You can use the LINQ Concat and ToList methods

var allProducts = productCollection1.Concat(productCollection2)
                                .Concat(productCollection3)
                                .ToList();

You can create a new collection and add there:

...
var combineList = new List<KeyWordMetaSchema>();

combineList.AddRange(industryLandingHeades.SubIndustries);
combineList.AddRange(industryLandingHeades.AdditionalKeyword);

If you are going to do it this way (which I am not suggesting, but if you are) you may as well pass the expected size (i.e. capacity) to the `List` constructor (since you know what it is). – mjwills Jan 24 '20 at 10:41

As you are looking Both List into single List.

Just call the main Class or VM:

//TODO: Populate the data in List.

var singleList = new List<IndustryLandingHeader>();

Please try the below :

this.SubIndustries.Concat(this.AdditionalKeyword).ToList()

List.Concat method creates a new sequence of items from both lists without affecting the original list.

Note that Concat method returns IEnumerable<> collection and so we need to apply ToList() over the output of concat method

Here is the link...https://learn.microsoft.com/en-us/dotnet/api/system.linq.enumerable.concat?view=netframework-4.8 In general any collection implementing IEnumerable supports concat method – Ritesh Kulkarni Jan 24 '20 at 12:15
