如何使用System.Threading.Parallel（.Net 4.0）增加并发并行任务(How to increase concurrent parallel tasks with System.Threading.Parallel (.Net 4.0))

我正在尝试新的System.Threading.Parallel方法，如parallel和foreach。

他们似乎很好地工作，但我需要一种方法来增加执行的并发线程数为8（我有一个四核心）。

我知道有一种方法我可以找到你隐藏该死的财产的地方。

I'm experimenting with the new System.Threading.Parallel methods like parallel for and foreach.

They seem to work nicely but I need a way to increase the number of concurrent threads that are executed which are 8 (I have a Quad core).

I know there is a way I just can find the place thy hidden the damn property.

var query = from item in source.AsParallel().WithDegreeOfParallelism(10) where Compute(item) > 42 select item;

在查询执行大量非计算限制工作（如文件I / O）的情况下，指定比机器上的内核数量多的并行度可能会有所帮助。

In cases where a query is performing a significant amount of non-compute-bound work such as File I/O, it might be beneficial to specify a degree of parallelism greater than the number of cores on the machine.
