Question

如何从Visual Basic中的FTP服务器上的文件中修改日期？

这是我到目前为止所做的：

Dim request = CType(WebRequest.Create(URL + ZipFile), FtpWebRequest)
request.Method = WebRequestMethods.Ftp.GetDateTimestamp

之后我尝试了几行，但实际上都没有返回日期。

好吧我明白了，但是我会把它留在这里，因为我找不到任何关于此的其他vb.net帖子：

Imports System.Net
Imports System.Globalization

Dim request = CType(WebRequest.Create(URL + ZipFile), FtpWebRequest)
request.Method = WebRequestMethods.Ftp.GetDateTimestamp
Dim response = CType(request.GetResponse(), FtpWebResponse)
Dim ServerDate = DateTime.ParseExact(response.StatusDescription.Substring(4,14),"yyyyMMddHHmmss",_
                                     Cultureinfo.InvariantCulture,DateTimeStyles.None)

Private Function ServerDateFile(FtpFullPathFile) As Date
        Dim request As FtpWebRequest = WebRequest.Create(FtpFullPathFile)
        request.Credentials = New NetworkCredential( YourFtpUserName, YourPassWord)
        request.Method = WebRequestMethods.Ftp.GetDateTimestamp

        Dim dLastModified As Date = Date.MinValue 'Change for your default value or nothing

        Try
            Using response As FtpWebResponse = request.GetResponse()
                dLastModified = response.LastModified                   
            End Using
        Catch ex As WebException
            MsgBox(ex.Message, vbCritical)
        End Try

        Return dLastModified
    End Function

FTP文件最后修改了VB.NET
