Which Google APIs client version do you use?
I recommend you by the way to open a thread in SO using our 
google-api-dotnet-client tag first (as recommended in the website), and only if 
we will find that there is actually a bug, we will open a thread.

Please update this post with the SO thread, and we will take it from there.
Thanks!

Attaching the fiddler request and response might help as well :)

i have opened a thread on SO with  google-api-dotnet-client tag
and  i am mentioning below  which Google APi i i am using..

i am using 
            IDE       :     VS2012  
            Framework :     4.0
            Google API:     Youtube Data V3
            Authentication: Outh 2.0

for set watermark request it gives  response: Value cannot be null Parameter 
name: baseUri
and for unset watermark it gives --Error 503-backend error..

my unset watermark code is :

var unsetrequest = youtubeService.Watermarks.Unset("UCyAn2aVZWNAugdlckOJKG5A");
        // searchListRequest.Q = txtSearchKeyword.Text;

        var searchListResponse = unsetrequest.Execute();

    }
