分页

代码如下：

    public static string GetPageControl(int CurrentPage, int TotalPage, string Url)
        {
            int intStartPage = 0;
            int intEndPage = 0;
            StringBuilder strbControlHTML = new StringBuilder();
     
            //如果当前页不是第一页，显示上一页
            if (CurrentPage != 1)
            {
                strbControlHTML.Append("<a href=\"" + string.Format(Url, CurrentPage - 1) + "\">上一页&nbsp;</a>");
            }
            
            //如果当前页小于5或总页码小于等于6
            if (CurrentPage < 5 || TotalPage <= 6)
            {
                intEndPage = (TotalPage < 6) ? TotalPage - 1 : 5;
                if (intEndPage <= 1) intEndPage = -1;
                for (int i = 0; i <= intEndPage; i++)
                {
                    if (CurrentPage == i + 1)
                    {
                        strbControlHTML.Append("<a href=\"" + string.Format(Url, i + 1) + "\" style=\"font-weight:bold;\">" + (i + 1) + "</a>");
                    }
                    else
                    {
                        strbControlHTML.Append("<a href=\"" + string.Format(Url, i + 1) + "\">" + (i + 1) + "</a>");
                    }
                }
                if (TotalPage > 6 ) strbControlHTML.Append("…<a href=\"" + string.Format(Url, TotalPage) + "\">" + TotalPage + "</a>");
            }
            else if (CurrentPage < TotalPage - 4)
            {
                strbControlHTML.Append("<a href=\"" + string.Format(Url, 1) + "\">" + 1 + "</a>…");
                intStartPage = CurrentPage - 4;
                if (intStartPage <= 0) intStartPage = 1;
                for (int i = intStartPage; i <= CurrentPage + 2; i++)
                {
                    if (CurrentPage == i + 1)
                    {
                        strbControlHTML.Append("<a href=\"" + string.Format(Url, i + 1) + "\" style=\"font-weight:bold;\">" + (i + 1) + "</a>");
                    }
                    else
                    {
                        strbControlHTML.Append("<a href=\"" + string.Format(Url, i + 1) + "\">" + (i + 1) + "</a>");
                    }
                }
                strbControlHTML.Append("…<a href=\"" + string.Format(Url, TotalPage) + "\">" + TotalPage + "</a>");
            }
            else
            {
                strbControlHTML.Append("<a href=\"" + string.Format(Url, 1) + "\">" + 1 + "</a>…");
                intStartPage = CurrentPage - 4;
                if (intStartPage <= 0) intStartPage = 1;
                for (int i = intStartPage; i < TotalPage; i++)
                {
                    if (CurrentPage == i + 1)
                    {
                        strbControlHTML.Append("<a href=\"" + string.Format(Url, i + 1) + "\" style=\"font-weight:bold;\">" + (i + 1) + "</a>");
                    }
                    else
                    {
                        strbControlHTML.Append("<a href=\"" + string.Format(Url, i + 1) + "\">" + (i + 1) + "</a>");
                    }
                }
            }
            
            //如果不是最后一页且总页数大于0显示 下一页
            if (CurrentPage != TotalPage && TotalPage > 0) strbControlHTML.Append("<a href=\"" + string.Format(Url, CurrentPage + 1) + "\">&nbsp;下一页</a>");
            
            
            return strbControlHTML.ToString();
        }
