Question

我正在获取文件夹名称，并将pdf文件放在同一目录中，并使用以下代码列在同一个列表框中：

        Private Sub frmBooks_Load(sender As Object, e As EventArgs) Handles MyBase.Load
For Each folder As String In System.IO.Directory.GetDirectories(Application.StartupPath & "\Books")
        ListBox1.Items.Add(Path.GetFileName(folder))
    Next
    For Each file As String In System.IO.Directory.GetFiles(Application.StartupPath & "\Books\", "*.pdf")
        ListBox1.Items.Add(Path.GetFileNameWithoutExtension(file))
    Next

在同一个listbox1中混合和分类然后我添加axacropdf（PDF组件）来读取pdf文件。如何打开/获取列表框中选定项目的路径，以便在axacropdf中打开？

(axacropdf.src =)

此代码检查文件是否以.pdf

存在

Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ListBox1.SelectedIndexChanged
    If File.Exists(Application.StartupPath & "\Books\" & ListBox1.SelectedItem.ToString & ".pdf") = True Then
        AxAcroPDF1.src = (Application.StartupPath & "\Books\" & ListBox1.SelectedItem.ToString & ".pdf")
end if
   end sub

从混合列表框中加载axacropdf（pdf组件）上的文件
