Question

I have this code:

List<string> lineList = new List<string>();

foreach (var line in theFinalList)
{
    if (line.PartDescription != "")
        lineList.Add(line.PartDescription + " " + line.PartNumber + "\n");
    else
        lineList.Add("N/A " + line.PartNumber + "\n");

    //
    //This is what I am trying to fix:
    if (lineList.Contains("FID") || lineList.Contains("EXCLUDE"))
        // REMOVE THE item in the lineList
}

I am trying to go through theFinalList in a foreach loop and add each line to a new list called lineList.
Once added, I want to remove any entries from that list that contain the text “FID” or “EXCLUDE”.

I am having trouble removing the entry, can someone help me?

Answer 1

why add them when you want to remove them right after:

lineList = theFinalList.Select( line => 
{
    if (line.PartDescription != "")
        return line.PartDescription + " " + line.PartNumber + "\n";
    else
        return "N/A " + line.PartNumber + "\n";
})
.Where(x => !(x.Contains("FID") || x.Contains("EXCLUDE")))
.ToList();
