Download a File From a External sever through Asp.net & C# -

first,i uploaded file in external server , got url server.now want download uploaded file external server through url got server through asp.net , c#. wrote c# code download file, during process got exception "exception of type 'system.outofmemoryexception' thrown". following c# code wrote download:

double dlsize=0; string url = "http://www.sample.com/download.zip"; \\file size: 75mb int lastindex = url.lastindexof("/"); string tempurlname = url.substring(lastindex + 1, url.length - (lastindex + 1));  webrequest owebrequest = webrequest.create(url); owebrequest.timeout = -1; webresponse owebresponse = owebrequest.getresponse();  if (owebresponse.contenttype != "text/html; charset=utf-8") {     string myfile = owebresponse.headers.get("content-length");     int tempmyfile = convert.toint32(myfile);     double bytes_total = convert.todouble(tempmyfile);     dlsize = convert.todouble(bytes_total / (1024 * 1024));      system.io.memorystream omemorystream = new memorystream();     byte[] buffer = new byte[4096];      using (system.io.stream ostream = owebresponse.getresponsestream())     {         int count = 0;                 {             count = ostream.read(buffer, 0, buffer.length);             omemorystream.write(buffer, 0, count);         } while (count != 0);     }      system.io.filestream ofilestream = new system.io.filestream("c:\documents , settings\arun\desktop\new folder\download.zip", system.io.filemode.create);     omemorystream.writeto(ofilestream);     ofilestream.flush();     ofilestream.close();     omemorystream.flush();     omemorystream.close();     owebresponse.close(); } 

it easier this:

webclient webclient = new webclient(); webclient.downloadfile(remotefileurl, localfilename);
