Missing libraries for using oAuth2 with google drive on .Net
I am trying to get the example code working in VB .Net I imported the example Oauth.
The example on the google Drive website is here from where I imported the sample code into VB.Net https://developers.google.com/drive/credentials
It has these two references
Imports Google.Apis.Oauth2.v2
Imports Google.Apis.Oauth2.v2.Data
I cannot find the libraries in the downloads for the libraries above and I getting errors here in the code:
Dim credentials As IAuthorizationState = ExchangeCode(authorizationCode)
Dim userInfo As Userinfo = GetUserInfo(credentials)
Dim userId As [String] = userInfo.Id
emailAddress = userInfo.Email
As userInfo is not defined anywhere. Is it in the missing .dll files?
And
Dim userInfoService As New Oauth2Service(GetAuthenticatorFromState(credentials))
Dim userInfo As Userinfo = Nothing
Oauth2Service cannot be found?
What am I doing wrong here?
The library you are looking for has a DLL reference, but you have to extract it twice.
Once you extract the initial download (http://code.google.com/p/google-api-dotnet-client/wiki/APIs#Google_OAuth2_API), there should be a few zip files in that folder, along with "Lib" and "dependencies" one of them should be:
google-oauth2-v2-rev38-csharp-1.3.0-beta-src.zip or google-oauth2-v2-rev38-csharp-1.3.0-beta-bin.zip 
Extract the zip file that has the binary, and the Google.Apis.Oauth2.v2 dll should be there for you to import into the project.
This should fix the error. It's not obvious, it took me a bit to figure out the situation. This is basically how all the APIs that you download for the .Net library are structured.
I hope this helps.
Oauth2是一项独立服务，具有其他二进制文件，可从http://code.google.com/p/google-api-dotnet-client/wiki/APIs#Google_OAuth2_API下载
