The struggle is real. Somehow I can't download this image

string url = @"https://valgfrigave.dk/image/cache/catalog/200%20kr./Lyngby-glas-whiskey01_1000X1000px_200kr-750x750.jpg";

The return error is

 The remote server returned an error: (404) Not Found.

But if you post the url into a browser, you'll get these whiskey glasses

I've been using WebClient and HttpWebRequest. Tried all of the suggestions an answers from

How do I programmatically save an image from a URL?

(...and alot more...)

But none of them is able to download the image.

EDIT

Below is the code where I try to download the image. The error occurs at client.OpenRead(innUri):

class Program

{

    static void Main(string args)

    {

        string url = @"https://valgfrigave.dk/image/cache/catalog/200%20kr./Lyngby-glas-whiskey01_1000X1000px_200kr-750x750.jpg";

        string fileFullPath = @"C:TEMPImage.jpg";



        using (WebClient client = new WebClient())

        {

            Uri innUri = null;

            Uri.TryCreate(url, UriKind.RelativeOrAbsolute, out innUri);



            try

            {

                client.Headers.Add("Accept-Language", "en-US");

                client.Headers.Add("Accept-Encoding", "gzip, deflate");

                client.Headers.Add("Accept", " text/html, application/xhtml+xml, */*");

                client.Headers.Add("User-Agent", "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)");



                using (Stream stream = client.OpenRead(innUri))

                {

                    using (System.IO.FileStream output = new System.IO.FileStream(fileFullPath, FileMode.Create))

                    {

                        byte buffer = new byte[16 * 1024]; // Fairly arbitrary size

                        int bytesRead;



                        while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) > 0)

                        {

                            output.Write(buffer, 0, bytesRead);

                        }

                    }

                }

            }

            catch (WebException we)

            {

                throw we;

            }

        } 

    }

}

2nd EDIT

Still doesn't work after trying the suggested approach

SOLUTION

A solution has been found and can be seen by the comment from @Stephan Schlecht.
Added the following method and replaced the URI creation:

Method added:

public static Uri MyUri(string url)

{

    Uri uri = new Uri(url);

    System.Reflection.MethodInfo getSyntax = typeof(UriParser).GetMethod("GetSyntax", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.NonPublic);

    System.Reflection.FieldInfo flagsField = typeof(UriParser).GetField("m_Flags", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);

    if (getSyntax != null && flagsField != null)

    {

        foreach (string scheme in new { "http", "https" })

        {

            UriParser parser = (UriParser)getSyntax.Invoke(null, new object { scheme });

            if (parser != null)

            {

                int flagsValue = (int)flagsField.GetValue(parser);

                // Clear the CanonicalizeAsFilePath attribute

                if ((flagsValue & 0x1000000) != 0)

                    flagsField.SetValue(parser, flagsValue & ~0x1000000);

            }

        }

    }

    uri = new Uri(url);

    return uri;

}

Replaced my original code:

    Uri innUri = null;

    Uri.TryCreate(url, UriKind.RelativeOrAbsolute, out innUri);

with:

    //Uri innUri = null;

    //Uri.TryCreate(url, UriKind.RelativeOrAbsolute, out innUri);

    Uri innUri = MyUri(url);

Problem

As already suspected in comments, the problem is that part of the URL, namely a dot, disappears. This seems to be a bug in .NET 3.5.

Here a screenshot of a https proxy: without the dot there is a 404 since this part of the URL is missing:

Solution for .NET 3.5

Since you need to stay on .NET 3.5 you can use this cool workaround from a SO answer: https://stackoverflow.com/a/31559579

In your code add the MyUri method from the link above and change the URI creation like so:

Uri innUri = MyUri(url);

Then the download works!
