以下代码片段供您参考。

var siteURL =" http：// sp2013 / sites / team" ;; var username =" dennis" ;; var password =" password" ;; var domain =" contoso" ;; var folderRelativeUrl =" / sites / team / DL" ;; var fileName =" Test.pdf" ;; HttpWebRequest request = null; HttpWebResponse response = null; string commandString = string.Empty; commandString = string.Format（" / _ api / web / GetFolderByServerRelativeUrl（'{0}'）/ files（'{1}'）/

值"，folderRelativeUrl，文件名）; Uri uri = new Uri（siteURL + commandString）; //设置HTTP请求请求=（HttpWebRequest）WebRequest.Create（uri）; request.Credentials = new NetworkCredential（用户名，密码，域名）; request.Method = WebRequestMethods.Http.Get; response =（HttpWebResponse）request.GetResponse（）; if（response.ContentLength> 0）response.ContentLength = response.ContentLength; Stream output = response.GetResponseStream（）; using（var fs = new FileStream（" c：\\temp \\" + fileName，FileMode.OpenOrCreate）） output.CopyTo（fs）;

最好的问候，

I am using the following endpoint

url: site url/_api/web/GetFolderByServerRelativeUrl('/Folder Name')/Files('file name')/$value method: GET

It is working fine if I browse the endpoint in the browser. When I tried with httpwebrequest and getresponsestream() function it is not returning the file stream.

Please do the needful

Hi,

The following code snippet for your reference.

var siteURL = "sp2013/sites/team"; var username = "dennis"; var password = "password"; var domain = "contoso"; var folderRelativeUrl = "/sites/team/DL"; var fileName = "Test.pdf"; HttpWebRequest request = null; HttpWebResponse response = null; string commandString = string.Empty; commandString = string.Format("/_api/web/GetFolderByServerRelativeUrl('{0}')/files('{1}')/

value",folderRelativeUrl,fileName); Uri uri = new Uri(siteURL + commandString); //Set up the HTTP Request request = (HttpWebRequest)WebRequest.Create(uri); request.Credentials = new NetworkCredential(username, password, domain); request.Method = WebRequestMethods.Http.Get; response = (HttpWebResponse)request.GetResponse(); if (response.ContentLength > 0) response.ContentLength = response.ContentLength; Stream output = response.GetResponseStream(); using (var fs = new FileStream("c:\\temp\\"+fileName, FileMode.OpenOrCreate)) output.CopyTo(fs);

Or we can also use WebClient with REST APIto download file from document library.
