ASP.NET 分頁技術

 以下是我自己編寫的asp.net分頁的一個方法，希望能給大家多多指點。
public static StringBuilder PageBtn(int currentPage, int numInOneLine, string url, PagedDataSource pds)//返回索引字串,numInOneLine為每行索引的個數,currentPage為當前頁;
    {
            StringBuilder sb = new StringBuilder();
            int currentLine; //當前索引行

            if (currentPage % numInOneLine != 0)//判斷當前頁是否為每行索引的個數的整數倍;
            {
                currentLine= currentPage / numInOneLine + 1;
            }
            else
            {
                currentLine=currentPage / numInOneLine;
            }
            //添加上一索引行串連
            if (currentLine == 1)
            {
                sb.Append("<<&nbsp");
            }
            else
            {
                sb.Append("<a href='");
                sb.Append(url);
                sb.Append("?currentPage=");
                sb.Append(Convert.ToString((currentLine-1)*numInOneLine));
                sb.Append("'><<</a>&nbsp");
            }

            //添加頁碼索引
            for (int i = 1; i <= numInOneLine; i++)
            {
                //<a href="Datalist.aspx" style="color:Red">[]</a>
                if ((currentLine - 1) * numInOneLine + i<=pds.PageCount)//判斷頁碼是否出界;
                {
                    if ((currentLine - 1) * numInOneLine + i == currentPage)//判斷索引頁碼是否為當前頁
                    {
                        sb.Append("&nbsp<font style='color:Red; text-decoration: none;'>");
                        sb.Append(currentPage.ToString());
                        sb.Append("</font>&nbsp");
                    }
                    else
                    {

                        sb.Append("<a href='");
                        sb.Append(url);
                        sb.Append("?currentPage=");
                        sb.Append(Convert.ToString((currentLine - 1) * numInOneLine + i));
                        sb.Append("'>[");
                        sb.Append(Convert.ToString((currentLine - 1) * numInOneLine + i));
                        sb.Append("]</a>&nbsp");
                    }
                }
            }

            int totalLine;//定義總索引行數
            if (pds.PageCount % numInOneLine != 0)//判斷總頁數是否為每行索引的個數的整數倍;
            {
                totalLine = pds.PageCount / numInOneLine + 1;
            }
            else
            {
                totalLine = pds.PageCount / numInOneLine;
            }
            //添加下一索引行
            if (currentLine == totalLine)
            {
                sb.Append(">>");
            }
            else
            {
                sb.Append("<a href='");
                sb.Append(url);
                sb.Append("?currentPage=");
                sb.Append(Convert.ToString(currentLine * numInOneLine + 1));
                sb.Append("'>>></a>");
            }
       
        return sb;

    }
