C# |线程(ThreadStart)构造器

原文:https://www . geeksforgeeks . org/c-sharp-thread start-constructor/

线程(ThreadStart)构造器用于初始化一个线程类的新实例。如果参数值为空，该构造函数将给出 ArgumentNullException 。

语法:

public Thread(ThreadStart start);

这里， ThreadStart 是一个委托，它表示当这个线程开始执行时要调用的一个方法。

以下程序说明了线程(ThreadStart) 构造函数的使用:

例 1:

// C# program to illustrate the
// use of Thread(ThreadStart) 
// constructor with static method
using System;
using System.Threading;

// Driver Class
class GFG {

    // Main Method
    public static void Main()
    {

        // Creating and initializing a thread
        // with Thread(ThreadStart) constructor
        Thread thr = new Thread(new ThreadStart(Job));
        thr.Start();
    }

    // Static method
    public static void Job()
    {
        Console.WriteLine("Number is :");
        for (int z = 0; z < 4; z++) {
            Console.WriteLine(z);
        }
    }
}

输出:

Number is :
0
1
2
3

例 2:

// C# program to illustrate the
// use of Thread(ThreadStart) 
// constructor with Non-static method
using System;
using System.Threading;

class GThread {

    // Non-static method
    public void Job()
    {
        for (int z = 0; z < 3; z++) {
            Console.WriteLine("HELLO...!!");
        }
    }
}

// Driver Class
public class GFG {

    // Main Method
    public static void Main()
    {
        // Creating object of GThread class
        GThread obj = new GThread();

        // Creating and initializing a thread
        // with Thread(ThreadStart) constructor
        Thread thr = new Thread(new ThreadStart(obj.Job));
        thr.Start();
    }
}

输出:

HELLO...!!
HELLO...!!
HELLO...!!
