C# |线程(ParameterizedThreadStart)构造器

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

Thread(parameterzedsthreadstart)构造函数用于初始化 Thread 类的一个新实例。它定义了一个委托，该委托允许对象在线程启动时传递给线程。如果该构造函数的参数为空，则该构造函数给出 ArgumentNullException 。

语法:

public Thread(ParameterizedThreadStart start);

这里， start 是一个代表当这个线程开始执行时要调用的方法的委托。 下面的程序说明了线程的使用(参数化线程启动)构造函数: 示例 1:

c sharp . c sharp . c sharp . c sharp

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

public class MYTHREAD {

    // Non-static method
    public void Job()
    {
        for (int z = 0; z < 3; z++) {

            Console.WriteLine("My thread is "+
                          "in progress...!!");
        }
    }
}

// Driver Class
public class GFG {

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

        // Creating a thread which
        // calls a parameterized instance method
        Thread thr = new Thread(obj.Job);
        thr.Start();
    }
}

输出:

My thread is in progress...!!
My thread is in progress...!!
My thread is in progress...!!

例 2:

c sharp . c sharp . c sharp . c sharp

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

// Driver Class
public class GFG {

    // Main Method
    public static void Main()
    {
        // Creating a thread which calls
        // a parameterized static-method
        Thread thr = new Thread(Job);
        thr.Start();
    }

    // Static method
    public static void Job()
    {
        Console.WriteLine("My thread is"+
                    " in progress...!!");

        for (int z = 0; z < 3; z++) {
            Console.WriteLine(z);
        }
    }
}

输出:

My thread is in progress...!!
