c# - Determining casting of an object -

-

i have code below

rssfeedreader rss = (rssfeedreader)this.parenttoolpane.selectedwebpart;

my problem @ run time know if 'this.parenttoolpane.selectedwebpart' of type rssfeedreader or of type 'rsscountry'

how check object type , cast appropriatley?

many thanks,

you can this:

if (this.parenttoolpane.selectedwebpart rssfeedreader)     //...

to check if of type. alternatively, can use 'as' use type, , null if not of type.

rssfeedreader reader = this.parenttoolpane.selectedwebpart rssfeedreader; if (reader != null) {     //... }
