There is an overloaded constructor and Start on the Thread class that let's
you pass in an object parameter. This object parameter can be whatever you
want it to be, including an array containing other data. The MSDN talks
about it:

I prefer to share data to the thread,
The thread has access to all the public, private & protected data elements
the that the code you're running would have even if it weren't in a
separate thread. For example:
class TestClass
{
protected string m_TestString = "Hello World";
public LaunchThread()
{
Thread th = new Thread(new ParameterizedThreadStart(DoStuff));
th.Start("This is the value to add while in the thread");
}
private void DoStuff(object NewValue)
{
m_TestString = "This is an updated value from a thread: " +
NewValue.ToString();
}
}
Just beware that if multiple threads are updating the same shared variables
you can have some strange issues show up. I suggest you read up (preferably
a book, not just Google) on concurrent program to learn about locks, race
conditions, deadlocks, etc.

You can't pass data to an existing thread like you would a method. To
get
data to a thread there are two classic mechanisms. You can pass all the
data as part of the start up of the thread. Or you can store your data
in
an area accessible to the thread. The thread would then grab it as
needed.

Hi,
How I can pass data to thread or how I can access data from the
thread?
I want to start thread that can modify some data (datarow or dataset
for
example)
any ideas?
