示例1: Example
' 導入命名空間
Imports System.Reflection
Imports System.Runtime.InteropServices
Public Class Example
' This method is for demonstration purposes.
Public Shared Sub Test(ByRef x As Integer, <Out> ByRef y As Integer)
End Sub
Public Shared Sub Main()
' All of the following display 'True'.
' Define an array, get its type, and display HasElementType.
Dim nums() As Integer = {1, 1, 2, 3, 5, 8, 13}
Dim t As Type = nums.GetType()
Console.WriteLine("HasElementType is '{0}' for array types.", t.HasElementType)
' Test an array type without defining an array.
t = GetType(Example())
Console.WriteLine("HasElementType is '{0}' for array types.", t.HasElementType)
' When you use Reflection Emit to emit dynamic methods and
' assemblies, you can create array types using MakeArrayType.
' The following creates the type 'array of Example'.
t = GetType(Example).MakeArrayType()
Console.WriteLine("HasElementType is '{0}' for array types.", t.HasElementType)
' When you reflect over methods, HasElementType is true for
' ref, out, and pointer parameter types. The following
' gets the Test method, defined above, and examines its
' parameters.
Dim mi As MethodInfo = GetType(Example).GetMethod("Test")
Dim parms() As ParameterInfo = mi.GetParameters()
t = parms(0).ParameterType
Console.WriteLine("HasElementType is '{0}' for ref parameter types.", t.HasElementType)
t = parms(1).ParameterType
Console.WriteLine("HasElementType is '{0}' for <Out> parameter types.", t.HasElementType)
' When you use Reflection Emit to emit dynamic methods and
' assemblies, you can create pointer and ByRef types to use
' when you define method parameters.
t = GetType(Example).MakePointerType()
Console.WriteLine("HasElementType is '{0}' for pointer types.", t.HasElementType)
t = GetType(Example).MakeByRefType()
Console.WriteLine("HasElementType is '{0}' for ByRef types.", t.HasElementType)
End Sub
End Class
