GetNumberOfTuples returns the number of entries in the array (the length).

GetNumberOfComponents returns the number of elements in each entry.
  For example and array holding temperature would be 1, an array for wind
direction could be 2, an array for RGB colors would be 3 etc.

Multiply the two by GetDataTypeSize will give you the total number of bytes.
