ListView排序功能的实现

ListView 控件是显示文件系统信息和显示来自 XML 或数据库的数据的非常好的方式。.NET所提供的ListView是不自带排序功能的，怎么办呢，自然是自己写代码来实现了，呵呵。
首先，得自己建立一个排序类：

ListView排序类#region ListView排序类
        /**//// <summary>
        /// ListView排序类
        /// </summary>
        public class ListViewItemComparer : IComparer 
        {
            private int col;
            private SortOrder order;

            public ListViewItemComparer() 
            {
                col=0;
                order = SortOrder.Ascending;
            }
            public ListViewItemComparer(int column , SortOrder order) 
            {
                col=column;
                this.order = order;
            }
            public int Compare(object x, object y) 
            {
                int returnVal = -1;
                returnVal = String.Compare(((ListViewItem)x).SubItems[col].Text,((ListViewItem)y).SubItems[col].Text);

                 if(order == SortOrder.Descending)
                    returnVal *= -1 ;
                return returnVal;
            }
        }
        #endregion

排序代码：

/**//// <summary>
        /// 排序方式(ListView)
        /// </summary>
        private int sortColumn = -1;
/**//// <summary>
        /// ListView间隔行背景色设置
        /// </summary>
        /// <param name="lv">ListView控件ID</param>
public static void SetListViewColor(ListView lv)
        {
            bool b = false;
            foreach(ListViewItem li in lv.Items)
            {
                if(b)
                    li.BackColor = System.Drawing.Color.FromArgb(230,240,255);
                else
                    li.BackColor = System.Drawing.Color.FromArgb(255,255,255);
                b = !b;
            }
        }
ListView排序事件#region ListView排序事件
        private void LVCompany_ColumnClick(object sender, System.Windows.Forms.ColumnClickEventArgs e)
        {
            if( e.Column < 3 )
            {                
                if (e.Column != sortColumn)
                {
                    sortColumn = e.Column;
                    LVCompany.Sorting = SortOrder.Ascending;
                }
                else
                {
                    if (LVCompany.Sorting == SortOrder.Ascending)
                        LVCompany.Sorting = SortOrder.Descending;
                    else
                        LVCompany.Sorting = SortOrder.Ascending;
                }
                
                this.LVCompany.ListViewItemSorter = new epbs.Company.ListViewItemComparer(e.Column,
                    LVCompany.Sorting);
                LVCompany.Sort();
                epbs.epbsTool.SetListViewColor( LVCompany ) ;
            }
        }
        #endregion
