示例1: Test
' 导入命名空间
Imports System.Reflection
Imports System.Collections.Generic
Public Class Test
Public Shared Sub Main()
Console.WriteLine(vbCrLf & "--- Create a constructed type from the generic Dictionary type.")
' Create a type object representing the generic Dictionary
' type, by omitting the type arguments (but keeping the
' comma that separates them, so the compiler can infer the
' number of type parameters).
Dim generic As Type = GetType(Dictionary(Of ,))
DisplayTypeInfo(generic)
' Create an array of types to substitute for the type
' parameters of Dictionary. The key is of type string, and
' the type to be contained in the Dictionary is Test.
Dim typeArgs() As Type = { GetType(String), GetType(Test) }
' Create a Type object representing the constructed generic
' type.
Dim constructed As Type = generic.MakeGenericType(typeArgs)
DisplayTypeInfo(constructed)
' Compare the type objects obtained above to type objects
' obtained using GetType() and GetGenericTypeDefinition().
Console.WriteLine(vbCrLf & "--- Compare types obtained by different methods:")
Dim t As Type = GetType(Dictionary(Of String, Test))
Console.WriteLine(vbTab & "Are the constructed types equal? " _
& (t Is constructed))
Console.WriteLine(vbTab & "Are the generic types equal? " _
& (t.GetGenericTypeDefinition() Is generic))
End Sub
Private Shared Sub DisplayTypeInfo(ByVal t As Type)
Console.WriteLine(vbCrLf & t.ToString())
Console.WriteLine(vbTab & "Is this a generic type definition? " _
& t.IsGenericTypeDefinition)
Console.WriteLine(vbTab & "Is it a generic type? " _
& t.IsGenericType)
Dim typeArguments() As Type = t.GetGenericArguments()
Console.WriteLine(vbTab & "List type arguments ({0}):", _
typeArguments.Length)
For Each tParam As Type In typeArguments
Console.WriteLine(vbTab & vbTab & tParam.ToString())
Next
End Sub
End Class输出：
--- Create a constructed type from the generic Dictionary type. System.Collections.Generic.Dictionary'2[TKey,TValue] Is this a generic type definition? True Is it a generic type? True List type arguments (2): TKey TValue System.Collections.Generic.Dictionary`2[System.String,Test] Is this a generic type definition? False Is it a generic type? True List type arguments (2): System.String Test --- Compare types obtained by different methods: Are the constructed types equal? True Are the generic types equal? True
