asp.net - 如何在asp.net中制作文件夹并使用将文件上传到其中
问题描述
我已经使用 ASP.NET 开发了 Web 管理文档。我对如何根据“用户配置文件”制作特定文件夹感到困惑。所以架构喜欢当用户上传他们的文档时，它会根据他们的个人资料自动创建一个文件夹（例如：如果 Admin Finance 上传他们的文档，它会自动创建一个文件夹名称“Finance”并将文件上传到它，但它只为第一次）。对于上传文件，我使用 AjaxUploader。
下面是我使用 Ajax Uploader 上传的代码：
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="FileUpload_Preview.aspx.vb" Inherits="MRISO_FileUpload.FileUpload_Preview" %>
<%@ Register Namespace="CuteWebUI" Assembly="CuteWebUI.AjaxUploader" TagPrefix="CuteWebUI" %>

以下是创建文件夹代码：
Dim path As String = "F:\Upload Document Dept\ " & Session("profile")
If Not (Directory.Exists(path)) Then
Directory.CreateDirectory(path)
lblMsg.Text = "Folder Succesfully create."
Else
lblMsg.Text = "Directory already exists."
End If
我不知道如何让它一起工作，就像我上面说的那样。请帮帮我。感谢 ：）
