In my project i want to upload image by using WCF

Answer 1

Basically you should use WCF streaming.
[ServiceContract]
public interface ITransferService
{
[OperationContract]
void UploadFile(RemoteFileInfo request);
}
public void UploadFile(RemoteFileInfo request)
{
FileStream targetStream = null;
Stream sourceStream = request.FileByteStream;
string uploadFolder = #"C:\\upload\\";
string filePath = Path.Combine(uploadFolder, request.FileName);
using (targetStream = new FileStream(filePath, FileMode.Create,
FileAccess.Write, FileShare.None))
{
//read from the input stream in 65000 byte chunks
const int bufferLen = 65000;
byte[] buffer = new byte[bufferLen];
int count = 0;
while ((count = sourceStream.Read(buffer, 0, bufferLen)) > 0)
{
// save to output stream
targetStream.Write(buffer, 0, count);
}
targetStream.Close();
sourceStream.Close();
}
}

The easiest way is to convert the image to a byte array before sending it, and then converting it back to an image on the destination site.
Here are two methods for doing just that:
public byte[] ImageToByteArray( Image image)
{
var ms = new MemoryStream();
image.Save(ms, ImageFormat.Png);
return ms.ToArray();
}
public static Image ByteArrayToImage(byte[] byteArray)
{
var ms = new MemoryStream(byteArray);
return Image.FromStream(ms);
}
That means your web service can have a method something like this:
public void UploadImage( byte[] imageData )
{
var image = ByteArrayToImage( imageData );
//save image to disk here, or do whatever you like with it
}
