- Run the solution. Two console applications start.
- Find the Sender application by looking for the one with "Sender" in it's console title and press Enter to send a message. A message is sent that includes a DataBus property that is serialized using a custom serializer.
- The sample uses the
FileShareDataBus. Open the solution folder in Windows Explorer and navigate to the\sub-folder. Each sub-folder within thestorage\ \folder contains serialized data bus properties.storage
The FileShareDataBus does not remove physical attachments once the message has been processed. Apply a custom cleanup-strategy.
Code walk-through
This sample contains three projects:
- Shared - A class library with messages and the custom data bus serializer.
- Sender - A console application responsible for sending large messages.
- Receiver - A console application responsible for receiving large messages from the sender.
Shared project
Look at the custom data bus serializer:
public class BsonDataBusSerializer :
IDataBusSerializer
{
public void Serialize(object databusProperty, Stream stream)
{
using (var writer = CreateNonClosingBinaryWriter(stream))
using (var bsonWriter = new BsonDataWriter(writer))
{
serializer.Serialize(bsonWriter, databusProperty);
}
}
public object Deserialize(Type propertyType, Stream stream)
{
using (var jsonReader = new BsonDataReader(stream))
{
return serializer.Deserialize(jsonReader, propertyType);
}
}
BinaryWriter CreateNonClosingBinaryWriter(Stream stream) =>
new BinaryWriter(
stream,
Encoding.UTF8,
leaveOpen: true);
JsonSerializer serializer = JsonSerializer.Create(
new JsonSerializerSettings
{
TypeNameHandling = TypeNameHandling.All
}
);
public string ContentType => "application/bson";
}
The custom serializer implements IDataBusSerializer.
Sender project
The endpoint in the Sender project is configured to use the custom data bus serializer:
var dataBus = endpointConfiguration.UseDataBus<FileShareDataBus, BsonDataBusSerializer>();
dataBus.BasePath(@"..\..\..\..\storage");
Receiver project
The endpoint in the Receiver project must be configured to use the same custom data bus serializer in order to read data bus properties sent by the Sender endpoint:
var dataBus = endpointConfiguration.UseDataBus<FileShareDataBus, BsonDataBusSerializer>();
dataBus.BasePath(@"..\..\..\..\storage");
