推荐答案

HI。



这个过程有点棘手，你需要建立一个专门的html解析逻辑，具体取决于你所针对的新闻纸网站。



假设你的目标是

http://epaperbeta.timesofindia.com/index.aspx?eid=31808&dt=20150905 [ ^ ]



然后弄明白你如何在这里获得PDF的网址html页面。



只是为了线索我可以告诉你顶部的下载链接可以调用下面的java脚本代码。

HI.

Its a bit tricky process and you need to build a specialized html parsing logic depending on which news paper site you are targeting.

Suppose you are targeting
http://epaperbeta.timesofindia.com/index.aspx?eid=31808&dt=20150905[^]

Then figure out how you get url of PDF inside this html page.

Just for clue I can tell you that download link available at the top which invokes the below java script code.

function downloadpdftest() {
    var getslidevalue = parseInt(sudoSlider.getValue("currentSlide"), 10);
    var nextsudoslider = sudoSlider.getSlide(getslidevalue);
    var nextslideid = nextsudoslider.find('img').attr('src');
    var fPath = nextslideid.toString();
    fPath = fPath.replace(".JPG", ".pdf");
    fPath = fPath.replace(".jpg", ".pdf");
    var currPDFName = fPath.replace("Page", "PagePrint");
    window.open(currPDFName, 'PDF', 'left=150,top=10,width=750,height=700,scrollbars=yes,status=yes');
}

现在尝试使用WebRequest或WebClient通过在c＃中获取此页面的内容来生成currPDFName（pdf url）等级。

然后解析html以生成PDF网址。



一旦获得pdf网址，然后在下面用于下载PDF文件的代码。

Now try to generate currPDFName (pdf url) by fetching the content of this page in c# using WebRequest or WebClient Class.


http://stackoverflow.com/questions/16642196/get-html-code-from-a-website-c-sharp[^]code see


Then parse html to generate PDF url.

Once you get pdf url then below code to download PDF file.

using(WebClient client = new WebClient())
{
    client.DownloadFile("http://www.irs.gov/pub/irs-pdf/fw4.pdf", @"C:\Temp.pdf");
}
