            foreach (FileInfo f in infos)

You can Split string by . and Take the first two elements from the split array and Join as a string. You will get the desire file name with an extension.

//I showed you minimal example to solve your problem, update your code accordingly.
var infos = new List<string>(){"Compatible.xml.8790.done", "Compatible.xml.8790.done"};
foreach (var f in infos)
{
   var newFileName = string.Join(".",  f.Split('.').Take(2)); 
   Console.WriteLine(newFileName);     
}
