Question

I’m trying to do something in a console app for a test (based on some code in an HttpHandler in a web app).

Given something like this below which works for my HttpHandler which has HttpContext passed to it:

context.Response.AppendHeader("Content-Length", docContent.Length.ToString());
context.Response.AppendHeader("content-disposition", "attachment; filename=\"" + fileName + "\"");
context.Response.ContentType = MIMEType.MimeType(fileType);
context.Response.OutputStream.Write(docContent, 0, docContent.Length);
context.Response.OutputStream.Flush();

I have part of it, I think and then I get stuck:

WebClient client = new WebClient ();

client.Headers.Add("Content-Length", docContent.Length.ToString());
client.Headers.Add("content-disposition", "attachment; filename=\"" + fileName + "\"");
string ContentType = MIMEType.MimeType(fileType);
// ??
// how to build the response as an output stream from my byte array which has the data ? 

Answer 1

MemoryStream(byte[]) can create a Stream from a byte[].

But a problem is WebClient is designed to issue HTTP requests only. If your goal is to test the server by downloading an attachment, then you’ll need different headers.

If indeed you’re trying to download a file, then try using WebClient.DownloadFile
