一、参考文章：
1. C# ListView Column Width Auto
http://stackoverflow.com/questions/1257500/c-sharp-listview-column-width-auto
2. C# Clear all items in ListView
http://stackoverflow.com/questions/435379/c-sharp-clear-all-items-in-listview
二、有效信息：
You gave the answer: -2 will autosize the column to the length of the text in the column header, -1 will autosize to the longest item in the column. All according to MSDN. Note though that in the case of -1, you will need to set the column width after adding the item(s). So if you add a new item, you will also need to assign the width property of the column (or columns) that you want to autosize according to data in ListView control.
