These days  once you have LINQ available  you can convert the dictionary keys and their values to a single string    You can use the following code      convert the dictionary to an array of strings string   strArray   dict Select x   gt    Key      x Key      Value      x Value   ToArray        convert a string array to a single string string result   String Join       strArray

Store it in a list  It is easier   List lt Foo gt  arr   new List lt Foo gt  dict Values     Of course if you specifically want it in an array   Foo   arr    new List lt Foo gt  dict Values   ToArray

There is a ToArray   function on Values   Foo   arr   new Foo dict Count       dict Values CopyTo arr  0     But I don t think its efficient  I haven t really tried  but I guess it copies all these values to the array   Do you really need an Array  If not  I would try to pass IEnumerable   IEnumerable lt Foo gt  foos   dict Values

If you would like to use linq  so you can try following   Dictionary lt string  object gt  dict   new Dictionary lt string  object gt     var arr   dict Select z   gt  z Value  ToArray      I don t know which one is faster or better  Both work for me
