How I can do this in c#?

The structure is

I have a list int List<int> pieceinfo which I want to get from the List<product>.

Can someone please tell me how I can do this?

I want to write a lambda expression to check if that pieceinfo exists or not.

Model.Find(x => x.Categories.Find(y => y.PieceInfo.Find(z => z.Id == i)))

I want to know how I can check that if every product's categories' pieceinfo has an Id which is also present in list<int> i.

public struct Product
{
    public int Id;
    public string Title;
    public List<Productdetailed> Info;
    public List<ProductCategory> Categories;
}

public struct ProductCategory
{
    public int Id;
    public string Title;
    public bool Has_Image;
    public List<ProductInfo> PieceInfo;
    public int ProdId;
}

/// <summary>
/// Coverage, packing detailed
/// </summary>
public struct ProductInfo
{
    public int Id;
    public string Size;
    public string Packing;
    public string Price;
    public bool PricePerTon;
    public int ProdId;
    public int Cat_Id;
}

public struct Productdetailed
{
    public int Id;
    public string Packaging;
    public string Coverage;
    public int prodId;
}

var allPieces = Model.SelectMany(x => x.Categories).SelectMany(y => y.PieceInfo);
var isPieceExist = allPieces.Any(piece => piece.Id == id);

// or

var findedPiece  = allPieces.FirstOrDefault(piece => piece.Id == id);
