问题
When compiling my solution, I get several warnings of the following:
warning CS3016: Arrays as attribute arguments is not CLS-compliant
No other information on what type is not compliant is given. In my projects I have some attributes that take params array arguments in their constructors, but they are all internal, and that shouldn't affect CLS-compliance. Why is this warning being given, and what type is it being given on?
回答1:
CS3016.
If you have an attribute which takes an array as argument and the project is marked as CLSCompliant you will get this warning.

I ran into this today. I had 4 instances of the warning showing up. I then found that I had the attribute decorating 4 public methods in that assembly. As I removed them one by one, the errors went away one by one.
Also, if you are OK with not being CLS compliant, you can put [CLSCompliant(false)] on the methods decorated with the attribute (or the class on which the methods are defined). Putting it on the offending attribute constructor/class doesn't do the trick. I guess this makes sense since ultimately the attribute is probably exposed outside the assembly as part of the public method's metadata.

I ran into the same issue, and what I had to do was to use the "Find in Files" dialog in VS2010 select Use: Wildcards and in the Find What: text box, enter
\[*\(*\)\]
That produces a list of all attribute instances. Went one by one and I was able to identify and correct the warnings.
