. in the design of the Net Framework interception mechanism, there are a variety of message receivers between the client and the object. These message receivers form a linked list, and the client's call object process and call return implement interception, you can customize your own message receivers and insert them into the linked list to complete the pre-processing and post-processing of a call. So how is call interception structured or implemented? in. net has two types of calls, one is cro

A message-based distributed architecture always revolves around messages. For example, you can encapsulate a message as an object, or specify the specification of a message, such as soap, or serialize and deserialize an entity object. The only purpose of these methods is to design the message into a format that both producers and consumers can u
context created for the object. Context attribute allows us to associate a message receipt with an object in the message receipt chain. The property class implements icontextobject and icontextobjectsink as the factory for receiving messages:
Public class calltracingproperty: icontextproperty,Icontributeobjectsink {Public imessagesink getobjectsink (externalbyrefobject O,Imessagesink next ){Return new calltracingaspect (next );}...}The process of creating attributes for the proxy is shown in
All objects sent by the component must implement the iMessage interface to describe the serialization process of an object through the implementation interface. The advantage of custom read/write stream is that it can achieve better performance, however, the disadvantage is that the workload is large. in many application scenarios, the pursuit of performance is not the first, but the hope to save these troubles, in order to cope with this need compone
Beetle. SL provides object-based socket TCP transmission functions other than WCF for Silverlight, although an object is provided to describe the Protocol, if you do not understand the seal of the protocol, it seems that it is more difficult to communicate with other platforms over the network. Although beetle. SL describes the protocol as an object, it is highly flexible. Taking the common header 4-byte message length as an example, a component can describe existing protocols through objects an

IOS 8 and OS X Yosemite have been officially pushed, and FaceTime applications in OS X Yosemite are now supporting dialing and answering calls. As for how to do it, it is the use of iOS 8 iphone through the iphone's cellular connection to transfer the phone. The number of calls you make from your Mac is no different from what you call on your iphone. So how exactly do you want to operate?

You can inherit from RealProxy to define your own Custom RealProxy and write the operations you need to inject into the Invoke method. PIAB adopts such a solution.
