components. In terms of WCF, this component is called a WCF Service. In a more general sense, the WFC service is the software responsible for communicating with the outside world.
A WCF Service consists of the following three parts:
Service Class: A class marked with the [servicecontract] attribute, which may contain multiple methods. Except for marking some unique attributes of WCF, this class is no different from general classes.HOST: it can be an application, such as a Windows service. It i

1: Create a host
In the Main function, we create a ServiceHost host = new ServiceHost (), that is, to create a host, and the service instance corresponding to this host is HelloWorldService. helloWorldService is the implementation class in the first project. ServiceHost host = new ServiceHost (typeof (HelloWorldService. helloWorldService) This code means tha

USB System Structure
1. USB system topology
The topology of the USB system consists of the USB host controller, root hub, hub, and device. The root hub is bound with the USB host controller.
Node represents a USB device. in a broad sense, hub is also a USB device. A usb bus can mount up to 127 devices.
Common USB master controllers:
OHCI (Open Host Controller Interface): it is mainly a non-PC system USB chip and a common controller for embedded systems. USB1.1

spring integration. The code responsible for these connections is the message terminal. This is not to say that you must connect directly to your existing app's code. Any existing enterprise integration solution requires some code for integration related, such as Routing and Protocol translation. One of the key points is to achieve the separation of the integration logic and business logic focus points. In other words, as the MVC pattern in a Web application, the goal should be to provide a sim
The endpoint security service based on cloud is not mature enough to the enterprise Internal Security Service, how to successfully complete the cloud security service at the present stage when the experience and case are not enough? This is a problem that puzzles a lot of CSO.
The so-called win, in addition to their own needs to do a careful consideration, on the other hand, is to understand the supplier's products and services, the two-pronged appro
Speaking of USB devices, we have to mention a variety of descriptors (descriptors), in general, descriptors are as follows:
1: Device Descriptor (Device descriptors)
2: Configuration descriptor (Configuration descriptors)
2: Interface Descriptor (Interface descriptors)
3: Endpoint descriptor (Endpoint descriptors)
A USB device has only one device descriptor, the device descriptor defines how many configurat
Because the MTP protocol is widely used in mobile devices, it becomes one of the necessary components in the device interconnection products. It is easy to imagine a car in the way, access to the car equipment, listen to the songs on the phone, or at rest, borrow a large car screen to see the phone's high-definition movies, which makes the journey easier and more comfortable.This article tries to avoid introducing the MTP protocol (the document has been written clearly), mainly for a specific de
:
Iphostentry iphost = dns.resolve ("www.google.com/");
string[] aliases = iphost.aliases;
Console.WriteLine (aliases. Length);
ipaddress[] addr = iphost.addresslist;
Console.WriteLine (addr. Length);
for (int i= 0; i
{
Console.WriteLine (Addr[i]);
}
After introducing the Iphostentry class, we can get the relevant IP address and alias list of the host we want to connect with, but it also needs a very important class-ipendpoint class to get the connection with the host.

element has the following attributes:
Name: specifies the type of service agreement implementation. It is a fully qualified name (namespace and type name)
BehaviorConfiguration: Specifies the name of the service behavior element found in the behaviors element. The node in the corresponding behaviors is the serviceBehaviors node.
Endpoint specifies the binding, agreement, and address attributes of the service
WCF is a framework used to build service-oriented applications. WCF is a runtime and a group of APIs used to create a system for sending messages between a service and a client. Based on the concept of message-based communication, WCF can represent any content of a message in a unified manner in the programming model.
Message
A message is an independent data unit. It may consist of several parts, including the message body and message header.
Service

You only need to determine whether the horizontal and vertical coordinates of the point are between the left side of the rectangle and the upper and lower sides.
6. Determine whether the line segment, line, and polygon are in the rectangle.
Because the rectangle is a convex set, you only need to determine whether all endpoints are in
