This article mainly introduces "what is the WCF channel network transmission technology". In the daily operation, I believe that many people have doubts about what the WCF channel network transmission technology is. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for everyone to answer the doubts about "what is the WCF channel network transmission technology?" Next, please follow the editor to study!

In a network environment where the network bandwidth is small, when WCF communicates between two entities, an information channel is automatically created to transfer the communication, which contains the data request and the corresponding message. WCF uses a special encoder to convert request and response data into a series of bytes.

I have encountered the problem of distributed transfer of large files in my project. After analysis, I consider using WCF channel compression technology to solve this problem. To perform such an encoding, you need to transfer large files (in XML format) from one machine to another, and the connection has a speed limit. Instead of writing a special function that compresses and decompresses, I configure the transport channel to do this, which compresses any reusable contract. I found that the message encoder I wrote was the easiest way to implement the function. The real problem was how to write the message encoder. I didn't find any examples of this application on MSDN. The idea of a message contract encoder is to send and receive information on both sides of the Hook connection. The program is designed with Microsoft Visual Studio 2008 WCF.

Sender: add a method to the code, the method and its parameters are serialized into a WCF channel, the message encoding serialized information will become a byte array, and the byte array sends the transport layer. Receiver: the transport layer receives the byte array, the message encoder parallelizes the byte array to a message, the method and its parameters are parallelized to a WCF channel, and the method is listened.

When the compressed information encoder is added, the method requires a little change. The sender: the method and its parameters are serialized into a WCF channel, and the message contract encodes the information of the internal information coding sequence into a byte array, the message contract encodes the compressed byte array, the second byte array, and the byte array sends the transport layer. The receiver: the transport layer receives the byte array, the byte array encoded by the message contract is decompressed to the second byte array, and the message contract encodes the second byte array message, the method and its parameters are parallelized to the WCF channel, and the method is monitored.

At this point, the study on "what is the WCF channel network transmission technology" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
