I have a project with 5000+ resource strings in it. Almost all of them have periods in their identifier.
We're switching over to automatically generating strongly-typed classes, and of course, because of the periods, we see a few thousand warnings
The resource name 'blah' is not a valid identifier.
I know it isn't, the generator changes periods to underscores, and everything is fine.
Can I suppress the warning? It doesn't seem to have an associated number to #pragma away.
I think I can repro, although it isn't crystal in the question. Project + Properties, Resources and type a string resource name like "foo.bar" triggers this warning.
Yes, you cannot suppress this warning, it is generated by the resource designer in the IDE. When it auto-generates the code from the Properties\Resources.resx file to the Properties\Resources.Designer.cs file. Look at the .resx file and check the "name" attribute on the <data> elements. A period in the attribute value is going to trigger the warning.
A carefully crafted search-and-replace with regexp could fix that by turning the periods into underscores. That gives me personally two problems, I'd just write a little program that uses XDocument. Also check if you still need this auto-generated code, sounds like you are replacing it.
