C # exception handling performance comparison with Java

It is said that C # exception handling is very performance-consuming.

So let's perform a test.

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Diagnostics;namespace ConsoleApplication2{    class Program    {        static void Main(string[] args)        {                        Stopwatch w = new Stopwatch();            w.Start();            int a =10;            for (int i = 0; i <= 1000; i++)            {                Int32.TryParse("a", out a);            }                        w.Stop();            Console.WriteLine(w.ElapsedMilliseconds);            w.Reset();            w.Start();            for (int i = 0; i <= 1000; i++)            {                try                {                    Int32.Parse(null);                }                catch (Exception e)                {                }            }            w.Stop();            Console.WriteLine(w.ElapsedMilliseconds);            Console.Read();        }    }}

The input result is:

0

6780

The gap is big enough. It seems that it is necessary to use tryparse in C!

Let's take a look at java. The same Code:

public class Test {public static void main(String[] args) {long start = System.currentTimeMillis();for(int i=0; i<1000; i++){try{Integer.parseInt(null);}catch(Exception e){}}System.out.println(System.currentTimeMillis()-start);}}

Output result:

2

The gap is big enough! It seems that Jiang is still old and hot. Microsoft has not optimized enough ......
