代码试图找到ServiceAccountCredential.cs文件，同时使用OAUTH 2.0访问谷歌分析

我试图使用OAUTH 2.0认证访问ga:visits和ga:transactions的谷歌分析数据。我遵循了以下步骤:

1. 在https://code.google.com/apis/console/网站上启用了Google Analytics API。另外，创建了一个客户端ID并保存了。p12密钥
2. 生成的电子邮件id在Analytics网站上提供Read和Analyze访问权限。
我创建了一个Windows窗体应用程序，并使用package命令下载了NuGet包:—Install-Package google . api . analytics .v3所有引用包括Google.Apis,Google.Apis. analytics .v3,Google.Apis. auth,Google.Apis. auth . platformservices,Google.Apis. core,Google.Apis。平台服务被添加到项目

此外，在访问数据时遇到错误:-

查找来源c:'code'google.com'google-api-dotnet-client'default'Tools'Google.Apis.Release'bin'Debug'test'default'Src'GoogleApis.Auth.DotNet4'OAuth2'ServiceAccountCredential.cs

，同时运行以下代码行:

var credential = new ServiceAccountCredential(new     ServiceAccountCredential.Initializer(serviceAccountEmail)         
 {    
    Scopes = new[] { AnalyticsService.Scope.AnalyticsReadonly }    
 }.FromCertificate(cert));   

你能帮我解决这个错误吗?请查看下面使用的代码:-
