Printing Silently from Windows Service / Web API / Website via C#, print-it Implementation

Print-it is a beautifully written software service which enables to print silently to the printer from a Windows Service / Web API Server / Website Server

A detailed implementation documentation is available here, this came as a great rescue to me in a place where I was struggling to print directly to the printer without opening the printer dialog or without opening the PDF file.

However, I feel to add little more scripts to work with the previous C# versions which I am using, this may be helpful to those who uses lower C# versions

Please note:

Here I am about to describe how to consume the hosted service using lower version of C#

The service accepts the POST request with the following 2 mandatory MultipartFormDataContent

1)    pdfFile

2)    printerPath

 

To begin client code: (C# Version: from 4.5)

// Initialize HttpClient

HttpClient client = new HttpClient();

 

// Initialize MultipartFormDataContent

MultipartFormDataContent form = new MultipartFormDataContent();

 

// Initialize HttpContent

HttpContent content = new StringContent("fileToUpload");

 

 

var printerPathContent = new StringContent(PrinterPath);

 

form.Add(content, "pdfFile", "FileName.pdf");

form.Add(printerPathContent, "printerPath");

 

HttpResponseMessage response = null;

 

// Call the Method via POST

response = (client.PostAsync(URL, form)).Result;

// Fetch the result

var result = response.Content.ReadAsStringAsync().Result;

Task Parallel Library (TPL) and Akka.NET: Differences

Task Parallel Library (TPL) and Akka.NET are both powerful tools in the .NET ecosystem for handling parallelism and concurrency, but they serve different purposes and use different models of computation. Here are some key differences:s 1.    Actor Model vs Task-Based Model: Akka.NET is built around the actor model, where actors are the fundamental units of computation and they communicate by exchanging messages. TPL, on the other hand, is task-based. It's designed to make developers more productive by simplifying the process of adding parallelism and concurrency to applications. TPL uses tasks (which are independently executing work units) and provides various ways to control and coordinate them. 2.    Fault Tolerance: One of the key features of Akka.NET is its built-in fault tolerance. It has a "let-it-crash" philosophy, where the system is designed to self-heal from errors. If an actor fails, its parent actor can decide on the supervision strategy: either to resta

Extension Methods - Advanced

Here we will see how can we use the Extension Methods in advanced manner in other types Imagine you often need to retrieve items from a List based on a custom criterion that the built-in LINQ methods don't cover. Extension Methods for Lists: Filtering based on Custom Criteria And the output would be   Extending Enums: Displaying Descriptive Strings Output: Extending DateTime: Calculating Age     Output: The code samples can be found at https://github.com/oneananda/C_Sharp_Examples/tree/main/ExtensionMethods
