这是一个方式，我抓住文件mp3：

私人字符串get_resource（字符串网址）

{

data_xml = null;

WebClient wc = new WebClient（）;

GZipStream responseStream = new GZipStream（wc.OpenRead（url），CompressionMode.Decompress）;

StreamReader reader = new StreamReader（ responseStream）;

推荐答案

从评论开始到你的问题，如果这是一个ASP.NET Web应用程序;既然你已经在HTML下标记了它，那么更好的选择是流媒体而不是推送URL中的媒体内容。在我看来，这是发送媒体文件最糟糕的方法。相反，我的建议是使用媒体流选项，在页面加载后提交文件，这样文档下载就没有延迟。



流媒体 - 维基百科，免费的百科全书 [< a href =https://en.wikipedia.org/wiki/Streaming_mediatarget =_ blanktitle =New Window> ^ ]



媒体流在这些情况下非常有用，您希望允许客户端收听在线内容。可用的库和框架已经支持从另一个位置下载内容; HTTP流式传输。事实上， < audio> [ ^ ]和 < video> [ ^ ]支持以后通过人机交互流媒体内容的选项。因为你在谈论.mp3文件;



Starting from the comment to your question, if this is an ASP.NET web application; since you have tagged it under HTML, then the better options are to stream the media instead of pushing the media content in the URL. Which, in my opinion is the worst method of sending the media file. Instead, my recommendation is using the media streaming options, to submit the file after the page had loaded, so that there is no delay in document downloading.

Streaming media - Wikipedia, the free encyclopedia[^]

Media streaming is very helpful in these cases, where you want to allow the clients to listen to the online content. The available libraries and frameworks already support to download the content from another location; HTTP streaming. Infact, the HTML elements of <audio>[^] and <video>[^] do support the options to stream the media content later with the human-interaction. Since you're talking about .mp3 files;

<audio src="http://location/to/file.mp3" preload="metadata">
   Browser doesn't support <code>audio</code> element.
</audio>

这只会加载元数据，但会在用户想要加载和播放数据时传输数据。

如果是Windows窗体应用程序，您可以在应用程序中嵌入Windows Media Player，然后将其源添加到存在文件的HTTP URL。这里有一个明确解释的方法，如何：嵌入Windows Media Player在表格上 [ ^ ]。但是，使用URL几乎没有意义。因为，如果您的文件在网上找到，您可以下载该文件。



还有另一种方法，有一个开源产品VLC媒体播放器，它还提供了一个可以在Windows中使用的对象的包装器表格申请。您可以使用该库来构建和呈现从HTTP资源流式传输媒体内容的对象。

This would load the metadata only, but would stream the data once the user wants to load and play the data.

Edit

In case of Windows Forms application, you can either embed a Windows Media Player in the application and then add its source to the HTTP URL, where your file is present. One way to do that is clearly explained here, How to: Embed Windows Media Player on a Form[^]. But then, using the URL makes very little sense. Because, if your file is found somewhere online, you can download the file.

There is yet another method of doing this, there is an open source product VLC media player, which also provides a wrapper around its objects that can be used in the Windows Forms application. You can use that library to build and render the objects that stream the media content from an HTTP resource.
