Hi, I was looking at this thread: http://stackoverflow.com/questions/1935040/how-to-handle-large-file-uploads-via-wcf
I need to have a web service hosted at my provider where i need to upload and download files to. We are talking videos from 1Mb to 100Mb hence the streaming approach.
I cant get it to work, i declared an Interface:
[ServiceContract]
public interface IFileTransferService
{
[OperationContract]
void UploadFile(Stream stream);
}
and all is fine, i implement it like this:
public string FileName = "test";
public void UploadFile(Stream stream)
{
try
{
FileStream outStream = File.Open(FileName, FileMode.Create, FileAccess.Write);
const int bufferLength = 4096;
byte[] buffer = new byte[bufferLength];
int count = 0;
while((count = stream.Read(buffer, 0, bufferLength)) > 0)
{
//progress
outStream.Write(buffer, 0, count);
}
outStream.Close();
stream.Close();
//saved
}
catch(Exception ex)
{
throw new Exception("error: "+ex.Message);
}
}
Still no problem, its published to my webserver out on the interweb. So far so good.
Now i make a reference to it and will pass it a FileStream, but the argument is now a byte[] - why is that and how do i get it the proper way for streaming?
Edit My binding look like this:
<bindings>
<basicHttpBinding>
<binding name="StreamingFileTransferServicesBinding"
transferMode="StreamedRequest"
maxBufferSize="65536"
maxReceivedMessageSize="204003200" />
</basicHttpBinding>
</bindings>
I can consume it without problems, and get no errors - other than my input parameter has changed from a stream to a byte[]
