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...!!
