示例1: Example
' 導入命名空間
Imports System.Reflection
Public Class Example
Public Shared Sub Main()
' Create a Type object that represents a one-dimensional
' array of Example objects.
Dim t As Type = GetType(Example).MakeArrayType()
Console.WriteLine(vbCrLf & "Array of Example: " & t.ToString())
' Create a Type object that represents a two-dimensional
' array of Example objects.
t = GetType(Example).MakeArrayType(2)
Console.WriteLine(vbCrLf & "Two-dimensional array of Example: " & t.ToString())
' Demonstrate an exception when an invalid array rank is
' specified.
Try
t = GetType(Example).MakeArrayType(-1)
Catch ex As Exception
Console.WriteLine(vbCrLf & ex.ToString())
End Try
' Create a Type object that represents a ByRef parameter
' of type Example.
t = GetType(Example).MakeByRefType()
Console.WriteLine(vbCrLf & "ByRef Example: " & t.ToString())
' Get a Type object representing the Example class, a
' MethodInfo representing the "Test" method, a ParameterInfo
' representing the parameter of type Example, and finally
' a Type object representing the type of this ByRef parameter.
' Compare this Type object with the Type object created using
' MakeByRefType.
Dim t2 As Type = GetType(Example)
Dim mi As MethodInfo = t2.GetMethod("Test")
Dim pi As ParameterInfo = mi.GetParameters()(0)
Dim pt As Type = pi.ParameterType
Console.WriteLine("Are the ByRef types equal? " & (t Is pt))
' Create a Type object that represents a pointer to an
' Example object.
t = GetType(Example).MakePointerType()
Console.WriteLine(vbCrLf & "Pointer to Example: " & t.ToString())
End Sub
' A sample method with a ByRef parameter.
'
Public Sub Test(ByRef e As Example)
End Sub
End Class
