示例1: Example
' 导入命名空间
Imports System.Reflection
Imports Contoso.Libraries
Namespace Contoso.Libraries
Public Class Person
Private _name As String
Public Sub New()
End Sub
Public Sub New(name As String)
Me._name = name
End Sub
Public Property Name As String
Get
Return Me._name
End Get
Set
Me._name = value
End Set
End Property
Public Overrides Function ToString() As String
Return Me._name
End Function
End Class
End Namespace
Module Example
Public Sub Main()
Dim assem As Assembly = GetType(Person).Assembly
Dim p As Person = CType(assem.CreateInstance("Contoso.Libraries.Person"),
Person)
If p IsNot Nothing Then
p.Name = "John"
Console.WriteLine("Instantiated a {0} object whose value is '{1}'",
p.GetType().Name, p)
Else
Console.WriteLine("Unable to instantiate a Person object.")
End If
End Sub
End Module输出：
Instantiated a Person object whose value is 'John'
