Using ParameterizedThreadStart is bad, because it forces you into type case.
This is much better way of passing parameters into a thread and solving any similar problems — creating a thread wrapper which would automatically pass the instance of the class via "this".

Code sample is very simple:

Good answer, my 5.
It is a shame that it is not C# 4.0. The new Task Parallel Library is a really great tool.

Thank you Kim.
Task Parallel library is not quite related to the topic. Tasks are done on top of threads, did you know that?
In many cases we need threads, not tasks.

Solution 1

You have to change

update(DataTable dt)
{
}

To

update(object data)
{
  DataTable dt = (DataTable) data;
}

See constructor for Thread[^] and code example under ParameterizedThreadStart [^].

You resolve the problem, but I can vote only 4.
Not everything is good in Microsoft! The ParameterizedThreadStart sample code you reference is pretty bad, and the hole idea of ParameterizedThreadStart is really stupid. I advice to never use it -- it is never useful.

In my solution I show how to do it right. It may look surprising, but it's easier, safer and more universal at the same time. Please see.
