将循环更改为Parallel.For循环

Question

我可以改变我的循环

for (int i = 0; i < something; i++)

至:

Parallel.For(0, something, i =>

但是如何用这个循环做到这一点？:

for (i = 3; i <= something / 2; i = i + 2)

谢谢你的回答.

Answer 1

以来

for (int i = 3; i <= something / 2; i = i + 2)
{
    ...
}

可以改写成

for (int k = 1; k < (something + 2) / 4; ++k)
{
    int i = 1 + 2 * k;
    ...
}

你可以把

Parallel.For(1, (something + 2) / 4, k =>
{
    int i = 1 + 2 * k; 
    ... 
});
