New to LINQ and trying to figure out how to exclude an item from a list. I have a list of names and their position level. Which looks like
Name ID Level
aaa 123 0
bbb 122 1
ccc 222 2
ddd 223 3
What I'm trying to do is figure out a way to exclude the record with the highest level. I'm refactoring some code that was using a for loop to check for this and I'm having a hard time figuring out how to mirror that.
Exact structure of your types is not clear, but something like this:
list.OrderBy(x=>x.Level).Take(list.Count-1) //where x is an Item (Raw) from he list
should work foryou.
if you might have multiple MAX values just use Distinct (see examples in documentation how to use it)
if you might have multiple repetitive values in collection (including non MAX values), you might do
list.OrderByDescending(x => x.Level);
var max = list.First();
var result = list.SkipWhile(x=>x == max);
ToList()if you intend to siply iterate over result.The simplest way is:
var max = list
.Max(l => l.Level);
var listWithoutMax = list
.Where(l => l.Level != max);
This small code snippet should work fine:
Int32 max = list.Max(x => x.Level);
List<MyObject> newList = list.Where(x => x.Level != max).ToList();
and, if your list contains more than one element with the maximum level value, will ensure that all of them will be removed from it.
You can use RemoveAll():
var result = list.RemoveAll(x => x.Level == list.Max(s => s.Level));
Levelvalues different and unique?
