Named Pipes Helper

Simple library to work with named pipes for IPC communication.

Also includes a helper to assist with creating single instance applications and forwarding messages between them.

See example code Here

Getting started

Install package Nuget package

Install-Package NamedPipes.Helper

Server

Listen for messages on pipe named 'MyPipeName' with 2 threads

_server = new Server("MyPipeName", (mesage) =>
{
    Console.WriteLine(message);
});

_server.Start(2);

Client

Publish message to pipe named 'MyPipeName'

Async

await Client.SendMessageAsync("MyPipeName","a test message");

Synchronise

Client.SendMessage("MyPipeName","a test message");

Single Instance Application

Only allow single instance of app

internal static class Program
{
    static Form1? _form;
    
    [STAThread]
    static void Main(string[] args)
    {
        ApplicationConfiguration.Initialize();

        App.SingleInstance("MyAppId", () =>
        {
            _form = new Form1();
            Application.Run(_form);

        });
    }
}

Only allow single instance of app and send message to already running instance

internal static class Program
{
    static Form1? _form;
    
    [STAThread]
    static void Main(string[] args)
    {
        ApplicationConfiguration.Initialize();

        App.SingleInstance("MyAppId", () =>
        {
            _form = new Form1();
            Application.Run(_form);

        },(mesage)=> {
            _form?.Invoke(()=> _form.ShowMessage(mesage));
        }, args.Length> 0 ?
        $"Another instance started with args : {string.Join(" ", args)}" 
        : "Another instance started with no args");
    }
}
