The default for KeyValuePair

I have an object of the type IEnumerable> keyValueList, I am using

var getResult= keyValueList.SingleOrDefault();
 if(getResult==/*default */)
 {
 }
 else
 {
 }

How can I check whether getResult is the default, in case I can't find the correct element?

I can't check whether it is null or not, because KeyValuePair is a struct.

Try this:

if (getResult.Equals(new KeyValuePair()))

or this:

if (getResult.Equals(default(KeyValuePair)))
