Can't get a Request Token or Access Token with OAuthBase (C#)

[GoogleCodeExporter]

(C#)  OAuthBase removes parameters that start with oauth_ in the 
GetQueryParameters method.

In GenerateSignatureBase() it adds the parameters needed for a protected 
resource request back.  It does not add other oauth parameters needed to get a 
Request Token or Access Token.  Specifically, it does not add oauth_verifier or 
oauth_callback.

As other libraries include these in the signature base (per the spec), the 
signature produced by OAuthBase for Access Token and Request Token requests do 
not agree with other libraries.

I solved this problem by adding these parameters to the various signature 
methods (see attached).

Please provide any additional information below.

I had the same problem with the oauth_verifier. The problem is a bug in the 
method GetQueryParameters: This condition discards every parameter that begins 
with oauth_:
if (!string.IsNullOrEmpty(s) && !s.StartsWith(OAuthParameterPrefix))
so there are never parameters returned.

This should work correct:
if (!string.IsNullOrEmpty(s) && s.StartsWith(OAuthParameterPrefix))
