Analong of Concurrency::combinable<T> in C#?

Is there any way of duplicating the functionality found within the combinable data structure within C++ in C#?

In C++ I could do something along the lines of:

Concurrency::combinable<CustomData> c;
Concurrency::parallel_for(0, size, [&](int i)
{
    CustomData cd = some_operation(i);
    c.local() += cd;
});
c.combine([](CustomData a, CustomData b) { return a + b; });

Where CustomData is some arbitrary data that has a well def开发者_如何学编程ined addition operator.

Any help would be much appreciated!
