主题：如何实现自动修改上传文件的文件名为创建时间

上传的操作，是你控制的吗？

只要自己写代码才能控制

Dim ftp1 As New FtpClient
ftp1.Host="196.128.143.28"
ftp1.Account = "foxuser"
ftp1.Password = "138238110"
If ftp1.Upload("c:\data\Desert.jpg","/" & Format(date.Now, "yyyyMMddHHmmss") & ".jpg") = True Then
    Messagebox.show("上传完成!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
Else
    Messagebox.show("上传失败!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
End If

Dim ftp1 As New FtpClient
ftp1.Host="127.0.0.1"
ftp1.Account = "test"
ftp1.Password = "test"
ftp1.UTF8 = True
Dim dlg As new OpenFileDialog
dlg.MultiSelect = True
If dlg.ShowDialog = DialogResult.OK Then
    For Each f As String In dlg.FileNames
        Dim finfo As New FileInfo(f)
        If ftp1.Upload(f,"/" & finfo.Name.Replace(finfo.Extension, Format(Date.Now, "yyyyMMddHHmmss") & finfo.Extension)) = True Then
            Messagebox.show("上传完成!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
        Else
            Messagebox.show("上传失败!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
        End If
    Next
End If
ftp1.Close
