This just a simple code snippet for a practical use, especially batch job sort of things.

public static class Extensions
{
    public static void ParallelForEach<T>(this List<T> list, Action<T> action)
    {
        list.ForEach(item => new Thread(() => action(item)).Start());
    }
}
`</pre>

This can be used like:

<pre>`var inputs = new List&lt;string&gt;()
                 {
                     "abc.csv",
                     "xyz.csv",
                 };

inputs.ParallelForEach(path =&gt; ProcessBatchFile(path));

// Assuming a method, ProcessBatchFile, is already defined.
