为什么C＃程序运行速度慢而无需调试

Question

I have a short program to print out all Armstrong Numbers from 10 to 999,999.

When I run in debug mode it finishes in under 1 second.

When I run without debugging, two command windows are opened. When the second one finally closes, the output is displayed on the first one (this takes about 12 seconds). However, if I kill the second window from the task manager; the complete output is displayed in the first window.

Also, running the straight .exe files results in the same behavior as running without debugging.

Additionally: When I run the straight exe file I am getting around 100 MB of RAM usage (which as far as I know I shouldn't be for a program this small).

Here's my code:

using System;
public class Program
{
    public static void Main(string[] args)
    {
        Console.WriteLine("ARMSTRONG NUMBERS FOUND FROM 10 THROUGH 999999\n");
        int total_armstrong = 0;
        for (int i = 10; i < 1000000; i++)
        {
            int temp = i;
            int k;
            int total = 0;

            for (k = 0; temp != 0; k++) //runs only 6 times maximum    gives me the exponent to use below
                temp /= 10;
            temp = i;
            while (temp != 0) //runs only 6 times maximum
            {
                total += (int)Math.Pow(temp % 10, k);  //calculates the value of each digit raised to the exponent calculated above
                temp /= 10;
            }
            if (total == i)
            {
                Console.WriteLine(total);
                total_armstrong++;
            }
        }
        Console.WriteLine("\nTOTAL NUMBER OF ARMSTRONG NUMBERS FOUND WAS " + total_armstrong);
    }
}

Answer 1

I ended up re-installing Visual Studio/Windows and the problem resolved itself. In the end the nuclear option always solves the problem.
