Keep '_' in property name in C# generated code

[VaronisDNMacClient]

Hi,

From trial and error, the style guide and source code I see that all recurrences of the character '_' are eliminated from property name when generating C# code.

Can this be overridden or avoided in some way? I need my properties with underscore (or any other char that can be perceived as a separator).

In addition to that, is there a way to specify "Keep property names as is" for the generated C# code? If not, is there an easy way to get property name for corresponding field name inside .proto file?
I am generating .proto file on the fly, pass it through protoc to generate C# code and I generate some more C# code that populates the protobuf objects to drive further business logic. My problem is that I don't have a mapping of field names that I generated within .proto file and the corresponding property names that protoc generated.

Have you tried Descriptors? Sample usage:

Thanks @anandolee . I already tried that but it doesn't quite give what I want. Imagine protobuf message like this -

    message FooMulInputType {
        repeated sint32 param1 = 1;
        repeated sint32 Param2 = 2;
        repeated sint32 p_aram3 = 3;
        repeated sint32 p_aram_4 = 4;
    }

If i do something like this, I don't get desired ouput:

FieldDescriptor par1 = FooApisType.Types.FooMulInputType.Descriptor.FindDescriptor<FieldDescriptor>("p_aram3");
Console.WriteLine(par1.Name); // "p_aram3"

But this is not the property name that is generated in C#. See below screenshot that shows property names protoc.exe has generated and I want a way to get these property names instead. Let me know if there is a way to do that.

It is in the FieldDescriptor.propertyName: https://github.com/google/protobuf/blob/047575f20cbdee8fb2f88d78a317ffe6133b93e6/csharp/src/Google.Protobuf/Reflection/FieldDescriptor.cs#L46

I think it is reasonable to make a public get API for the propertyName. Are you happy to make a PR for it?

[kunalspathak]

sure, will do it sometime.

[anandolee]

Friendly ping. @kunalspathak do you get time for it?

[kunalspathak]

sorry, not yet. I might have some time starting 1st week of August.

Has anyone found or implemented a way to keep the _ in field names instead of forcing camelCase?

Closing this due to the fix in #7642.
