如何使用项目经理在 VB.Net 中生成的 My.Settings 验证设置？

Question

下面的代码不起作用，错误说ValidateSettings方法没有与 delgate 兼容的签名 ' Delgate Sub SettingChangingEventHandler(sender as Object, e as SettingChangingEventArgs) '

将AddressOf ValidateSettings悬停在 [...] AddressOf ValidateSettings上时会出现此错误

    Private Sub ValidateSettings(sender As Object, e As SettingChangingEventArgs)


    End Sub

    Private Sub frm_Settings_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        AddHandler My.Settings.SettingChanging, AddressOf ValidateSettings
        PropertyGrid_Settings.SelectedObject = My.Settings
        CenterToParent()
    End Sub

解决方案是将Imports System.Configuration添加到类中，正如对原始帖子的评论所指出的那样。

Imports System.Configuration
Public Class frm_Settings

    Private Sub ValidateSettings(sender As Object, e As SettingChangingEventArgs)
        'validation and notifying user
        MsgBox(e.NewValue)
    End Sub

    Private Sub frm_Settings_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        AddHandler My.Settings.SettingChanging, AddressOf ValidateSettings
        PropertyGrid_Settings.SelectedObject = My.Settings

        CenterToParent()
    End Sub
