法律學C# 程式建立執行緒池
對於一個執行緒池，建立超過兩個函式和佇列方法以供執行。
首先，建立一個類似於下列內容的方法－
public void one(object o) {
for (int i = 0; i <= 3; i++) {
Console.WriteLine("One executed");
}
}同樣地，建立更多的方法，然後使用 ThreadPool.QueueUserWorkItem為執行排隊這些方法－
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
你可以嘗試執行以下 C# 程式碼來建立執行緒池。
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();
}
}輸出
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 Two executed Three executed Three executed Two executed One executed Three executed Two executed Three executed One executed One executed One executed
