Question

I have the code below

RssFeedReader rss = (RssFeedReader)this.ParentToolPane.SelectedWebPart;

My problem is only at run time do I know if ‘this.ParentToolPane.SelectedWebPart’ is of type RssFeedReader or of type ‘RssCountry’

How would I check the object type and cast it appropriatley?

Many Thanks,

You can do this:

if (this.ParentToolPane.SelectedWebPart is RssFeedReader)
    //...

To check if it is of a certain type. Alternatively, you can use ‘as’ to use it as a type, and it will be null if it was not of that type.

RssFeedReader reader = this.ParentToolPane.SelectedWebPart as RssFeedReader;
if (reader != null)
{
    //...
}
