在VB中,泛型编程可以通过定义泛型类、泛型接口和泛型方法来实现。
定义泛型类:在类的声明前面加上Of关键字和类型参数列表来定义泛型类。例如:Public Class GenericClass(Of T) Private _value As T Public Sub New(value As T) _value = value End Sub Public Function GetValue() As T Return _value End FunctionEnd Class定义泛型接口:在接口的声明前面加上Of关键字和类型参数列表来定义泛型接口。例如:Public Interface IGenericInterface(Of T) Function GetValue() As TEnd Interface定义泛型方法:在方法的声明前面加上Of关键字和类型参数列表来定义泛型方法。例如:Public Sub PrintValue(Of T)(value As T) Console.WriteLine(value)End Sub使用泛型类、泛型接口和泛型方法时,可以通过指定具体的类型参数来实例化类、实现接口或调用方法,例如:
Dim intClass As New GenericClass(Of Integer)(10)Console.WriteLine(intClass.GetValue())Dim strClass As New GenericClass(Of String)("Hello")Console.WriteLine(strClass.GetValue())Dim intList As New List(Of Integer)()intList.Add(1)intList.Add(2)Dim doubleList As New List(Of Double)()doubleList.Add(1.5)doubleList.Add(2.5)Dim genericList As New List(Of T)()genericList.AddRange(intList)genericList.AddRange(doubleList)
