C# TCP/UDP Ports List

This is a program which retrieves an up-to-date list of ports (and associated service names/descriptions), for use in applications which require this information. The list is retrieved directly from IANA.

Purpose

The purpose of this program is to retireve information regarding various network services, and provide a means by which this information can be presented to an end user.

It also demonstrates the following concepts in C#:

• Use of HttpClient to retrieve data
• JSON serialization
• Error handling

Usage

Simple usage:

• Download and import the file 'ports.json' into your project.
• Consume it using Newtonsoft.Json or an equivalent method. See the below section for an example of this.

Consumption:

• You can retrieve and deserialize the file using the following code:

using (StreamReader sr = new StreamReader("ports.json"))
{
    string jsonString = sr.ReadToEnd();
    Ports = JsonConvert.DeserializeObject<List<Port>>(jsonString);

}

• An example of the above method is included in Example.cs.

Dynamic usage:

• To ensure your copy of ports.json is always up to date, build and run the program. You may wish to incorporate the method into your application if it requires up-to-date port/service references.
• Clone and modify this project to ensure that the output object (Port.cs) matches your use case.
