推荐答案

您需要使用此
删除过滤器中的空格

You need to remove the spaces in your filters use this

fold.Filter = "document files (*.doc)|*.doc|richtext format(*.rtf)|*.rtf|All files (*.*)|*.*"

之间不应有空格文件声明.试试这个

You should not have any spaces between your file declarations. Try this

Using fold As New OpenFileDialog
           fold.Filter = "document files (*.doc)|*.docx|richtextformat files (*.rtf)|*.rtf|All files (*.*)|*.*"
           fold.Title = "Select file"
           If fold.ShowDialog() = Windows.Forms.DialogResult.OK Then
               'fold.FilterIndex = 2
               fold.RestoreDirectory = True
               MessageBox.Show("You selected " & fold.FileName)
           End If
       End Using
