MethodImplOptions.AggressiveInlining: Use this selection inform the JIT compiler that the tactic needs to be inlined.MethodImplOptions.NoInlining: Use this selection to specify that the tactic shouldn’t be inlined.MethodImplOptions.NoOptimization: Use this selection if you don’t want the tactic to be optimized.MethodImplOptions.Synchronized: Use this selection to tell the JIT compiler that the tactic needs to be executed by just one thread at a time.
Benchmarking methodology inlining efficiency in C#
It goes with out saying that you must by no means deploy an inlined methodology with out first measuring the outcomes. So, let’s do this. We’ll benchmark the efficiency of a computation with and with out inlining.
Take into account the next class named Utility that incorporates two strategies, NoInliningDemo and AggressiveInliningDemo. Each of those strategies carry out the exact same computation, which is calculating the sq. roots of a collection of integers. The supply code of the 2 strategies is equivalent. The one distinction is how they’re executed — one methodology is inlined, whereas the opposite is just not.
public static class Utility
{
[MethodImpl(MethodImplOptions.NoInlining)]
public static void NoInliningDemo(int[] arr)
{
for (int i = 0; i
The logic of the 2 strategies is simple. They settle for an integer array as a parameter and generate the sq. root of every integer within the array. The sq. root worth is discarded, i.e., it’s neither processed nor returned from both of those strategies.
The next code snippet reveals the MethodPerformanceBenchmark class that’s used to benchmark the efficiency of the 2 strategies outlined within the Utility class. Word the utilization of the Benchmark attribute. This attribute, when used on a technique, signifies that the tactic needs to be benchmarked.

public class MethodPerformanceBenchmark
{
int[] integerArray = { 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 };
int NumberOfItems = 1000;

To run the benchmark, execute the next assertion on the Visible Studio Command Immediate.
dotnet run -p Method_Impl_Example.csproj -c Launch
