Question

I am trying to create a class that inherits from SPListItem. When I try to compile it throws the error:

The type
‘Microsoft.SharePoint.SPListItem’ has
no constructors defined

Here is my code:

public class MySPListItem : SPListItem
{
    public string ItemUrl {get;set;}
}

Is there anyway I can inherit from SPListItem?

Answer 1

As svick has pointed out, the documentation states that there are no public or protected constructors which means you won’t be able to inherit from this class.

I do wonder though, if you’re inheriting so that you can extend this class, you might be best off writing some extension methods.

This might be a viable option if that’s what you’re intending to do, extend the class.
