Question

I have class “Estimation”, this class has a property “EstimationItems” (the type is IList)

public class EstimationItem 
{
    public virtual int Id { get; set; }
    public virtual Product Product { get; set; }
    public virtual int Quantity { get; set; }
    public virtual decimal Price { get; set; }
}

public class Product 
{
    public virtual int Id { get; set; }
    public virtual string Code { get; set; }
    public virtual string Name { get; set; }
}

When I have an instance of “Estimation”, I’d like to know if “EstimationItems” contain a product with the code “MyCode”.

Answer 1

Using this :

List<EstimationItem> items = new List<EstimationItem>();
// Add items

int searchedCode = 1

if(items.Any(i => i.Product.Code == searchedCode))
{
    // Contained
}
