Thread(ParameterizedThreadStart) Constructor is used to initialize a new instance of the Thread class. It defined a delegate which allows an object to pass to the thread when the thread starts. This constructor gives ArgumentNullException if the parameter of this constructor is null.
Syntax:
public Thread(ParameterizedThreadStart start);
Here, start is a delegate which represents a method to be invoked when this thread begins executing.
Below programs illustrate the use of Thread(ParameterizedThreadStart) Constructor:
Example 1:
// 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();
}
}
Output:
My thread is in progress...!! My thread is in progress...!! My thread is in progress...!!
Example 2:
// 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);
}
}
}
Output:
My thread is in progress...!! 0 1 2
