我需要从服务器发送文件到浏览器（Web客户端）c＃（ASP.NET）但是在下载文件时，程序继续执行 . 我尝试使用任务，线程，异步方法......
//Create a WebRequest to get the file
FileWebRequest fileReq = (FileWebRequest)FileWebRequest.Create(this.CaminhoCompleto);
//Create a response for this request
FileWebResponse fileResp = (FileWebResponse)fileReq.GetResponse();
if (fileReq.ContentLength > 0)
fileResp.ContentLength = fileReq.ContentLength;
//Get the Stream returned from the response
stream = fileResp.GetResponseStream();
// prepare the response to the client. resp is the client Response
HttpResponse resp = HttpContext.Current.Response;
//ERRO!!!
teste(stream, resp, fileResp);
string nomeArq = fileResp.ResponseUri.Segments[(fileResp.ResponseUri.Segments.Length) - 1];
//Indicate the type of data being sent
resp.ContentType = "application/octet-stream";
//Name the file
resp.AddHeader("Content-Disposition", "attachment; filename=\"" + nomeArq + "\"");
resp.AddHeader("Content-Length", fileResp.ContentLength.ToString());
//await stream.CopyToAsync(resp.OutputStream);

使用Iframe从服务器请求文件 . 您可以使用JavaScript创建一个，并使其src成为服务器 endpoints . 当内容准备好下载时，它将从浏览器打开保存对话框 .
