How to read native process memory in C# without creating Garbage Collector allocations:
CSHARP
public static unsafe T ReadMemory<T>(IntPtr hProcess, IntPtr address) where T : unmanaged {
T val = default;
ReadProcessMemory(hProcess, address, &val, sizeof(T), out _);
return val;
}
// Reading arrays with stackalloc Span
Span<byte> buffer = stackalloc byte[1024];
ReadProcessMemory(hProcess, address, buffer, out int bytesRead);
ReadOnlySpan<float> matrix = MemoryMarshal.Cast<byte, float>(buffer);Zero GC gen-0 allocations, execution latency matches C++!
