从网址中检索图片

On my ASP.Net page in C#, the user is able to enter an URL (web page). When it's done, I would want to get the picture in this page. For an example of this, go on Facebook and write a status with an URL in it. A panel open with the description of the page AND the picture.

Is there a parser or a little application that I can use for this?

在C#的ASP.Net页面上,用户可以输入URL(网页)。 完成后,我想在此页面中获取图片。 例如,在Facebook上写一个带有URL的状态。 将打开一个包含页面说明和图片的面板。

是否可以使用解析器或小应用程序?

    Look at this post for code on how to retrieve html DOM from an url . Once you get a reference to the IHTMLDocument3 instance, use the getElementsByTagName method to retrieve all IMG tags, and take the first.
