RSCG – Dolly
 
 

Clone objects with ease.

This is how you can use Dolly .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net9.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Dolly" Version="0.0.7">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
using CloneData;

Console.WriteLine("Hello, World!");
Person p = new ();
p.FirstName = "Andrei";
p.LastName = "Ignat";
p.Age = 54;
var p1=p.DeepClone();
Console.WriteLine(p1.Name());

namespace CloneData;
[Dolly.Clonable]
public partial class Person
{
    public string FirstName { get; set; } = "";
    public string LastName { get; set; } = "";
    [Dolly.CloneIgnore]
    public int Age { get; set; }
    public string Name() => $"{FirstName} {LastName}";

    public Person[] Childs { get; set; } = [];
}

The code that is generated is

using System;

The resolution of the <b>GetTickCount</b> function is not affected by adjustments made by the <a href="https://docs.microsoft.com/windows/desktop/api/sysinfoapi/nf-sysinfoapi-getsystemtimeadjustment">GetSystemTimeAdjustment</a> function. The elapsed time is stored as a <b>DWORD</b> value. Therefore, the time will wrap around to zero if the system is run continuously for 49.7 days. To avoid this problem, use the <a href="https://docs.microsoft.com/windows/desktop/api/sysinfoapi/nf-sysinfoapi-gettickcount64">GetTickCount64</a> function. Otherwise, check for an overflow condition when comparing times. If you need a higher resolution timer, use a <a href="https://docs.microsoft.com/windows/desktop/Multimedia/multimedia-timers">multimedia timer</a> or a <a href="https://docs.microsoft.com/windows/desktop/winmsg/about-timers">high-resolution timer</a>. To obtain the time elapsed since the computer was started, retrieve the System Up Time counter in the performance data in the registry key <b>HKEY_PERFORMANCE_DATA</b>. The value returned is an 8-byte value. For more information, see <a href="https://docs.microsoft.com/windows/desktop/PerfCtrs/performance-counters-portal">Performance Counters</a>. To obtain the time the system has spent in the working state since it was started, use the <a href="https://docs.microsoft.com/windows/desktop/api/realtimeapiset/nf-realtimeapiset-queryunbiasedinterrupttime">QueryUnbiasedInterruptTime</a> function. <div class="alert"><b>Note</b>  The <a href="https://docs.microsoft.com/windows/desktop/api/realtimeapiset/nf-realtimeapiset-queryunbiasedinterrupttime">QueryUnbiasedInterruptTime</a> function produces different results on debug ("checked") builds of Windows, because the interrupt-time count and tick count are advanced by approximately 49 days.

Generating class to access easy the embedded resource

This is how you can use Datacute.EmbeddedResourcePropertyGenerator .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  
  <ItemGroup>
    <EmbeddedResource Include="TestData\Countries.txt" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Datacute.EmbeddedResourcePropertyGenerator" Version="1.0.0" >
    </PackageReference>
  </ItemGroup>
	<PropertyGroup>
		<AdditionalFileItemNames>$(AdditionalFileItemNames);EmbeddedResource</AdditionalFileItemNames>
	</PropertyGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
using EmbedDemo;

Console.WriteLine("Hello, World!");

var data= TestData.Countries;

Console.WriteLine(data);

using Datacute.EmbeddedResourcePropertyGenerator;
namespace EmbedDemo;
[EmbeddedResourceProperties(".txt", "TestData")]
public static partial class TestData;

USA
Germany
France
Romania
Italy
