【问题描述】:
我正在开发我的多线程密码破解程序,只有数字。它必须显示找到密码已经过去了多少时间。我使用Stopwatch 找到它,但在函数中Stopwatch 不起作用。这是我的代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Diagnostics;
using System.Threading;
namespace ConsoleApplication4
{
class Program
{
static void Main(string[] args)
{
int psw = 14995399;
Stopwatch time = new Stopwatch();
Thread Thread1 = new Thread(islem1);
Thread Thread2 = new Thread(islem2);
Thread Thread3 = new Thread(islem3);
Thread Thread4 = new Thread(islem4);
time.Start();
Thread1.Start();
Thread2.Start();
Thread3.Start();
Thread4.Start();
Thread.Sleep(1000);
time.Stop();
System.Console.WriteLine("Time elapsed: {0}", time.Elapsed);
Console.ReadKey();
}
static void islem1()
{
for (int i = 00000000; i < 25000000; i++)
{
int psw = 14995399;
if (i == psw)
{
System.Console.WriteLine("Şifre=" + i);
time.Stop();
Console.WriteLine("Time elapsed: {0}", time.Elapsed);
Console.ReadKey();
}
}
}
static void islem2()
{
for (int i = 25000000; i < 50000000; i++)
{
int psw = 14995399;
if (i == psw)
{
System.Console.WriteLine("Şifre=" + i);
time.Stop();
Console.WriteLine("Time elapsed: {0}", time.Elapsed);
Console.ReadKey();
}
}
}
static void islem3()
{
for (int i = 50000000; i < 75000000; i++)
{
int psw = 14995399;
if (i == psw)
{
System.Console.WriteLine("Şifre=" + i);
time.Stop();
Console.WriteLine("Time elapsed: {0}", time.Elapsed);
Console.ReadKey();
}
}
}
static void islem4()
{
for (int i = 75000000; i < 100000000; i++)
{
int psw = 14995399;
if (i == psw)
{
System.Console.WriteLine("Şifre=" + i);
time.Stop();
Console.WriteLine("Time elapsed: {0}", time.Elapsed);
Console.ReadKey();
}
}
}
}
}
【问题讨论】:
-
在每个线程函数中创建一个单独的
Stopwatch。不要创建一个并在线程之间共享它。 -
这不是“不起作用”,而是“无法编译”。这是一个巨大的差异。
