i like to set timer for calculating execution time in c# for particular process in my execution. how can i do this

Calculate the execution timeThe difference between the end time and start time is the execution time. Get the execution time by subtracting the start time from the end time.
There are two ways to measure elapsed execution time in Java either by using System. currentTimeinMillis()or by using System. nanoTime(). These two methods can be used to measure elapsed or execution time between two method calls or events in Java.
If milliseconds then in Visual Studio 2019 you can see the time between two breakpoints under Diagnostic Tools -> Events -> Duration (opens automatically in Debug mode, or use Ctrl + Alt + F2 ). Some notes: Make sure to measure performance of the Release configuration. Debug build performance is meaningless.
Python timeit module is often used to measure the execution time of small code snippets. We can also use the timeit() function, which executes an anonymous function with a number of executions. It temporarily turns off garbage collection while calculating the time of execution.
You don't generally use a timer for this - you use a Stopwatch.
Stopwatch sw = Stopwatch.StartNew();
// Do work
sw.Stop();
TimeSpan elapsedTime = sw.Elapsed;
If you're performing benchmarking of something relatively fast, it's worth doing it many, many times so that the time taken is significant (I usually go for 5-30 seconds). That's not always feasible, admittedly - and there are many more subtleties which affect real world performance (such as cache hits/misses) which micro-benchmarking often misses out on.
Basically, be careful - but Stopwatch is probably the best starting point in many cases.

You can use System.Diagnostics.Stopwatch to do what you want.
