Question

我尝试使用Array.SetValue设置嵌套类数组

我有一个非常长的嵌套类处理代码，但我有一个类的数组有问题（我想使用反射）

这是我的代码：

Private Function ReadStruct(Of T As {New, Class})()
        Dim structArray As New T
        Dim structArraynn As Object = structArray
        structArray = readclasses(structArraynn)
        Return structArray
    End Function

Private Function readclasses(ByVal cls as object) as object
Dim obj as object = cls
For Each f As System.Reflection.FieldInfo In cls.GetType().GetFields

很多代码......

Dim obj2() As Object = f.GetValue(obj)
Dim MyInstance As Object = Activator.CreateInstance(Type.GetType(f.FieldType.ToString().Replace("[]", "")))
Dim MyInstance2 As Array = Array.CreateInstance(Type.GetType(f.FieldType.ToString().Replace("[]", "")), obj.Length)
For i As Integer = 1 To obj.Length
        MyInstance2.SetValue(readclasses(MyInstance), i - 1)
Next
MsgBox(MyInstance2.GetValue(0).GetType().GetField("Test").GetValue(MyInstance))

并且这些类定义为以下

class m2
public mm as integer
end class

Class main2
public int(1) as integer
public test(10) as m2
end class

但是如果我在MyInstance2.SetValue之后直接调用msgbox行，它会返回正确的值！

我正在使用vs2013和.net2项目

编辑：事实证明所有测试数组元素都具有相同的值（？为什么？）

Here is an example(.net feddle)

Answer 1

每次在循环中调用activator.createinstance时，我必须为每个数组元素创建一个新实例

Example

Array.SetValue不起作用
