一、参考文章：
    C# ListView Column Width Auto
        http://stackoverflow.com/questions/1257500/c-sharp-listview-column-width-auto

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.
