We're talking in the context of WPFGrid here? My answer will talk about columns, but the same applies to rows.
我们是在WPFGrid的上下文中讨论的？我的回答将讨论列，但同样适用于行。
In brief:
- Automeans size to column contentand
- *means size proportional to grid
简而言之：
-Auto表示与列内容的大小和
- *表示与网格成比例的大小
Automeans that a column is given as much width as the elements within it require.
The width of *sized columns is calculated by allocating space for the Auto, and fixed width columns, and then dividing up the remaining space. So if there's only one *sized column, it will get all the remaining space, if there were two they would get half each, etc. You can also change the proportion allocated to each star sized column.
Auto意味着列的宽度与其中的元素所需的宽度相同。*大小列的宽度是通过为Auto、 和固定宽度列分配空间，然后划分剩余空间来计算的。因此，如果只有一个*大小的列，它将获得所有剩余空间，如果有两个，它们将各获得一半，等等。您还可以更改分配给每个星号大小的列的比例。
If column A had a size of 2*and B had a size of 3*then whole column space is divided into 5 equal shares; column A would get 2 shares of the space and B would get 3 shares.
如果 A 列的大小为2*，B3*列的大小为 ，则整个列空间被分成 5 等份；A 列将获得 2 份空间，B 列将获得 3 份。
