-- 作者:ouyangfenghuan -- 发布时间:2023/12/20 22:04:00 -- 如何修改文心一言的vb代码,适配狐表可用? 求修改下面代码让狐表可以用 vb Imports System.IO Imports System.Net Public Class Form1 Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load \' 设置FTP服务器地址、用户名和密码 Dim ftpServer As String = "ftp.example.com" Dim username As String = "your_username" Dim password As String = "your_password" \' 创建FtpWebRequest对象并设置被动模式 Dim request As FtpWebRequest = (FtpWebRequest.Create(ftpServer & "/") As FtpWebRequest) request.Method = WebRequestMethods.Ftp.ListDirectoryDetails request.UsePassive = True request.Credentials = New NetworkCredential(username, password) \' 发送请求并获取响应 Dim response As FtpWebResponse = request.GetResponse() Dim reader As StreamReader = New StreamReader(response.GetResponseStream()) \' 读取响应并显示文件列表 Dim lines() As String = reader.ReadToEnd().Split(vbCrLf) For Each line As String In lines If line.Contains("drwxr-xr-x") Then \' 目录 Console.WriteLine("Directory: " & line) ElseIf line.Contains("-rwxr-xr-x") Then \' 文件 Console.WriteLine("File: " & line) End If Next \' 关闭连接并释放资源 reader.Close() response.Close() End Sub End Class 在上面的代码中,我们首先设置FTP服务器的地址、用户名和密码。然后,我们创建一个FtpWebRequest对象并设置被动模式。接下来,我们发送请求并获取响应。最后,我们读取响应并显示文件列表。注意,在显示文件列表时,我们假设只有目录和文件两种类型。实际上,FTP服务器返回的文件列表可能包含更多信息。你可以根据需要调整代码以处理其他类型的文件信息。

-- 作者:有点蓝 -- 发布时间:2023/12/21 10:58:00 -- 把命名空间补上呀 Using localFileStream As io.FileStream = New io.FileStream(localPath, io.FileMode.Create) 如果不懂什么是命名空间,百度一下 如果不知道是什么样的命名空间,去微软文档里搜索https://learn.microsoft.com/zh-cn/dotnet/api/system.io.filemode?view=net-8.0,或者打开vs查看
