如何创建将作为参数传递的泛型类型的列表（VB.Net）

Question

say I have two POCOs I'm using in EF code first

Public class C1
    property F1 as integer
End Class

Public class C2
    property F2 as String
End Class

I want to have a function that will create a list either of C1 or C2, to be used in some generic operation, such that

Sub MySub(type_of_class)
    private lst as new List(of type_of_class)
    ...
End Sub

Will either create a list of C1 or of C2.

I know generics are probably the answer by my knowlege is kind of generic :-)

thanks!

Answer 1

Generics is your answer, but there is a lot more to it. Your sub should be:

Public Sub MySub(Of T)()

    Dim MyT As T

    'do stuff with T

End Sub

and called as this

MySub(Of C1)()
