以编程方式复制媒体文件 [英] Copying media files programmatically

问题描述

大家好，

我正在开发一个项目，我需要将视频文件上传到服务器.基本上，我已经可以使用WPF在我的项目中获取位置并播放该视频了.

我的想法是要有一个单独的文件夹将文件复制到其中，同时仅将位置路径存储在数据库中，就像我对其他文件(例如图像或xps文档)所做的那样

我尝试用来复制文件的代码是

Hey All,

I am developing a project where I need to upload video files to a server. Basically I already have the means to to get the location and play that video in my project using WPF.

My idea is to have a separate folder to copy the files to, while only storing the location path in my database, as I''ve done with other files (such as images or xps documents)

Code I tried using to copy the file was

OpenFileDialog open = new OpenFileDialog();
                    open.Title = "Upload Research Video";
                    open.Filter = "Media Files |*.mpg; *.mpeg; *.m1v; *.mp2; *.mpa; *.mpe; *.avi; *.wmv";
                    try
                    {
                        if (open.ShowDialog().Value)
                        {
                            SelectedFileName = open.FileName;
                             File.Copy(SelectedFileName, @"C:\Users\Cloud\Desktop\" + open.SafeFileName, true);

                        }
                    }
                    catch { }

但这似乎并没有完全起作用，尽管没有引发异常.我不确定为什么，但是它没有出现在我的桌面上.

我应该如何继续复制媒体文件?如果我能指出正确的方向，我将很高兴，因为我尝试过在线搜索，但并没有太大帮助.

在此先谢谢您.:)

But this did not seem to work exactly, although no exceptions were thrown. I''m not exactly sure why but it did not appear on my desktop.

How should I proceed in copying the media file? I would be happy if I can just be pointed in the right direction, as I''ve tried searching online but it hasn''t helped much.

Thanks in advance.:)

推荐答案

需要检查的几件事:

(1)桌面路径正确吗?

(2)该应用程序是否有写权限?

(3)放置一个断点，看看SelectedFileName 和SafeFileName 是什么.

(4)可能会引发异常，但是由于您的catch块为空而被吞下了.

A few things to check:

(1) Is the path to the desktop correct?

(2) Does the app have permissions to write there?

(3) Put a breakpoint and see what SelectedFileName and SafeFileName are.

(4) Maybe an exception is thrown but gets silently swallowed because of your empty catch block.
