Ruby WIN32OLE_VARIANT[i,j,...]用法及代碼示例

返回 WIN32OLE_VARIANT 對象(OLE 數組)的元素。此方法僅在 WIN32OLE_VARIANT 對象的變體類型為VT_ARRAY 時可用。

評論：

The all indices should be 0 or natural number and
lower than or equal to max indices.
(This point is different with Ruby Array indices.)

obj = WIN32OLE_VARIANT.new([[1,2,3],[4,5,6]])
p obj[0,0] # => 1
p obj[1,0] # => 4
p obj[2,0] # => WIN32OLERuntimeError
p obj[0, -1] # => WIN32OLERuntimeError
