Hello,

I have a Generic.List(Of MyClass)

MyClass has two properties: ID and Value, both strings.

I want to look for the item, in my Generic.List(Of MyClass), with a
given ID.

How can I do this?

Thanks,

Miguel

By looping through the list and looking for the id.

If you would use a Dictionary<sring, MyClass> instead, and using the ID
as key, you would be able to get the item directly.

Its also possible to implement a class that derives from List<MyClass> and
implement a ContainsKey method.
In this method, you can use the Enumerator to loop through the data

Yes, that would be the prefered way :-)
