C＃listview最佳列宽(C# listview optimum column width)

我有一个C＃ListView，我想根据列的内容自动调整列宽。

我知道将列宽设置为-1会使列在最宽成员的长度上调整大小。 我知道将列宽设置为-2会使列的大小与列标题的长度相符。 如何将列的大小设置为两者中的较大者？

我可以这样做：

for (int i = 0; i < listView.Columns.Count; ++i) { listView.Columns[i].Width = -1; int width1 = listView.Columns[i].Width; listView.Columns[i].Width = -2; if (width1 > listView.Columns[i].Width) listView.Columns[i].Width = -1; }

但它确实看起来非常低效。

有没有人有答案？

I have a C# ListView and I'd like to autosize the column widths based on the contents of the column.

I know that setting the column width to -1 will size the column at the length of the widest member. I know that setting the column width to -2 will size the column at the length of the column header. How do I size the column to be the greater of the two?

I could do something like this:

for (int i = 0; i < listView.Columns.Count; ++i) { listView.Columns[i].Width = -1; int width1 = listView.Columns[i].Width; listView.Columns[i].Width = -2; if (width1 > listView.Columns[i].Width) listView.Columns[i].Width = -1; }

but it does seem fabulously inefficient.

Does anyone have an answer?

你应该试试

ListView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);

即使它显示“ColumnHeaderAutoResizeStyle.HeaderSize”，它也应该自动调整大小到列中最大的项目，无论是标题还是列成员

You should try

ListView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);

even though it says "ColumnHeaderAutoResizeStyle.HeaderSize" it should auto resize to the largest item in the column, whether it's the header or a column member
