I know By using WebClient class we can download the files directly.
By using this code web.DownloadFile("url", "filename");
But in my scenario I should call this(https://www.nseindia.com/reports/gsm) link and when this link triggered the "Download (.csv)" link should download automatically (you can see this download option in image and highlighted with blue color circle)
Note :
if I click on this download link it starting the downloading in the same link and will not not giving the download link separately. So I should call this download link through the coding only.
So how can we achieve this type of file downloading's.
Give me your best suggestions to achieve this.
A general approach to solving problems like this:
Open the network tab on your browser devtools
download the object you want to fetch with your program, and
look for the object's download.
Inspect that object in the network tab to determine its Url.
Then try that URL in your (C#) program.
If you get the object, fine. If you don't, the web site owner may have built anti-scraping protection for the object. For example, you may need to be logged in to the site to access the object.

On a website, I'm successfully using an ASHX handler to download files from the server to visitors of my website.
A customer suggested to not rely on the browser UI to visualize the download progress but instead provide some progress on the page to provide a more visual cue.
I.e. first, the user sees a download page with a link/button:
Then, when clicking the Download your file now! button something like this should appear:
Unfortunately, even after searching Google and SO for hours, I found zero similar topics. All occurrences deal with upload, not download. Either I'm using the wrong keywords or there are really no solutions.
Therefore my question:
(How) would it be possible to provide such a download progress?
I am making a web browser in C Sharp, I want that all the files downloaded by the user on this web browser from any web sites, web browser saves it in one default folder (i.e C:\Users\Abc\Downloads)
Currently when i try to download file from any url it pops up a dialogue box asking for path, and it is annoying thing to have so i just wants to give one default path where it just saves the file automatically without asking user for the path.
Like we have default download path for Mozila firefox and google whenever user download any file from the web browser it saves in one default folder. so how can I achieve this in .net 4.0 Csharp web browser.
I'm afraid you can't with the webbrowser control,
maybe take a look at

first you don't use IE, and you can do more if I'm right

If you're using the WebBrowser control in c# this can be somewhat of a challenge, but have a look at this link which might help you, I've tried it myself with good results.

Good Luck! :)

You might want to look into this solution to your issue as well:
Automated filedownload using WebBrowser without url

I am trying to create a wizard using jquery (fill in a dialog of info, press next, dialog changes but page does not refresh). During this process I would like to upload a file to a document library. I do not wish to reload the page. Is this possible? How would you go about doing this?
You can use uploadify plugin here, which uses a flash component to upload files and it provides events for almost every state of uploading, so you can fire your functions whenever you want for changing content showing alerts etc...
As redsquare says there are also other plugins, but i used this one in a project and it works pretty well.
Hope it helps,

I've been thinking about this and can't seem to find a way to do this:
I've got some code running on WatiN 2.0 which connects to a site via an SSL tunnel, and after performing certain tasks (which there're no other feasible ways to automate without relying on a browser) should be able to download an image from the very same SSL connection. The image is served dynamically depending on some state generated during navigation, and is not served but through the SSL connection associated with the aforementioned state, so I really need to stick with WatiN + IE.
Thanks in advance
If I understand you correctly, you are trying to go to a web page (via multiple steps) and then save a copy of an image (dynamically generated) on that page right?
If so, I don't think there's a way to do this built in to WatiN, but I stumbled across a thread on the WatiN mail list archive which may help.
Basically it looks like you can use WatiN to dynamically generate some javascript to run against your page and copy the image to the clipboard & then grab the image from the clipboard in your test code.
Hope that is of some help to you...
I have a web page which displays some report. When I click on the link for excel, it puts all the data that is displayed on the screen into a CSV file and opens a File Download window which lets me either Open, Save or Cancel.
I want to download this file to a specified location programatically without the user seeing the File Download window. I am using a Windows Application. I dont have the code for the website displaying this report hence dont have the dataset. Also, I looked into the HTML that gets generated by doing a view source on the page but I can't really scrape through it to get the data.
Hence I need to know how to download an excel file from a given website to a location on my computer.
Thanks in advance

Well you'll need to find the appropriate link or post action. You can then use something like:
string url = "http://whatever/.../foo.xsl";
string target = #"c:/excel documents/foo.xsl";
WebClient client = new WebClient();
client.DownloadFile(url, target);
It gets a bit more complicated if you need to authenticate etc though.
I assume that you're showing the web page within a WebBrowser control. You can handle the WebBrowser.Navigating Event and inspect the value of the WebBrowserNavigatingEventArgs URL property to see if string.EndsWith(".csv", CurrentCultureIgnorecase) (or perhaps a more specific test).
If you detect that the link that has been clicked is for a file you wish to download then you can call e.Cancel() = True on the WebBrowserEventArgs instance to stop the browser from proceeding with its normal behavior of opening the File Download dialog. Then you can use .NET's HttpWebRequest and HttpWebResponse classes to manually download the file.
Here's a sample of downloading using these classes
Actually I am doing a screen scraping, so I am not displaying the web page.
What I have done is gone to the URL where the report is displayed on the screen. There is a hyperlink for 'Excel'. I make this hyperlink click from my program itself. On clicking this link, it opens the File Download dialog box.
I have written, the WebBrowser.Navigating and Navigated events, but the control does not come here. Any ideas
1 more thing, the site that I am accessing is java website.
