I have a piece of C# code that needs to convert a string array to a LPCWSTR to pass to a Win32 API function. I can’t find nothing in the Marshal class that makes it straightforward. Does anybody knows how to do that?

You should declare the API function as taking a string array. Since it’s declared as constant, you should add an
Inattribute so that it’s not marshalled back after the call. If the function truly only has a unicode version as you’ve specified (i.e., it takesLPCWSTRand notLPCTSTR), then you should declare it withCharSet=Unicode. Similar to:What API function are you trying to call? If you post it, I can give you a good P/Invoke signature for it. Or you can check pinvoke.net, which has a pretty good pre-compiled list (community-generated) of P/Invoke signatures.
