Hi,
While comperessing, it wirks fine, but while decompressing the compressed sting using GZip, I am getting error "The magic number in GZip header is not correct. Make sure you are passing in a GZip stream." Please go through the follwoing code.
string Body = string.Empty;
string strZiped= Zip(Body);
string strUnZiped = UnZip(strZiped);
public static string Zip(string value)
{
byte[] byteArray = new byte[value.Length];
int indexBA = 0;
foreach (char item in value.ToCharArray())
{
byteArray[indexBA++] = (byte)item;
}
//Prepare for compress
System.IO.MemoryStream ms = new System.IO.MemoryStream();
System.IO.Compression.GZipStream sw = new System.IO.Compression.GZipStream(ms,
System.IO.Compression.CompressionMode.Compress);
sw.Write(byteArray, 0, byteArray.Length);
sw.Close();
byteArray = ms.ToArray();
System.Text.StringBuilder sB = new System.Text.StringBuilder(byteArray.Length);
foreach (byte item in byteArray)
{
sB.Append((char)item);
}
ms.Close();
sw.Dispose();
ms.Dispose();
string strCompressed = sB.ToString();
return strCompressed;
}
public static string UnZip(string Compressedvalue)
{
byte[] byteArray = Encoding.UTF8.GetBytes(Compressedvalue);
MemoryStream stream = new MemoryStream(byteArray);
Stream sourceStream = stream;
if (sourceStream == null)
{
throw new ArgumentException();
}
if (!sourceStream.CanRead)
{
throw new ArgumentException();
}
MemoryStream memoryStream = new MemoryStream();
const int bufferSize = 65536;
using (GZipStream gzipStream = new GZipStream(sourceStream, CompressionMode.Decompress))
{
byte[] buffer = new byte[bufferSize];
int bytesRead = 0;
do
{
bytesRead = gzipStream.Read(buffer, 0, bufferSize);
}
while (bytesRead == bufferSize);
memoryStream.Write(buffer, 0, bytesRead);
}
byte[] btArraymemoryStream = memoryStream.ToArray();
string st = Encoding.UTF8.GetString(btArraymemoryStream);
return st;
}
