如何使openfiledialog.initialdirectory打开整个路径而不仅仅是第一级

问题描述

当我点击一个按钮时，我试图让我的程序打开一个文件夹PHRF List，使用OpenFileDialog.InitialDirectory =C：\ Race \ PHRF List \。该代码将我带到C：\ Race \，但不是下一级文件夹PHRF列表。 InitialDirectory只打开C下面的第一个级别吗？以下是此Sub的完整代码：

When I click a button I am trying to have my program open a folder, "PHRF List", using OpenFileDialog.InitialDirectory = "C:\Race\PHRF List\". The code takes me to "C:\Race\" but not to the next level folder PHRF List. Does InitialDirectory open only the first level below C:? Here is the complete code for this Sub:

Private Sub btnLoadList_Click(sender As Object, e As EventArgs) Handles btnLoadList.Click
       If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
           OpenFileDialog1.InitialDirectory = "C:\Race\PHRF List\"
           OpenFileDialog1.Filter = "txt files(*.txt)|*.txt"                   '
           txtPHRFfile.Text = OpenFileDialog1.FileName
           OpenFileDialog1.RestoreDirectory = True
       End If
       Thread.Sleep(500) 'Enter a delay here
       Using readFile As New StreamReader(txtPHRFfile.Text)
           Do While readFile.Peek() <> -1
               blPHRFstr = readFile.ReadLine()
               listArr = Split(blPHRFstr, ",")
               Me.dgv21.Rows.Add(listArr)
           Loop
           readFile.Close()
           readFile.Dispose()
       End Using
   End Sub

我尝试了什么：



阅读许多在线文章，包括使用InitialDirectory的Microsoft教程但没有尝试多于一个低于C的级别：



还添加了OpenFileDialog.RestoreDirectory但它没有效果。

What I have tried:

Read many on line articles including Microsoft tutorial on using InitialDirectory but none try to go more than one level below C:

Also added OpenFileDialog.RestoreDirectory but it has no effect.

推荐答案

If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
   OpenFileDialog1.InitialDirectory = "C:\Race\PHRF List\"
   OpenFileDialog1.Filter = "txt files(*.txt)|*.txt"                   '
   txtPHRFfile.Text = OpenFileDialog1.FileName
   OpenFileDialog1.RestoreDirectory = True
End If

在设置初始目录之前打开对话框！

试试这个：

You open the dialog before you set the Initial Directory!
Try this:

OpenFileDialog1.InitialDirectory = "C:\Race\PHRF List\"
OpenFileDialog1.Filter = "txt files(*.txt)|*.txt"                   '
If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
   txtPHRFfile.Text = OpenFileDialog1.FileName
   OpenFileDialog1.RestoreDirectory = True
End If
