问题描述

我正在使用WinSCP .NET程序集通过FTP传输文件.几天前,我开发了新的模块来显示PictureBox控件中的图片.我想要实现的是在列表框中或其他任何位置列出图片的路径,然后单击此路径以在PictureBox中打开图片.关键是图片位于我的FTP的远程位置上,我不知道是否可以使用WinSCP(FTP)使用获取其路径,然后使用这些路径在PictureBox中显示给定的图片.有人知道有可能吗?

I am using WinSCP .NET assembly to transfer files by FTP. Couple days ago I developed new module to show pictures in PictureBox control. What I would like to achieve is to list picture's paths inside listbox or whatever else and then when click on this path to be able to open the picture in PictureBox. The point is pictures are on remote location on my FTP and I have no idea is it possible using WinSCP (FTP) to use get their path and then using the paths to show up given picture inside PictureBox. Anyone has idea is it possible or not?

推荐答案

您必须将文件下载到本地临时文件,然后将其加载到图片框中.您不能直接加载远程文件.

You have to download the file to a local temporary file and load the file to the picture box. You cannot load the remote file directly.

' Unique temporary path 
Dim tempPath As String = Path.GetTempFileName()
' Download the image
session.GetFiles(RemotePath.EscapeFileMask(remoteImagePath), tempPath).Check()
' Load tempPath to picture box
<your code here>
' Delete the temporary file
File.Delete(tempPath)

(我不使用VB.NET,因此语法可能不是100%正确)
