C# Webclient Stream download file from FTP to local storage -

i've been downloading files ftp server via webclient object .net namespace provides , write bytes actual file via binarywriter. good. however, now, files have dramatically increased in size , i'm worried memory constraints i'd create download stream, create file stream, , line line read download , write file.

i'm nervous since couldn't find nice example of this. here's end result:

var request = new webclient();  // omitted code add credentials, etc..  var downloadstream = new streamreader(request.openread(ftpfilepathuri.tostring())); using (var writestream = file.open(tolocation, filemode.createnew)) {     using (var writer = new streamwriter(writestream))     {         while (!downloadstream.endofstream)         {             writer.write(downloadstream.readline());                           }     } } 

am going incorrect/better way/etc?

have tried following usage of webclient class?

using (webclient webclient = new webclient()) {     webclient.downloadfile("url", "filepath"); } 

update

using (var client = new webclient()) using (var stream = client.openread("...")) using (var file = file.create("...")) {     stream.copyto(file); } 

if want download file explicitly using customized buffer size:

public static void downloadfile(uri address, string filepath) {     using (var client = new webclient())     using (var stream = client.openread(address))     using (var file = file.create(filepath))     {         var buffer = new byte[4096];         int bytesreceived;         while ((bytesreceived = stream.read(buffer, 0, buffer.length)) != 0)         {             file.write(buffer, 0, bytesreceived);         }     } }
