Ruby WIN32OLE_VARIANT[i,j,...]用法及代码示例

返回 WIN32OLE_VARIANT 对象(OLE 数组)的元素。此方法仅在 WIN32OLE_VARIANT 对象的变体类型为VT_ARRAY 时可用。

评论：

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
