Generating WinAPI code in C#

 

This is how you can use Microsoft.Windows.CsWin32 .

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="Microsoft.Windows.CsWin32" Version="0.3.106">
      <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

Console.WriteLine("Hello, World!" + Windows.Win32.PInvoke.GetTickCount());

GetTickCount

		/// <remarks>
		/// <para>The resolution of the <b>GetTickCount</b> function is limited to the resolution of the system timer, which is typically in the range of  10 milliseconds to 16 milliseconds. 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. This helps to identify bugs that might not occur until the system has been running for a long time. The checked build is available to MSDN subscribers through the <a href="https://msdn.microsoft.com/default.aspx">Microsoft Developer Network (MSDN)</a> Web site.</div> <div> </div></para>
