在Linq Where子句中压缩多个OR

Question

Let's say I have this code:

myList = myList.Where(x => x[0] > .0005 || x[1] > .0005 || x[2] > .0005).ToList();

There has to be a way to just do this over an enumerable range?

I was thinking something along the lines of

myList = myList.EnumerableRange(0, x.Count).Where(i => x[i] > .0005)

But this doesn't seem to be working. What am I missing/Is there a better way?

Answer 1

You can use the LINQ method Any for that.

myList = myList.Where(x => x.Any(d => d > .0005)).ToList();

I am assuming you are looking to check all the items in x . Otherwise you will have to use the LINQ extensions Take and Skip to get a slice of the array. Also assuming that x is an IEnumerable<T> . Note that, if you expect x to be null you will have to handle it

Answer 2

您仍然需要执行-或等效操作-将多个Where子句有效地与在一起：

yList = myList.Where(x => Enumerable.range(0, x.Count).Any(i => x[i] > .0005)).ToList();
