ListBox GetDirectoryInfo问题

Question

我目前正在VB.net中创建一个文件删除器，虽然由于某些原因我无法将我的文件夹的内容放到列表框中，我的代码如下：

Public Class Form1
    Dim dir = "C:\Users\Limited\Desktop\"
    Private Sub listbox()
        ListBox1.DataSource = _
            My.Computer.FileSystem.GetDirectoryInfo( _
                dir).GetFiles("*.exe")
        ListBox1.DisplayMember = "Name"
        ListBox1.ValueMember = "FullName"
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            My.Computer.FileSystem.DeleteFile(dir + ListBox1.SelectedItem.ToString)
            listbox()
        Catch ex As Exception
            MsgBox(ErrorToString, MsgBoxStyle.Critical)
        End Try
    End Sub
End Class

你忘了.ToList（）

        ListBox1.DataSource = _
            My.Computer.FileSystem.GetDirectoryInfo( _
                dir).GetFiles("*.txt").ToList()
        ListBox1.DisplayMember = "Name"
        ListBox1.ValueMember = "FullName"
