C#程序创建线程池

对于线程池，创建两个以上的函数并排队执行方法。

首先，创建类似的方法-

public void one(object o) {
   for (int i = 0; i <= 3; i++) {
      Console.WriteLine("One executed");
   }
}

以相同的方式，创建更多方法，然后使用 ThreadPool.QueueUserWorkItem将方法排队以执行-

Demo d = new Demo();
for (int i = 0; i < 3; i++) {
   ThreadPool.QueueUserWorkItem(new WaitCallback(d.one));
   ThreadPool.QueueUserWorkItem(new WaitCallback(d.two));
   ThreadPool.QueueUserWorkItem(new WaitCallback(d.three));
}

示例

您可以尝试运行以下C#代码来创建线程池。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
class Demo {
   public void one(object o) {
      for (int i = 0; i <= 3; i++) {
         Console.WriteLine("One executed");
      }
   }
   public void two(object o) {
      for (int i = 0; i <= 3; i++) {
         Console.WriteLine("Two executed");
      }
   }
   public void three(object o) {
      for (int i = 0; i <= 3; i++) {
         Console.WriteLine("Three executed");
      }
   }
   static void Main() {
      Demo d = new Demo();
      for (int i = 0; i < 3; i++) {
         ThreadPool.QueueUserWorkItem(new WaitCallback(d.one));
         ThreadPool.QueueUserWorkItem(new WaitCallback(d.two));
         ThreadPool.QueueUserWorkItem(new WaitCallback(d.three));
      }
      Console.Read();
   }
}

输出结果

Two executed
Two executed
Two executed
Two executed
Two executed
Two executed
Two executed
One executed
One executed
One executed
One executed
One executed
Two executed
