. The If operator can be called with three arguments or with two arguments.	`Dim num = 5 Console.WriteLine(If(num >= 0, "Positive", "Negative"))`

例

次の例は、これらの演算子の一部を示しています-

Module assignment
   Sub Main()
      Dim a As Integer = 21
      Console.WriteLine(GetType(Integer).ToString())
      Console.WriteLine(GetType(Double).ToString())
      Console.WriteLine(GetType(String).ToString())

      Dim multiplywith5 = Function(num As Integer) num * 5
      Console.WriteLine(multiplywith5(5))
      Console.WriteLine(If(a >= 0, "Positive", "Negative"))
      Console.ReadLine()
   End Sub
End Module

上記のコードをコンパイルして実行すると、次の結果が生成されます-

System.Int32
System.Double
System.String
25
Positive
