ASP.NET+SQLServer2008分页，方面简单实用

/// <summary>
/// 分页获取数据列表
/// </summary>
/// <param name="strWhere">条件，以and开头</param>
/// <param name="orderby">排序方式</param>
/// <param name="pageindex">当前页-1</param>
/// <param name="pagesize">分页尺寸</param>
/// <returns></returns>
public DataSet GetListByPage(string strWhere, string orderby, int pageindex, int pagesize)
{
    string tablename = "t_JinYinShangHu";
    StringBuilder strSql = new StringBuilder();

    strSql.Append("select top " + pagesize + " * from " + tablename + " where id not in ");
    strSql.Append(" (");
    strSql.Append("     select top " + pageindex * pagesize + " id from " + tablename + " order by " + orderby);
    strSql.Append(" )");
    strSql.Append(strWhere);
    strSql.Append(" order by " + orderby);
    return DbHelperSQL.Query(strSql.ToString());
}

后续追加几种方法性能的比较，暂时先这么用。
