Thread Vs ParameterizedThreadStart - asp.net

Question

I am newbie in .NET. I am using Threads in my project. please check my code below -
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
namespace ConsoleApplication6
{
class Program
{
private void Amadeus(object str)
{
Console.WriteLine(str.ToString());
}
static void Main(string[] args)
{
Program objClass = new Program();
//One way to call Amadeus Method...
Thread objThread = new Thread(objClass.Amadeus);
objThread.Start("Amadeus without ParameterizedThreadStart");
//Other way to call Amadeus Method...
ParameterizedThreadStart objParamThread = new ParameterizedThreadStart(objClass.Amadeus);
Thread ObjThreadParam = new Thread(objParamThread);
ObjThreadParam.Start("Amadeus with ParameterizedThreadStart");
Console.ReadLine();
}
}
}
Can you please tell me what is the difference between above both way as both are doing same work.
Thanks in advance.

Answer 1

Both are same. Read the MSDN documentation.
Visual Basic and C# users can omit the ThreadStart or
ParameterizedThreadStart delegate constructor when creating a thread.
In Visual Basic, use the AddressOf operator when passing your method
to the Thread constructor; for example, Dim t As New Thread(AddressOf
ThreadProc). In C#, simply specify the name of the thread procedure.
The compiler selects the correct delegate constructor.

Answer 2

Yes, both are doing the same thing.
You can create a thread by passing in a function with a ThreadStart (void ThreadStart()) or ParameterisedThreadStart (void ParameterisedThreadStart(Object x)) signature.
The compiler is working out which constructor to call from the type of parameter you are passing into the constructor.
