I have a webservice that I need to consume files from. The problem is this webservice limits API calls to 100MB but the files are larger then 100MB. So they recommended we use the the Range header. I added the range to the HttpWebRequest. My problem seems to be combining the Streams. I think it stems from the fact that I cannot create a instance of the ConnectSream (which I think is what GetResponseStream returns). So I have to create a MemoryStream instead. Except when I do it this way I try to open a test zip file I uploaded it wont open. I compared the downloaded file with my original copy and the downloaded file has no actual data in it, in a hex view it shows all 0's. How can I fix this so I can combine the two streams and then save the file to the disk?
foreach (var largeFile in LargeFilesToDownload)
{
Stream stream = new MemoryStream();
while (endSize <= largeFile.Value)
{
try
{
HttpWebRequest downReq = (HttpWebRequest)HttpWebRequest.Create("https://webserviceurl/" + largeFile.Key);
downReq.Headers.Add("Authorization", "Bearer " + API_TOKEN);
downReq.AddRange(startSize, endSize);
downReq.Method = "GET";
using (var eresp2 = (HttpWebResponse)downReq.GetResponse())
{
eresp2.GetResponseStream().CopyTo(stream);
}
}
catch (Exception exc)
{
//Handle Exception
}
//Set new startSize and endSize here
}
try
{
//check to make sure path exists here
string path = SaveLocation + #"\" + rootDir + #"\" + Path.GetFileName(largeFile.Key);
using (FileStream file = new FileStream(path, FileMode.Create, System.IO.FileAccess.Write))
{
byte[] bytes = new byte[stream.Length];
stream.Read(bytes, 0, (int)stream.Length);
file.Write(bytes, 0, bytes.Length);
stream.Close();
}
FilesToDelete.Add(largeFile.Key);
}
catch (Exception ex2)
{
//Handle Exception
}

I have a very strange issue. I am converting Image to base64string in an asp.net web API hosted in Azure app service and getting the wrong image string.
If I run the code in the local machine I am getting the correct value.
public static string GetImageFromSharePointOnline(string imageUrl)
{
try
{
using (var clientContext = CreateContext(URL))
{
clientContext.ExecutingWebRequest += ExecutingWebRequest;
FileInformation fileInformation = null;
Stream returnStream = new MemoryStream();
int readCount;
var buffer = new byte[8192];
Uri image = new Uri(imageUrl);
try
{
fileInformation = Microsoft.SharePoint.Client.File.OpenBinaryDirect(clientContext, image.AbsolutePath);
while ((readCount = fileInformation.Stream.Read(buffer, 0, buffer.Length)) != 0)
{
returnStream.Write(buffer, 0, readCount);
}
}
catch (Exception ex) { }
returnStream.Seek(0, SeekOrigin.Begin);
return "data:image/" + GetFileExtensionFromUrl(imageUrl) + ";base64," + Convert.ToBase64String(buffer);
// return Convert.ToBase64String(buffer);
}
}
catch (Exception ex) { }
}
Azure web api output:

Can anyone help me with this please.
You're initializing a MemoryStream:
Stream returnStream = new MemoryStream();
(should be var returnStream = new MemoryStream();)
as the container for the bytes read from a Stream.
The Image bytes are read from the source Stream using a buffer:
var buffer = new byte[8192];
which is ok for a NetworkStream.
Assuming Uri image = new Uri(imageUrl); represents the same object in both environments, you the read a [buffer] number of bytes (which is the maximum value, the actual bytes read may be less than that) and write the bytes read - the value is stored in the readCount variable - to the MemoryStream:
try
{
fileInformation = Microsoft.SharePoint.Client.File.OpenBinaryDirect(clientContext, image.AbsolutePath);
while ((readCount = fileInformation.Stream.Read(buffer, 0, buffer.Length)) != 0)
{
returnStream.Write(buffer, 0, readCount);
}
}
When the source Stream is read to end, the MemoryStream contains the Image bytes.
At this point, you want to convert the Image bytes to a Base64String.
Of course, you need to convert the content of your MemoryStream, returnStream, not the buffer content, which is only used as a temporary container for the bytes coming from the source Stream. So just change:
Convert.ToBase64String(buffer);
to:
Convert.ToBase64String(returnStream.ToArray());
Setting returnStream.Position = 0 before calling returnStream.ToArray() is not necessary in this context, but it doesn't hurt either.
Side note: those empty catch blocks don't serve you well. Either add logging features or remove.
I'm attempting to use National Weather Service (U.S.) data, but something has changed recently and the GZip file no longer opens.
.NET 4.5 complains that...
Message=The magic number in GZip header is not correct. Make sure you are passing in a GZip stream.
Source=System
StackTrace:
at System.IO.Compression.GZipDecoder.ReadHeader(InputBuffer input)
at System.IO.Compression.Inflater.Decode()
at System.IO.Compression.Inflater.Inflate(Byte[] bytes, Int32 offset, Int32 length)
at System.IO.Compression.DeflateStream.Read(Byte[] array, Int32 offset, Int32 count)
I don't understand what has changed, but this is becoming a real show-stopper. Can anyone with GZip format experience tell me what has changed to make this stop working?
A file that works:
http://www.srh.noaa.gov/ridge2/Precip/qpehourlyshape/2015/201504/20150404/nws_precip_2015040420.tar.gz

http://www.srh.noaa.gov/ridge2/Precip/qpehourlyshape/2015/201505/20150505/nws_precip_2015050505.tar.gz
Update with sample code
const string url = "http://www.srh.noaa.gov/ridge2/Precip/qpehourlyshape/2015/201505/20150505/nws_precip_2015050505.tar.gz";

string downloadPath = Path.Combine(appPath, Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "nws_precip_2015050505.tar.gz");
using (var wc = new WebClient())
{
wc.DownloadFile(url, downloadPath);
}
string extractDirPath = Path.Combine(appPath, "Extracted");
if (!Directory.Exists(extractDirPath))
{
Directory.CreateDirectory(extractDirPath);
}
string extractFilePath = Path.Combine(extractDirPath, "nws_precip_2015050505.tar");
using (var fsIn = new FileStream(downloadPath, FileMode.Open, FileAccess.Read))
using (var fsOut = new FileStream(extractFilePath, FileMode.Create, FileAccess.Write))
using (var gz = new GZipStream(fsIn, CompressionMode.Decompress, true))
{
gz.CopyTo(fsOut);
}
It appears that this service SOMETIMES returns tar format files disguised as .tar.gz. This is very confusing, but if you check that the first two bytes are 0x1F and 0x8B, you can detect if the file is a GZip by checking its magic numbers manually.
using (FileStream fs = new FileStream(downloadPath, FileMode.Open, FileAccess.Read))
{
byte[] buffer = new byte[2];
fs.Read(buffer, 0, buffer.Length);
if (buffer[0] == 0x1F
&& buffer[1] == 0x8B)
{
// It's probably a GZip file
}
else
{
// It's probably not a GZip file
}
}
[Resolved] GZipStream complains magic number in header is not correct
//Exception magic number tar.gz file

File is not compress into tar.gz properly
File size is too big , above 1+GB
Solution over it
use .net framework 4.5.1 to over the this exception //OR//
manupulate the exsiting solution without change .net framework.
Please follow the step for implementation.
Remane abc.tar.gz as abc (remove extension).
pass this file and directly name to compress function
*public static void Compress(DirectoryInfo directorySelected, string directoryPath)
{
foreach (FileInfo fileToCompress in directorySelected.GetFiles())
{
using (FileStream originalFileStream = fileToCompress.OpenRead())
{
if ((File.GetAttributes(fileToCompress.FullName) &
FileAttributes.Hidden) != FileAttributes.Hidden & fileToCompress.Extension != ".tar.gz")
{
using (FileStream compressedFileStream = File.Create(fileToCompress.FullName + ".tar.gz"))
{
using (System.IO.Compression.GZipStream compressionStream = new System.IO.Compression.GZipStream(compressedFileStream,
System.IO.Compression.CompressionMode.Compress))
{
originalFileStream.CopyTo(compressionStream);
}
}
FileInfo info = new FileInfo(directoryPath + "\\" + fileToCompress.Name + ".tar.gz");
}
}
}
}
3. implement this code in following exception handler try catch block
try
{
TarGzFilePath=#"c:\temp\abc.tar.gz";
FileStream streams = File.OpenRead(TarGzFilePath);
string FileName=string.Empty;
GZipInputStream tarGz = new GZipInputStream(streams);
TarInputStream tar = new TarInputStream(tarGz);
// exception will occured in below lines should apply try catch
TarEntry ze;
try
{
ze = tar.GetNextEntry();// exception occured here "magical number"
}
catch (Exception extra)
{
tar.Close();
tarGz.Close();
streams.Close();
//please close all above , other wise it will come with exception "tihs process use by another process"
//rename your file *for better accuracy you can copy file to other location
File.Move(#"c:\temp\abc.tar.gz", #"c:\temp\abc"); // rename file
DirectoryInfo directorySelected = new DirectoryInfo(Path.GetDirectoryName(#"c:\temp\abc"));
Compress(directorySelected, directoryPath); // directorySelected=c:\temp\abc , directoryPath=c:\temp\abc.tar.gz // process in step 2 function
streams = File.OpenRead(TarGzFilePath);
tarGz = new GZipInputStream(streams);
tar = new TarInputStream(tarGz);
ze = tar.GetNextEntry();
}
// do anything with extraction with your code
}
catch (exception ex)
{
tar.Close();
tarGz.Close();
streams.Close();
}
I have a asp.net webservice. some functionality of this webservice is to decompress clients request first. for this i have wrote 2 methods one uses MemoryStream and other uses FileStream.
When using MemoryStream sometiomes it get OutofMemoryException. so i have planned to use FileStream instead of MemoryStream for this reason.
before using this i just need a clarification that i am doing the right
thing for the right job.
N:B: Sometiome my clients will send 10MB+ data to the webservice which i need to decompress in webservice side. i have more then 200 clients running. and where the webservice is hosted there are more then 30 web application and webservice also hosted though my webservice is under different app pool.
I did see : GZIP decompression C# OutOfMemory
i get some knowledge from there but for webservice which one should better i have quite confusion based on my situation. and i need a clear understanding about this.
Decompress method (uses MemoryStream) is below:
public static string Decompress(string compressedText)
{
try
{
byte[] gzBuffer = Convert.FromBase64String(compressedText);
using (MemoryStream ms = new MemoryStream())
{
int msgLength = BitConverter.ToInt32(gzBuffer, 0);
ms.Write(gzBuffer, 4, gzBuffer.Length - 4);
byte[] buffer = new byte[msgLength];
ms.Position = 0;
using (GZipStream zip = new GZipStream(ms, CompressionMode.Decompress))
{
zip.Read(buffer, 0, buffer.Length);
}
return Encoding.UTF8.GetString(buffer);
}
}
catch (Exception ex)
{
DataSyncLog.Debug(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType + "::" + System.Reflection.MethodBase.GetCurrentMethod().ToString() + ":" + ex.ToString()+" : "+ex.StackTrace);
}
return string.Empty;
}
Decompress method (uses FileStream) is below:
public static string Decompress(string compressedText)
{
string SourceDirectory = System.Guid.NewGuid().ToString();
string DestinationDirectory = System.Guid.NewGuid().ToString();
try
{
File.WriteAllBytes(SourceDirectory, Convert.FromBase64String(compressedText));
using (FileStream fd = File.Create(DestinationDirectory))
{
using (FileStream fs = File.OpenRead(SourceDirectory))
{
fs.Seek(4, 0);
using (Stream csStream = new GZipStream(fs, CompressionMode.Decompress))
{
byte[] buffer = new byte[1024];
int nRead;
while ((nRead = csStream.Read(buffer, 0, buffer.Length)) > 0)
{
fd.Write(buffer, 0, nRead);
}
}
}
}
return Encoding.UTF8.GetString(File.ReadAllBytes(DestinationDirectory));
}
catch (Exception ex)
{
DataSyncLog.Debug(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType + "::" + System.Reflection.MethodBase.GetCurrentMethod().ToString() + ":" + ex.ToString() + " : " + ex.StackTrace);
return string.Empty;
}
finally
{
ClearFiles(SourceDirectory);
ClearFiles(DestinationDirectory);
}
}
Someone could you please show me the right direction that which one
should i use or any modification needed to the method that uses
MemoryStream that can overcome this error. i will be grateful to you
if you give me a clear understanding about this or any code change
suggestion.
Working with stream looks more efficient memory-wise in the second case: with memory stream you hold entire stream in memory, with file stream you have only buffer of limited size.
Both of your methods can have problems with memory just because of their signature: when client sends 10MB this amount of memory will be allocated for compressedText argument and for return value.
You can look into changing interface of your service, so data is transfered in chunks (here you can find example of similar approach -http://www.codeproject.com/Articles/43272/Uploading-Large-Files-Through-Web-Service)
Or, if you can consider switching to WCF, it supports streaming transfer mode - http://msdn.microsoft.com/en-us/library/ms751463.aspx
Can anyone help with a small problem I am having, I have WCF Rest Based Service, which has function that can accept a stream, this will be used for uplaoding images/audio/video to the server and then storing them on the server somewhere.
Testing with and image, and it appears to work, i select the image in the client, and a few seconds later the image appears on the server in the location expected, but when i try to open the image in windows picture viewer (or any image viewer), i get "No Preview Available", and no image to view.
I am assuming it is because i am not recreating the file again correctly from the stream.
This is the method on the WCF Rest Service
public void PutFileInFolder(int eid, Stream fileContents)
{
try
{
byte[] buffer = new byte[32768];
MemoryStream ms = new MemoryStream();
int bytesRead = 0;
int totalBytesRead = 0;
do
{
bytesRead = fileContents.Read(buffer, 0, buffer.Length);
totalBytesRead += bytesRead;
ms.Write(buffer, 0, bytesRead);
} while (bytesRead > 0);
//now have file in memorystream
//save the file to the users folder
FileStream file = new FileStream(#"C:\bd_sites\ttgme\wwwroot\Evidence\{" + ed.LearnerID + #"}\" + ed.EvidenceFileName, FileMode.Create, System.IO.FileAccess.Write);
byte[] bytes = new byte[ms.Length];
ms.Read(bytes, 0, (int)ms.Length);
file.Write(bytes, 0, bytes.Length);
file.Close();
ms.Close();
}
catch (Exception ex)
{
return;
}
}
And this is the client function for sending the file/image
private void PostFile(EvidenceObject eo)
{
try
{
// Create the REST request.
string url = ConfigurationManager.AppSettings["serviceUrl"];
string requestUrl = string.Format("{0}/PutFileInFolder/{0}", 1001);
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(requestUrl);
request.Method = "POST";
request.ContentType = "text/plain";
byte[] fileToSend = File.ReadAllBytes(txtFileName.Text);
request.ContentLength = fileToSend.Length;
using (Stream requestStream = request.GetRequestStream())
{
// Send the file as body request.
requestStream.Write(fileToSend, 0, fileToSend.Length);
requestStream.Close();
}
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
Console.WriteLine("HTTP/{0} {1} {2}", response.ProtocolVersion, (int)response.StatusCode, response.StatusDescription);
MessageBox.Show("File sucessfully uploaded.", "Upload", MessageBoxButton.OK, MessageBoxImage.Information);
this.DialogResult = true;
}
catch (Exception ex)
{
MessageBox.Show("Error during file upload: " + ex.Message, "Upload", MessageBoxButton.OK, MessageBoxImage.Error);
}
}
Also just tested a video file, the orignal file plays happily, then when i upload it through the service, the file that is created on the server wont play.
I am sure it is somemthing really dumb i am doing, but any help is really appreciated.
The problem was the way i was writing to the file stream, i wasnt actually passing out the bytes of the file, but rather the new bytes making the file the same size but with basically no contents of the original file.
this was the change to the code
//FileStream file = new FileStream(#"C:\bd_sites\ttgme\wwwroot\Evidence\{" + ed.LearnerID + #"}\" + ed.EvidenceFileName, FileMode.Create, System.IO.FileAccess.Write);
//byte[] bytes = new byte[ms.Length];
////ms.Read(buffer, 0, (int)ms.Length);
//file.Write(bytes, 0, bytes.Length);
//file.Close();
//ms.Close();
using (FileStream fs = File.OpenWrite(#"C:\bd_sites\ttgme\wwwroot\Evidence\{" + ed.LearnerID + #"}\" + ed.EvidenceFileName))
{
ms.WriteTo(fs);
fs.Close();
ms.Close();
}
I have been working on this application that enables user to log in into another website, and then download specified file from that server. So far I have succeeded in logging on the website and download the file. But everything ruins when it comes to zip files.
Is there any chunk of code that could be helpful in reading the .zip files byte by byte or by using stream reader?
I m using downloadfile() but its not returning the correct zip file.
I need a method by which I can read zip files. Can I do it by using ByteReader()
The code used to download zip file is
string filename = "13572_BranchInformationReport_2012-05-22.zip";
string filepath = "C:\\Documents and Settings\\user\\Desktop\\" + filename.ToString();
WebClient client = new WebClient();
string user = "abcd", pass = "password";
client.Credentials = new NetworkCredential(user, pass);
client.Encoding = System.Text.Encoding.UTF8;
try
{
client.DownloadFile("https://web.site/archive/13572_BranchInformationReport_2012-05-22.zip", filepath);
Response.Write("Success");
}
catch (Exception ue)
{
Response.Write(ue.Message);
}
Thanks in advance.
is there any chunk of code that could be helpful in reading the zip files bytes by bytes aur by using stream reader.
Absolutely not. StreamReader - and indeed any TextReader is for reading text content, not binary content. A zip file is not text - it's composed of bytes, not characters.
If you're reading binary content such as zip files, you should be using a Stream rather than a TextReader of any kind.
Note that WebClient.DownloadFile and WebClient.DownloadData can generally make things easier for downloading binary content.
Another simple way to downlaod zip file
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/DOWNLOAD/Filename.zip">Click To Download</asp:HyperLink>
Another solution
private void DownloadFile()
{
string getPath = "DOWNLOAD/FileName.zip";
System.IO.Stream iStream = null;
byte[] buffer = new Byte[1024];
// Length of the file:
int length;
// Total bytes to read:
long dataToRead;
// Identify the file to download including its path.
string filepath = Server.MapPath(getPath);
// Identify the file name.
string filename = System.IO.Path.GetFileName(filepath);
try
{
// Open the file.
iStream = new System.IO.FileStream(filepath, System.IO.FileMode.Open,
System.IO.FileAccess.Read, System.IO.FileShare.Read);
// Total bytes to read:
dataToRead = iStream.Length;
// Page.Response.ContentType = "application/vnd.android.package-archive";
// Page.Response.ContentType = "application/octet-stream";
Page.Response.AddHeader("Content-Disposition", "attachment; filename=" + filename);
// Read the bytes.
while (dataToRead > 0)
{
// Verify that the client is connected.
if (Response.IsClientConnected)
{
// Read the data in buffer.
length = iStream.Read(buffer, 0, 1024);
// Write the data to the current output stream.
Page.Response.OutputStream.Write(buffer, 0, length);
// Flush the data to the HTML output.
Page.Response.Flush();
// buffer = new Byte[1024];
dataToRead = dataToRead - length;
}
else
{
//prevent infinite loop if user disconnects
dataToRead = -1;
}
}
}
catch (Exception ex)
{
// Trap the error, if any.
Page.Response.Write(ex.Message);
}
finally
{
if (iStream != null)
{
//Close the file.
iStream.Close();
Page.Response.Close();
}
}
}
Your answer
WebRequest objRequest = System.Net.HttpWebRequest.Create(url);
objResponse = objRequest.GetResponse();
byte[] buffer = new byte[32768];
using (Stream input = objResponse.GetResponseStream())
{
using (FileStream output = new FileStream ("test.doc",
FileMode.CreateNew))
{
int bytesRead;
while ( (bytesRead=input.Read (buffer, 0, buffer.Length)) > 0)
{
output.Write(buffer, 0, bytesRead);
}
}
}
This is how i achieved it. Thanks everyone for ur help
