推荐答案

我们是在 WPF Grid 的上下文中讨论的?我的回答将讨论列，但同样适用于行.

We're talking in the context of WPF Grid here? My answer will talk about columns, but the same applies to rows.

简而言之:
- Auto 表示根据列内容调整大小和
- * 表示大小与网格成正比

In brief:
- Auto means size to column content and
- * means size proportional to grid

Auto 意味着列的宽度与其中的元素所需的宽度相同.* 大小的列的宽度是通过为 Auto 和固定宽度的列分配空间，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.

Auto means 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.

如果A列的大小为2*，B列的大小为3*，那么整个列空间被分成5等份；A 列将获得 2 份空间，B 列将获得 3 份.

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.
