我如何生成饰有属性的C＃类.proto文件？ [英] How do I generate a .proto file from a C# class decorated with attributes?
问题描述
试图绕过谷歌protobuf的脑海里。我发现在C＃中一些实现protobuf的，但他们似乎缺少一个特征：从装饰的属性现有的C＃类自动生成.proto文件的能力。
我想做的事情，而不是从自动生成的C＃类会从.proto文件中这样说的原因是因为我已经在我的项目中定义的C＃类，我不希望重复他们只是为了满足protobuf的
有谁曾经遇到过这样的情况？
更新
这是可能的，只是装点一个C＃类，而不是使用一个.proto文件中使用protobuf的？
好消息;你所描述的（其现有的C＃类）有什么预期的使用情况protobuf网的。所有.proto的东西（硫辛酸，在VS加载项等）都被添加为后记。 protobuf网的核心不知道他们或关心他们。
协议缓冲区定义DSL（.proto，你提到），它的实现之间共享，并且是（有时）用于code一代。当我第一次写protobuf网，在code代方面是不是我最关心的 - 简单地说.NET开发者的普遍有罪（包括我自己）实施第一，而不是合同第一。
因此，protobuf网不需要.proto文件工作;一个属性类是足以明确序列化/反序列化。只需使用 Serializer.Serialize ， .Merge 和 .Deserialize （等）。
这表示;它的确实的包括一些非常欠发达和实验作为这种支持：
字符串原= Serializer.GetProto＆LT; YourType＆GT;（）;
这是远远没有完成，但可能工作的简单类型。如果你有它失败的一些具体情况，然后让我知道（添加评论或登录问题）。然而;大部分时间，感兴趣的.proto人会写.proto的第一的工作从那里。
工作装饰类型的例子显示在项目主页;这完全取决于你是否使用WCF属性，XML属性或protobuf网属性（尽管后者提供更多的控制某些特定的序列化点，比如继承和数字布局）。
Trying to get my mind around google protobuf. I found some implementation of protobuf in C# but they seems to lack one feature: the ability to generate .proto files automatically from an existing C# class decorated with attributes.
The reason I want to do it this way instead of going from auto-generated C# classes from .proto file is because I already have the C# classes defined in my project and I don't want to duplicate them just to satisfy ProtoBuf.
Does anyone have encountered such a scenario?
Update
Is this possible to just decorate a C# class and not use a .proto file to use protobuf?
Good news; what you have described (having existing C# classes) is the expected use-case of protobuf-net. All the .proto stuff ("protogen", the VS add-in, etc) were all added as afterthoughts. The core of protobuf-net doesn't know about them or care about them.
protocol buffers defines a DSL (.proto, as you mention) that is shared between implementations, and is (sometimes) used for code generation. When I first wrote protobuf-net, the code-generation aspect wasn't my biggest concern - simply that .NET developers are generally guilty (myself included) of "implementation first" rather than "contract first".
As a consequence, protobuf-net doesn't need .proto files to work; an attributed class is sufficient to unambiguously serialize/deserialize. Just use Serializer.Serialize , .Merge and .Deserialize (etc).
That said; it does include some very under-developed and experimental support for this:
string proto = Serializer.GetProto<YourType>();
This is far from complete, but may work for simple types. If you have some specific cases where it fails, then let me know (add a comment or log an issue). However; most of the time, people interested in .proto would write the .proto first and work from there.
Examples of working decorated types are shown on the project home page; it is entirely up to you whether you use WCF attributes, xml attributes or protobuf-net attributes (although the latter provide more control over some specific serialization points, such as inheritance and numeric layouts).
