import doesn't work about protobuf-csharp-port HOT 7 CLOSED

[deleted comment]

I also encountered this problem. --proto_path doesn't work. You need to compile 
all files together - "ProtoGen.exe second.proto first.proto". It's poor 
variant, but it work.

This could just be part of how the new code invokes protogen. I intend to look 
at it when I get some time...

You should be able to run:

ProtoGen.exe --include_imports second.proto

If they are in different directories, say "/sample/dir1/first.proto" and  
"/sample/dir2/second.proto" then you need to get a little more fancy...  First 
make sure second.proto includes the relative path from 'root': 
"dir1/first.proto".  Then run "ProtoGen.exe second.proto --include_imports 
--proto_path=/sample".

--include_imports helped.
Thanx.
Close issue please.

Closing as requested.

--include_imports is the root of the issue described here.

Additionally there was some confusion about the use of --proto_path from the 
command-line.  Specifically the following command-line failed:

"ProtoGen.exe dir2/second.proto --include_imports --proto_path=/sample"

The reason is that the specification of "dir2/second.proto" must be fully 
qualified (or have the same qualifier as --proto_path).

A change was made to determine that the argument "dir2/second.proto" exists 
under the specified proto_path "/sample", and to automatically combine the 
directories prior to handing them to protoc.  This should alleviate some 
confusion about the usage; however, one should generally use fully-qualified 
paths whenever possible on the command-line.
