No ParameterizedThreadStart? No problem.

  • Article

The .NET Compact Framework is a subset of the .NET Framework.  As such, there are features and functionality that exist in the .NET Framework that do not in the .NET Compact Framework.  One such feature is ParameterizedThreadStart.

If your ThreadStart delegate needs data provided by the caller you can create a wrapper object for the method.  To get the data to the delegate, you pass the it as arguments to your wrapper object's constructor.  The delegate then accesses the data as member variables when performing its work.

By creating an instance of the above class, you can pass your desired iterations to the Worker method. 

// create the wrapper object, passing in the desired number of iterationsThreadStartDelegateWrapper wrapper = new ThreadStartDelegateWrapper(15);// create and start the threadThreadStart ts = new ThreadStart(wrapper.Worker);Thread t = new Thread(ts);t.Start();
For clarity, the above example was shown on multiple lines.  I have often written the above on a single line.

new Thread(new ThreadStart(new ThreadStartDelegateWrapper(15).Worker)).Start();
Enjoy!
