Initializing ArrayList with constant literal

Can the ArrayList below be initialized directly without the need for aFileExt string array?

private static string[] aFileExt = 
     {"css", "gif", "htm", "html", "txt", "xml" };
private System.Collections.ArrayList alFileTypes =
     new System.Collections.ArrayList(aFileExt);

The line below is the goal, but my .Net Compiler does not like it:

private static System.Collections.ArrayList alFileTypes = 
     new System.Collections.ArrayList({"css","gif","htm","html","txt","xml"});

I am using the .net Micro Framework and thus do not have access to generic types.
