Question

运行时环境：.net core 2.2，.net framework 4.6.1的相同问题

在尝试为Google Assistant SDK的C＃创建gRPC绑定时，在EmbeddedAssistant.g.cs中出现编译时错误 “无法从System.Type转换为Google.Type”

可供下载的项目

我在Google.Protobuf上也遇到了错误

“类型”是一个名称空间，但其使用方式类似于类型。

详细信息

我关注了instructions to integrate google assistant for C# (Other languages: gRPC)

clone Google APIs on local disk
我下载了 Protoc Compiler latest release
按照说明生成EmbeddedAssistant.g.cs文件
更早之前，Google.Protobuf.Collections和Google.Protobuf.Reflection不可用引发了错误，因此我从##的链接下载了 protobuf-csharp-3.9.0.zip 2，将Google.Protobuf文件夹复制到我的项目文件夹中，该错误消失了。
对于Google.API和Google.Type错误，我遵循此 Stackoverflow article 并已解决。

编译输出，错误是：

          }));
    }

EmbeddedAssistant.g.cs 101至116行的已编译输出时出现编译器错误

Google.Protobuf ReflectionUtil.cs上类型上的

和编译器错误类型是一个名称空间，但使用起来就像类型。

 internal static readonly Type[] EmptyTypes = new Type[0];

        /// <summary>
        /// Creates a delegate which will cast the argument to the type that declares the method,
        /// call the method on it, then convert the result to object.
        /// </summary>
        /// <param name="method">The method to create a delegate for, which must be declared in an IMessage
        /// implementation.</param>
        internal static Func<IMessage, object> CreateFuncIMessageObject(MethodInfo method) =>
            GetReflectionHelper(method.DeclaringType, method.ReturnType).CreateFuncIMessageObject(method);

C# Project Structure. Files under Google folder /API , /Assistant and /Type were generated by Protoc 3.9.0 compiler

问题已解决

我使用了此链接 https://github.com/grpc/grpc/blob/master/src/csharp/BUILD-INTEGRATION.md

基本上从googleapis添加了最低必需的.proto文件，以使Google助手正常工作。附加图片

Screenshot of what project looks like

然后添加了 Grpc和Grpc.Tools nuget软件包，并按照上述文章中的说明更改.csproj并进行了构建。

我刚刚在csproj中添加了以下内容

$this->date_filed_to_current_date = $this->cst_to_cmt + $this->cmt_to_current_date;

它生成了图像中显示的输出

构建失败，但是生成了CS文件。提取生成的CS文件，将它们添加到您的真实项目中，然后添加 Google.Protobuf nuget包，进行构建，一切就很好了。

C＃的Protoc 3.9编译输出失败
