严格的选项不允许后期绑定 [英] Option strict disallows late binding

问题描述

我有一个我要引用的对象，但出现错误:
Option Strict不允许后期绑定

在下面的代码中，带下划线的对象是导致错误的原因

I have an object that I''m trying to reference but I get the error:
Option Strict disallows late binding

In the code below, the underlined object is what causes the error

Public Sub Sort(contacts As Object, comparer As Object, fieldName As String, direction As String)
       Dim itemIndex As Integer = 0

       Select Case fieldName
           Case "FirstName"
               If direction = "decend" Then
                   comparer = serializeInfo.OrderByDescending(Function(x) x.FirstName).ToList()
                   For itemIndex = 0 To serializeInfo.Count - 1
                       Console.WriteLine(comparer(itemIndex).FirstName)
                   Next
               Else
                   comparer = serializeInfo.OrderBy(Function(x) x.FirstName).ToList()
               End If

我无法预览正常工作，所以我将代码保持原样.
感谢您的帮助.

我尝试过的事情:

一些铸造
创建对象

I can''t get preview to work so I''m leaving the code as is.
thanks for any help.

What I have tried:

Some casting
Create object

推荐答案

尝试一下

try this

Public Sub Sort(contacts As Object, comparer As List(Of Contact), fieldName As String, direction As String)
