示例1: Main
//引入命名空间
using System;
using System.Threading;
using System.Threading.Tasks;
public class Example
{
public static void Main()
{
var rnd = new Random();
int breakIndex = rnd.Next(1, 11);
Nullable<long> lowest = new Nullable<long>();
Console.WriteLine("Will call Break at iteration {0}\n",
breakIndex);
var result = Parallel.For(1, 101, (i, state) => {
Console.WriteLine("Beginning iteration {0}", i);
int delay;
Monitor.Enter(rnd);
delay = rnd.Next(1, 1001);
Monitor.Exit(rnd);
Thread.Sleep(delay);
if (state.ShouldExitCurrentIteration) {
if (state.LowestBreakIteration < i)
return;
}
if (i == breakIndex) {
Console.WriteLine("Break in iteration {0}", i);
state.Break();
if (state.LowestBreakIteration.HasValue)
if (lowest < state.LowestBreakIteration)
lowest = state.LowestBreakIteration;
else
lowest = state.LowestBreakIteration;
}
Console.WriteLine("Completed iteration {0}", i);
});
if (lowest.HasValue)
Console.WriteLine("\nLowest Break Iteration: {0}", lowest);
else
Console.WriteLine("\nNo lowest break iteration.");
}
}输出：
