Energy.Core 18.3.0

Energy.Core is a .NET library which boosts your program with static functionality covering various type conversions, database abstraction layer, object mapping and simple application framework. Useful to build simple console applications, services, websites or even big applications.

Filled with radioactive rays and made with love for you...

Designed for all purposes as a set of libraries compiled into one include file. No external dependencies (almost), available for main .NET platform versions. Including .NET 2 or Compact Framework but also available for new .NET Core platform.

Installation

The easiest way is install using nuget either by finding Energy.Core package in official gallery or by executing command.

Install-Package Energy.Core

Installation package contains versions for .NET 4, .NET Standard / .NET Core and legacy .NET 2. Nuget should choose apropriate version automatically.

Examples

Safely converting value types

Conversion functions are located in Energy.Base.Cast class. These functions will try to convert value to desired type or use defaults if value cannot be converted.

int numberInt = Energy.Base.Cast.StringToInteger("123");
long numberLong = Energy.Base.Cast.StringToLong("1234567890");
double numberDouble = Energy.Base.Cast.StringToDouble("3.1415"); // or "3,1415"
Console.WriteLine(Energy.Base.Cast.DoubleToString(numberDouble));

Last will always result in culture invariant version "3.1415".

Displaying bytes in pretty format

byte[] array = Energy.Base.Random.GetRandomByteArray(40);
Console.WriteLine(Energy.Base.Hex.Print(array));

Which may result in example output.

2c c5 31 be  de 96 fb 5a  76 53 b7 84  2c 09 8d 16   ,.1....ZvS..,...
88 0f c5 6c  50 c3 69 51  48 99 4b 9f  53 00 79 89   ...lP.iQH.K.S y.
1d c9 de c6  4a c9 dc e2                             ....J...

This was very basic usage but you may extend it with different formatting options, offsets and even coloring.

Waiting for user input on console

When you call Console.ReadLine() program will stop and wait for user input. If you want to stop only when user enters data, use Energy.Core.Tilde.ReadLine() which will result in null as long as user has not accepted its input by pressing Enter key allowing your program to do its job.

Easily make REST requests

How about:

string url = "https://www.google.com/search?q=Energy";
Console.WriteLine(Energy.Core.Web.Get(url).Body);

Easy to use, build upon standard System.Net.WebRequest class REST functions available for common methods like GET, POST, PUT, PATCH, DELETE, HEAD or OPTIONS.

Generic SQL database connection

Here database connection is made using general connection class cooperating with each ADO.NET provider of the database connection.

Energy.Source.Connection<MySql.Data.MySqlClient.MySqlConnection> db
    = new Energy.Source.Connection<MySql.Data.MySqlClient.MySqlConnection>();
db.ConnectionString = @"Server=127.0.0.1;Database=test;Uid=test;Pwd=test;";
if (!db.Test())
{
    Console.WriteLine("Connection test error");
}
else
{
    string result = db.Scalar<string>("SELECT CURRENT_TIMESTAMP()");
    Console.WriteLine("Current server time is: {0}", result);
}

Connections are thread safe, may be cloned or even set to be persistent if you want to limit connections to your SQL database.

Content

Library has been divided into several different namespaces. Following table briefly describes the purpose of each of them.

• Energy.Base - Contains base classes
• Energy.Core - Library functions
• Energy.Attribute - Attributes
• Energy.Enumeration - Enumerations
• Energy.Interface - Interfaces
• Energy.Source - Database connection

History

Working for many years on different development projects, from simple applications, web applicatons, to a rich and monolithic production environment with plenty of small software programs that act as interfaces and all kinds of small services, as most of you have probably noticed that some part of the functionality is repeated to a greater or lesser extent regardless of the project type.

This library was created completely independently from my professional work as an attempt to build a "base", which can be quickly used in almost any project in order not to repeat again the same codes to achieve functionality like safe (international) type conversion or generic database connection which is easy and most importantly safe to use.
