推荐答案

好吧，我确定有很多方法，但这也许会有所帮助. >
以下所有内容均已更改为VB.Net for OP.

首先在您的设置文件中创建一个新属性
1)在解决方案资源管理器中右键单击您的项目
2)点击属性
3)单击设置选项卡
4)添加一个名为CheckedListState的新属性，并将其类型设置为string

然后使用下面的代码(修改以供您使用)

Well I am sure there are many ways but maybe this will help.

All below changed to VB.Net for the OP.

First create a new property in your settings file
1) Right click your project in the solution explorer
2) Click on properties
3) Click on settings tab
4) Add a new property called CheckedListState and set its type to string

Then use below code (modify for your use)

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Dim checkedStates As String() = My.MySettings.Default.CheckedListState.Split(New Char() {","c}, StringSplitOptions.RemoveEmptyEntries)

    For i As Integer = 0 To checkedStates.Length - 1
        CheckedListBox1.SetItemChecked(i, Boolean.Parse(checkedStates(i)))
    Next
End Sub

Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles MyBase.FormClosing
    My.MySettings.Default.CheckedListState = ""
    For i As Integer = 0 To CheckedListBox1.Items.Count - 1
        My.MySettings.Default.CheckedListState += CheckedListBox1.GetItemChecked(i).ToString() & ","
    Next

    My.MySettings.Default.Save()
End Sub

询问我对这段代码是否有任何疑问，我会尽力帮助您解决.

Ask me if you have any questions about this code and I will try to help you figure it out.

您不保存控件，而是保留控件的状态和值.是的，可以将其存储在您的app.config

You don''t save a control, you persist the controls state and values. Yes, it is possible to have this stored in you app.config

中，您无法保存整个控件.您可以将CheckBoxList的状态保存到应用程序中.该配置文件以XML格式存储数据，您可以从中检查CheckBox的状态是否为Checked.
