Fine, but when I try and use {"A"} in a function parameter that expects string[] column, I get the following error:

"Invalid expression term '{"

Why?

string[] columns = {"A"} is a shortcut to string[] columns = new string[]{"A"}.  This type of shortcut can only be used during variable declaration.  So, when you call a function with an array parameter you should use the following syntax:

myfunction( new string[] {"A"} );
