I know how to open an internal pdf file :
public ActionResult GetPDF( string filename )
{
return File( filename, "application/pdf", Server.HtmlEncode( filename ) );
}
question is, how to open a PDF file from an other/external website, e.g. http://example.com/mypdffile.pdf
You don't really need a controller action to do this. You could simply:
Open mypdffile.pdf
Of course if you want to hide this address from the user you could use a WebClient to fetch it on the server:
public ActionResult GetPDF()
{
using (var client = new WebClient())
{
var buffer = client.DownloadData("http://www.blabla.com/mypdffile.pdf");
return File(buffer, "application/pdf", "mypdffile.pdf");
}
}
And in your view:
<%= Html.ActionLink("Download PDF", "GetPDF") %>
You will need it locally anyway to do any processing so, you can download it to local folder and then show it. use WebClient or HttpRequest/HttpResponse objects to do the downloading

I have trouble with display a image in my Angular app.
This is in my profile.ts and profile.html page
public createImgPath = (serverPath: string) => {
return `http://localhost:63040/${serverPath}`;
}
<img class="img-responsive" src="{{createImgPath(userApi.user.imageUrl.folderName)}}" />
From the server I get filepath:
var folderName = Path.Combine( "userImages", fileName);
return Ok(new { folderName });
When I try to display image in src I get the path but image is not display.
And I got error message:
It was very silly typo mistake. Instead "usersImages", in var folderName I used to use "userImages". I'm sorry for trouble to everyone.
I think you're supposed to return the file as a blob. Because you cannot send your images as a JSON to angular. Well, at first, change your backend code to something like this:
var folderName = Path.Combine( "userImages", fileName);
return new FileStream(folderName , FileMode.Open, FileAccess.Read);
and then change [HttpGet] to [HttpPost]
I don't know how to send your image file to the backend but I think you can fix your problem with these changes.
I have few links to pdf files store in server in my static page. I would be able to click each link that would open a pdf file in browser. I referred to this link. But it is not working as I intended.
Here is my action method:
public ActionResult GetFileFromServer(string filename)
{
string folderpath = StrGlobal.file_folder.ToString();
string filepath = Path.Combine(folderpath, filename);
filepath = Path.GetfullPath(filepath);
return File(filepath, "application/pdf");
}
My view:
<p>
#Html.ActionLink(
linkText: "ABC Document",
actionName:"GetFileFromServer",
controllerName:"StaticPage",
routeValues:new {filename = "ABC.pdf"},
htmlAttributes:null
)
</p>
If I replace and hardcore filename in this line:
string filepath = Path.Combine(folderpath, "ABC.pdf");
It will open that specific pdf file. Otherwise I get an error saying
Value cannot be null. Parameter name: path2
Seems like value is not getting passed from view to controller. How do I fix this issue?
<a href="/staticpath/ABC.pdf" download>
Donloadpdf

Hi,
We can resolved issue by easy way with using html download functionality.
I'm working in a function to download pdfs from DropBox, I'm using ASP.net Core , everything works good. The only thing is that when you click in the download link it doesn't show any message and downloads the file. I would like to show the download progress like usually happens when we download something from Internet, I don't want any dialog to appear, just to show that the file was downloaded like normally happens in any browser like Chrome or IE and then have the choices 'Show in Folder' and things like that, what would I need to add?
public async Task DownloadPdf()
{
DropboxClient client2 = new DropboxClient("cU5M-a4exaAAAAAAAAABDVZsKdpPteNmwHslOeFEo-HByuOr4v4ONvXoAMCFyOXH");
string folder = "MyFolder";
string file = "Test PDF.pdf";
using (var response = await client2.Files.DownloadAsync("/" + folder + "/" + file))
{
using (var fileStream = System.IO.File.Create(#"C:\Users\User\Downloads\Test.pdf"))
{
(await response.GetContentAsStreamAsync()).CopyTo(fileStream);
}
}
}
I have a asp.net core project with an API that returns a file:
[HttpGet("{id}")]
public IActionResult Get(int id) {
byte[] fileContent = READ_YOUR_FILE();
FileContentResult result = new FileContentResult(fileContent, "application/octet-stream") {
FileDownloadName = id.ToString()
};
return result;
}
If I access in my browser the URL from this API (myapp/api/mycontroller/id), then I can see the file downloading.
I have PDF file placed on different (FILE-Server) server machine, and the IIS machine on which my MVC application is hosted have rights to that File-Server. From IIS machine i can access the file through following URI:
file://file-server/data-folder/pdf/19450205.pdf
I want to enable my MVC app's users to download their respective files by clicking on download link or button. So probably i would have to write some Action for that link/button.
I tried to use File return type for my Action method in following way:
public ActionResult FileDownload()
{
string filePth = #"file://file-server/data-folder/pdf/19450205.pdf";
return File(filePth , "application/pdf");
}
but the above code gives exception of URI not supported.
I also tried to use FileStream to read bytes inside array return that bytes towards download, but FileStream also gives error of not proper "Virtual Path" as the file is not placed inside virtual path, its on separate server.
public ActionResult Download()
{
var document = = #"file://file-server/data-folder/pdf/19450205.pdf";
var cd = new System.Net.Mime.ContentDisposition
{
// for example foo.bak
FileName = document.FileName,
// always prompt the user for downloading, set to true if you want
// the browser to try to show the file inline
Inline = false,
};
Response.AppendHeader("Content-Disposition", cd.ToString());
return File(document.Data, document.ContentType);
}
Thanks for the replies, but both suggestion did not work.
as file needs to be accessed over URI, using FileInfo gives error: URI formats are not supported.
I managed to get this done through following mechanism:
public ActionResult FaxFileDownload()
{
string filePth = #"file://file-server/data-folder/pdf/19450205.pdf";
WebClient wc = new WebClient();
Stream s = wc.OpenRead(filePth);
return File(s, "application/pdf");
}
Thanks to All.
How can i download file from other server and save it at my own using mvc asp.net with c#?
I am only able to read your title, nevertheless:
WebClient client = new WebClient();
client.DownloadFile("http://your-address.com/FileToDonwload.ext", "c:\PathToTheFileToCreate");
should do what you wanted.
i'd use the System.Web.Mvc.FilePathResult along the following lines:
// most controller logic ommitted
public ActionResult DownloadFile(int fileID)
{
// in this example fileID would map to a file location in the database
var item = _repository.GetByKey(fileID);
// item.DocType would equal "application/msword" / "image/jpeg" etc, etc;
return File(item.DocumentLocation, item.DocType);
}
[edit] - ooops, just realised that this will only work on same server/domain, but have left for reference
