我知道我可以使用数组 string.Split()

string[] codesarray = codes.Split(',');

但是我如何才能获得产品codes呢?

// the idea I have, but I would not like to have a loop
for (int i = 0; i < codesarray.Length; i++)
{
    detailcollection.Where(x => x.ope_idsku == codesarray[i])
}

我想要像:

detailcollection.Where(x => x.ope_idsku not in (codesarray))
