Net 3 with C to create such named pipes. This article is a how to article showing every step needed and has the code downloadable. Premise I have a need to have one application to provide a messages to another application Inter. Process Communication IPC using a unique named pipe between them using WCF. Named Pipe Library We will be creating three projects. The first will be a library project shown below as Named. Pipe and two test projects not shown in the picture below. The test projects will be the consumers of the library which will be a receiver and a sender talking to each other. The Library will contain the guts of the operations in WCF and once done will look like this in VS2. Solution Explorer This library will be all encompassing and contain the code necessary to perform the named pipe between applications. It handles all the core WCF functionality setupendpoints. All one has to do is have the receiver and sender use the library to communicate by just specifying a name for the pipe. The receiver and sender will simply consume the classes in Receiver. Sender. cs respectively to achieve the named pipe communication. Create a library project named Named. Pipe. Add two references to the System namespaces Runtime. Serialization and Service. Model. Create a folder within the project named Communication, which will be a sub namespace to Named. Pipe. We will place the low level operations and specifications there. Within the Communication folder add an interface class named IPipe. Service as i. Pipe. Service. cs in the downloadable code. Within that file is where we will begin to define the service contract which the sending and receive code will adhere to. The interface code will look like this. System. Collections. Generic. using System. Text. using System. Service. Model. namespace Named. Pipe. Communication. Service. Contract. Omega. Coder. comNamed. Pipe. 1. public interface IPipe. Service. Operation. Contract. void Pipe. InListlt string data. Line 0. 4 We will need to add this using so our attributes will be recognized on the interface. Line 0. 8 This is the attribute which will show our interface to be a specialized WCF contract. Line 1. 0 We setup a generic namespace to avoid naming collisions with other WCF services. This namespace does not have anything to do with opening up the ports, which will have a different URL altogether. This url is kind of a throw away url, we are not publishing to this location. Line 1. 3 We will be opening up one port which we will communicate between the processes and this attribute defines that. Line 1. 4 We will be passing a list of strings between the processes and this method is the vector of the operation. Again within the Communication folder create the second part of the contract, the actual class which will be the catalyst for the data transfer on the receiving side named Pipe. Service as Pipe.

Line 0. 9 This attribute is self explanatory, for this class will be generated for each endpoint we define. In our case only one endpoint for our pipe. Line 1. 0 This is not the default behavior. In standard WCF processing this object would be created through reflection. We dont want that to happen, because we have a delegate call back which will transfer data to the receiver. Due to that fact, we will be creating the object by hand later and allowing the consumer to subscribe to the delegate. Korg Ax3000g Software on this page. Because of that, we have to specify that this context will be a singleton instance. Line 1. 4 Here is the actual url and port which the operations will be operating on. The named part of the port will be added to this string to give us a unique pipe. If we want to expand this to other machines on the intranet, we could use an HTTP protocol as shown below in Line 1. Line 2. 0 Here is where the data will be passed inout. Line 2. 2 Check for a subscriber to the delegate. Line 2. 3 Finally pass the data on to the consumers of the delegate after we have received data from the ether. Line 2. 52. 6 Here is where we will transfer the data back and forth by allowing a consumer to subscribe to this delegate. Receiver Class. Now we will create the top level receiver class as Receiver. That class is created in the top level of the Named. Pipe namespace. Here is the code and the line by line explanation. System. using System. Collections. Generic. System. Text. using System.

Line 0. 4 Even though we have lower level WCF definitions, we will be initiating the WCF functionality in this class. Line 0. 5 Pull in the lower level WCF contract and operations. Line 1. 6 If you know that this is the only named pipe on the system, use a default name for the pipe. Line 2. 0 Otherwise use this constructor to create a named pipe to your specifications. Line 3. 0 Call this after creating the object and after subscribing to the delegate, to start the process of listening. Dont forget to check for a running status. Creating a file in Windows CE 5.
