read text file and writing to a list

Is their a way to split a text file in multiple places all at once and save to a list?

I was able to do the split in one place and write to a list like this:

var incomplete = File
            .ReadAllLines(path)
            .Select(a => a.Split(new[] { '|' }, StringSplitOptions.None)[5].Trim())
            .ToList();

I would like to split in four locations and then write to a list.

var mnbrs = File
            .ReadAllLines(path)
            .Select(a => a.Split('|')[2].Trim())
            .Select(b => b.Split('|')[5].Trim())
            .Select(c => c.Split('|')[6].Trim())
            .Select(d => d.Split('|')[11].Trim())
            .ToList();

this gives me error index was outside of bounds of array.

Any help is appreciated. Am also open to split and read filing in a different manner as well. I just would like to avoid reading file split once then to list then reading agian and splitting again and doing it four times.

You want to do it in two steps. First split, then select the individual columns:

File
    .ReadAllLines(path)
    .Select(a => a.Split(new[] { '|' }, StringSplitOptions.None))
    .Select(a => new {
        Column1 = a[2].Trim(),
        Column2 = a[5].Trim(),
        Column3 = a[6].Trim(),
        Column4 = a[11].Trim()
    })
    .ToList();
