Working with CPU rate limits with C#

I'm trying to reproduce some codes that I have in C++, but when I try to work with CPU control I can't reproduce them without the use [DLL Imports], but I would like to do everything using C# native code, without the need to do any references or imports WIN32 API.

Below the code that I tried to reproduce:

JOBOBJECT_CPU_RATE_CONTROL_INFORMATION info;

// CPU rate control

info.CpuRate = atoi(argv[2]) * 100;

info.ControlFlags = JOB_OBJECT_CPU_RATE_CONTROL_ENABLE | JOB_OBJECT_CPU_RATE_CONTROL_HARD_CAP;

if (!SetInformationJobObject(hJob, JobObjectCpuRateControlInformation, &info, sizeof(info)))

return Error("Failed in setting job information");
