In C#, why can't an anonymous method contain a yield statement?

Question

I thought it would be nice to do something like this (with the lambda doing a yield return):

public IList Find(Expression

        

Answer 1

I would do this:

IList list = GetList();
var fun = expression.Compile();

return list.Where(item => fun.Invoke(item)).ToList();

Of course you need the System.Core.dll referenced from .NET 3.5 for the Linq method. And include:

using System.Linq;
