C＃| Thread(ThreadStart)构造函数

Thread(ThreadStart)构造函数用于初始化Thread类的新实例。如果参数的值为null，则此构造方法将提供ArgumentNullException。

句法：

public Thread(ThreadStart start);

在这里， ThreadStart是一个委托，代表当该线程开始执行时要调用的方法。

下面的程序说明了Thread(ThreadStart)构造函数的用法：

范例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

范例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...!!
