Question

In lua, one can very easily create a table and add functions to it.

How do I do that in C#? My first idea was to use a List of delegates and fill the list with anonymous functions, but I can’t get the syntax right.

public class PlanItem
{
    public string Name { get; set; }   
    public List<BusinessRule> Rules;
}

public delegate bool BusinessRule(PlanItem item);

[Test]
public void TestIt()
{
    PlanItem item = new PlanItem();
    item.Rules.Add(
        BusinessRule(PlanItem item)
        {
            return !string.IsNullOrEmpty(item.Name);
        }
    );

   foreach(BusinessRule rule in item.Rules)
   {
     if(!rule(item))
         // write uh-oh
   }
}

Answer 1

This should do the trick:

 item.Rules.Add((planItem) => 
 { 
     return !string.IsNullOrEmpty(planItem.Name); 
 });
