First im downloading this html as html file:
http://www.sat24.com/en/eu?ir=true
There there is animation of 9 different images/gifs. I want to download each gif url. So on the hard disk i will get 9 gifs.
When reading the file http://www.sat24.com/en/eu?ir=true in the content inside i see:
var imageUrls = ["/image2.ashx?region=eu&time=201309162345&ir=true","/image2.ashx?region=eu&time=201309162330&ir=true","/image2.ashx?region=eu&time=201309162315&ir=true","/image2.ashx?region=eu&time=201309162300&ir=true","/image2.ashx?region=eu&time=201309162245&ir=true","/image2.ashx?region=eu&time=201309162230&ir=true","/image2.ashx?region=eu&time=201309162215&ir=true","/image2.ashx?region=eu&time=201309162200&ir=true","/image2.ashx?region=eu&time=201309162145&ir=true"];
And inside the List: imagesUrls i see this 9 urls:
For example this is in index 0 : image2.ashx?region=eu&time=201309162345&ir=true I tried without the image2.ashx? But in both cases im getting an error on the line:
client.DownloadFile(imagesUrls[i], UrlsPath + "Image" + counter.ToString("D6"));
ArgumentException Illegal characters in path
Before this when i used the test.html and the two other tags start and end it was working without any problem.
But now im using test1.html and this two tags: test("image2.ashx", "ir=true"); But getting the exception.
When i took one image url for example : image2.ashx?region=eu&time=201309170015&ir=true And tried to surf to it in chrome im getting no rsults it tried to search for it in google .
Its not even a url .
This is the full exception error:
System.ArgumentException was unhandled
HResult=-2147024809

InnerException:
Then how can i download the images one by one from this url ? http://www.sat24.com/en/eu?ir=true
When i used the test.html and the startTag ""http://www.niederschlagsradar.de/images.aspx": and endTag: ""cultuur=en-GB&continent=europa"" It worked perfect !
But now with test1.html and the two different tags its not working.
