有没有办法在vb.net中从Textbox - AutoCompleteCustomSource中检索集合项

Imports System.Windows.Forms

Public Class Form1
    Private autoCompleteOptions As New List(Of String)()

    Public Sub New()
        InitializeComponent()

        ' 添加自动完成选项
        autoCompleteOptions.Add("Option 1")
        autoCompleteOptions.Add("Option 2")
        autoCompleteOptions.Add("Option 3")

        ' 将自动完成选项集合分配给TextBox的AutoCompleteCustomSource属性
        TextBox1.AutoCompleteCustomSource.AddRange(autoCompleteOptions.ToArray())

        ' 设置自动完成模式
        TextBox1.AutoCompleteMode = AutoCompleteMode.Suggest
        TextBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
    End Sub

    Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
        Dim userInput As String = TextBox1.Text

        ' 根据用户输入的文本检索匹配的选项
        Dim matchingOptions As IEnumerable(Of String) = autoCompleteOptions.Where(Function(option) option.StartsWith(userInput))

        ' 在控制台输出匹配的选项
        For Each option In matchingOptions
            Console.WriteLine(option)
        Next
    End Sub
End Class
