How to count await method execution time

Question

I am working on a dot net core project. In which I have to count how much had taken by my await method while executing.

[HttpPost]
public async Task<bool> InsertIntoDatabase([Frombody] StudentModel objStu) {
//For Each method and other stuff
  await DoInsert(Fiels Details);
}

I am calling this method in Ajax. So after successful execution of code, I want to return the number of times in minutes taken by the method.

This insertion process contains 500+ records. So, I am interested to calculate the time

Answer 1

Why not return a custom object in your task with the time and the result?

private async Task<MyClass> GetResult()
{}

public class MyClass
{
    public bool  Success { get; set; }
    public long TimeInSeconds { get; set; }
}

I would highly recommend checking out MiniProfiler. It's extremely easy to setup!

1. Install MiniProfiler via Nuget
2. Add the MiniProfiler tag helper to your _Layout.cshtml
3. Add the MiniProfiler tag (<mini-profiler />) to your HTML (I put mine in Layout.cshtml as well)
4. Add to services in Startup.cs:

services.AddMiniProfiler(options =>
{
    options.RouteBasePath = "/profiler";
    options.SqlFormatter = new SqlServerFormatter();
});

5. Add this AFTER calling app.UseStaticFiles():

if (env.IsDevelopment())
{
     app.UseMiniProfiler();
}

Now MiniProfiler is ready to go and will only appear in development (step 5). To profile some code do:

using (MiniProfiler.Current.Step("This Will be the label displayed on the front end"))
{
    //code you want to profile
}

Now run your code and voila! MiniProfiler will put a very small table on your page (I THINK it defaults top left). Each row is the elapsed of the request (works with AJAX too!).
