Create folder if path does not exist?
提问by user1342164
I am using the code below to save a pdf file to a network location. Is it possible that if the path does not exist that it creates the folder? The code below is just adding the username to the file name when I need it to create the username's folder?
我正在使用下面的代码将 pdf 文件保存到网络位置。如果路径不存在，是否有可能创建文件夹？下面的代码只是在我需要创建用户名文件夹时将用户名添加到文件名中？
Dim Doc1 As New Document
Dim path As String = "\Servername\PDFs\" + Session("Username")
Dim myUniqueFileName = String.Format("{0}.pdf", random)
Dim combinedData As String = path & myUniqueFileName
PdfWriter.GetInstance(Doc1, New FileStream(path & myUniqueFileName, FileMode.Create))
Doc1.Open()
Dim test As String
test = Session("PDF")
Doc1.Add(New Paragraph(test))
Doc1.Close()

Absolutely, like this:
绝对的，像这样：
If(Not System.IO.Directory.Exists(path)) Then
System.IO.Directory.CreateDirectory(path)
End If
