我正在ASP.NET MVC 5中开发Web应用程序，其中一个想要在其上显示图像的Web。该Web表单应该像dropbox一样工作（如果我将图像放入我的PC文件夹，它可能会自动与我的网站合成）。我只是缺乏做这种事情。任何人请提出一个想法。

I'm Developing web application in ASP.NET MVC 5, One of the web from wants to show an images on it. That web form should work as like dropbox (If i put a image into my PC folder, it may automatically synthesize with my website). i'm just getting lack to do this type of thing. Any one please give an ideas.

推荐答案

你需要的是别的东西。它不是您网站的普通客户端，而是一个功能齐全的应用程序软件，可以管理您的文件系统，同时在服务器上记录您的文档和文件。 Dropbox应用程序在您的文件系统上创建一个要管理的文件夹。监视器会监视其中的所有文件。在实际中，（或在.NET中），您可以使用 FileSystemWatcher [ ^ ]确定何时在该目录中发生更改的对象。 我建议您阅读有关该课程的评论。 您的应用程序需要此对象，以便跟踪该目录或其中的文件发生的情况。然后，您可以执行不同的操作。例如，如果将新文件添加到文件夹，您可以将该文件传递到您的网站（或云？）。 HttpClient [ ^ ]将是一个非常完美的候选人（恕我直言）。 What you need is something else. It is not an ordinary client for your website, instead it is a full featured application software that manages your file system and at the same time keeps a note of your documents and files on the server. Dropbox application creates a folder on your file system to manage. All of the files in it are watched by a watchdog. In real, (or in .NET) you can use a FileSystemWatcher[^] object to determine when a change occurs in that directory. I recommend that you read the remarks about the class. Your application needs this object in order to keep a track of what happens to that directory or the files in it. Then you can perform different actions. For example if a new file is added to the folder, you can pass that file to your website (or cloud?). HttpClient[^] would be a very perfect candidate (IMHO). using (var client = new HttpClient()) { // get the location of that file // POST a multipart/form-data content }

可以在此主题中找到示例： stackoverflow/questions/18059588/httpclient-multipart-form-post- in-c-sharp [ ^ ] 最后，您需要处理请求并捕获内容并上传。一个很长的，但是...我相信如果你只是先将算法放在纸上，然后逐步编写源代码，你就可以完成它。

A sample for that can be found in this thread: stackoverflow/questions/18059588/httpclient-multipart-form-post-in-c-sharp[^] Then finally, you need to handle the request and capture the content and upload it. A long one, but... I am sure if you simply put the algorithm on paper first and then write the source code step-by-step you will be able to get it done.
