【问题描述】：
我对 Google Analytics API .NET 有疑问。 在线通过 api 连接到 GA 时
var certificate = new X509Certificate2(pathToPrivateKey, passToPrivateKey, X509KeyStorageFlags.Exportable);
ServiceAccountCredential credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(serviceAccountEmailAddress)
{
Scopes = scopes
}.FromCertificate(certificate));
它给出以下错误
Message=The type initializer for 'Google.Apis.Http.ConfigurableMessageHandler' threw an exception.
Source=Google.Apis.Core
TypeName=Google.Apis.Http.ConfigurableMessageHandler

我在 Windows 7 上尝试了相同的代码，它可以工作。
我不知道出了什么问题。
任何想法？
【问题讨论】：
-
检查 GAC 中是否没有多余的 dll 浮动或将引用 dll 设置为复制本地。
-
所有外部 dll - 复制本地：是的，我认为问题可能出在 C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0 我没有 System.Net .Http.dll 所以我使用命令 gacuitl /i System.Net.Http.dll 添加它。该 dll 由 HttpClientFactory.cs 使用。
-
@DalmTo 我检查了第二台机器 Windows Server 2003 R2，这次在运行时 VS 询问我：c:\code\google.com\google-api-dotnet-client\default\Tools\ Google.Apis.Release\bin\Debug\test\default\Src\GoogleApis.Core\Apis\Http\HttpClientFactory.cs
-
@DalmTo 在 Windows Server 2008 R2 上检查 - 效果很好。
