在c#中检索键小于指定值的元素集合

Question

I have a dictionary which is
ConcurrentDictionary<uint, Mensaje> mensajesEnviados = new ConcurrentDictionary<uint, Mensaje>();

I want to retrieve all the objects Mensaje whose key value is less than a certain value, to iterate on them. How should I do that?

Thanks in advance!

Answer 1

Try this:

var value = 42u; //your certain value
foreach (var m in mensajesEnviados.Where(kvp => kvp.Key < value).Select(kvp => kvp.Value))
{
}
