VB.NET中lambda的写法

lambda 或者叫匿名方法

 '有返回值的匿名函数，func前面输入参数，最后一个输出参数
         Dim func1 As Func(Of Integer, Integer) = Function(ByVal i As Integer)
                                                      Return i +
                                                  End Function
         Dim func2 As Func(Of Integer, Integer, Integer) = Function(ByVal i As Integer, ByVal t As Integer)
                                                               Return i * t
                                                           End Function
         Dim func3 As Func(Of Integer, Integer, String) = Function(ByVal i As Integer, ByVal t As Integer)
                                                              Return (i * t).ToString
                                                          End Function
         '无返回值的函数
         Dim act1 As Action(Of String) = Sub(ByVal name As String)
                                             Console.Write("hello," + name)
                                         End Sub
         Console.WriteLine(func1.Invoke())
         Console.WriteLine(func2.Invoke(, ))
         Console.WriteLine(func3.Invoke(, ))
         act1.Invoke("bob")
