public string Pagelink(int pageSize, int recordCount, int currentPage, int prev, int next)
{
int pageCount = recordCount % pageSize == 0 ? (recordCount / pageSize) : ((int)Math.Ceiling((double)recordCount / pageSize));
StringBuilder sb = new StringBuilder();
if (currentPage > 1 && recordCount > 1)
{
sb.Append("sb.Append((currentPage - 1).ToString());
sb.Append("">前一页  ");
}
if (currentPage > prev + 1)
sb.Append("1 ... ");
if (currentPage < prev)
next = next + prev - currentPage + 1;
if (next > pageCount - currentPage)
prev = prev + next - (pageCount - currentPage);
for (int i = 1; i <= pageCount; i++)
{
if (i == currentPage)
{
sb.Append("" + i + "  ");
}
else
{
if (i > (currentPage - prev - 1) && i < (currentPage + next + 1))
{
sb.Append("" + i + "  ");
}
}
}
if (currentPage < pageCount - next)
sb.Append("... " + pageCount.ToString() + "");
if (currentPage < pageCount)
sb.Append("  后一页");
return sb.ToString();
