之前自己一直用Aspnetpager控件来显示项目中的分页,但是每次都要拖一个aspnetpager的控件进去,感觉很不舒服,因为现在自己写的webform都不用服务器控件了,所以自己仿照aspnetpager写了一个精简实用的返回分页显示的html方法,其他话不说了,直接上代码。
 
分页显示信息的实体类:
 
public class Pager
    {
        private string _firstPageText;
        /// <summary>
        /// 最前一页文字显示 默认显示为"首页"
        /// </summary>
        public string FirstPageText
        {
            get {
                return string.IsNullOrEmpty(_firstPageText)? "首页" : _firstPageText;
            }
            set {
                _firstPageText = value;
            }
        }

private string _prePageText;
        /// <summary>
        /// 上一页文字显示 默认显示为"上一页"
        /// </summary>
        public string PrePageText
        {
            get
            {
                return string.IsNullOrEmpty(_prePageText) ? "上一页" : _prePageText;
            }
            set
            {
                _prePageText = value;
            }
        }

private string _nextPageText;
        /// <summary>
        /// 下一页文字显示 默认显示为"下一页"
        /// </summary>
        public string NextPageText

            get
            {
                return string.IsNullOrEmpty(_nextPageText) ? "下一页" : _nextPageText;

分页显示html代码的拼接方法:
 
public class SplitManager
    {
                public static string AspNetPagers(Pager pager)
        {
            StringBuilder sb = new StringBuilder();
            string attr="";

            int floorcount = 0;//分页的总层数
            int currentLastPage = 0;//当前最后一页的页码
            int pageNum = pager.RecordCount / pager.PageSize + 1;//总页数 1~24
            sb.AppendFormat("<div class=\"{0}\">\n", pager.ClassName);
            attr=pager.PageIndex==1?"disabled=disabled":"";//标志当前页第一页是否相等 来控制前俩个按钮的有效性
            sb.AppendFormat(GetAHtml(attr,string.Format(pager.URL,1),pager.FirstPageText));//添加最前一页的代码

            sb.AppendFormat(GetAHtml(attr, string.Format(pager.URL, pageNum), pager.LastPageText));//添加最后一页的代码

            {

                sb.AppendFormat("<a href=\"#\" style=\"float:none;\" onclick=\"javascript:jump();\">" + pager.SubmitButtonText + "</a></span>\n");
                sb.Append(GetJumpScript(pager.URL));//添加按钮跳转的javascript代码

                        "}\n"+
                "</script>\n";
            return scriptstr;
        }

}

最精简必要的几个参数传进去就能显示分页效果了:
 
protected string str = "";
        protected void Page_Load(object sender, EventArgs e)
        {
            Pager pager = new Pager() { RecordCount = 350,
                PageSize = 15,
                MaxShowPageSize=10,
                PageIndex = Convert.ToInt32(Request.QueryString["page"]),
            ShowSpanText=true};
            str = SplitManager.AspNetPagers(pager);

}

仿csdn的分页的效果图

供测试的css:
 
<style type="text/css">
        /*分页样式控制的开始*/
.paginator { font: 12px Arial, Helvetica, sans-serif;
             padding:10px 20px 10px 0;
             margin: 0px;}
.paginator a {border:solid 1px #ccc;
              color:#0063dc;
              cursor:pointer;
              text-decoration:none;}
.paginator a:visited {padding: 1px 6px;
                      border: solid 1px #ddd;
                      background: #f0f1f1;
                      text-decoration: none;}
.paginator .cpb {border:1px solid #14316b;
                 font-weight:700;
                 color:#f0f1f1;
                 }
.paginator a:hover {border:solid 1px #14316b;
                    color:#14316b;
                    text-decoration:none;}
.paginator a,.paginator a:visited,.paginator .cpb,.paginator a:hover{float:left;
                                                                     height:16px;
                                                                     line-height:16px;
                                                                     min-width:10px;_width:10px;
                                                                     margin-right:5px;
                                                                     text-align:center;
                                                                     white-space:nowrap;
                                                                     font-size:12px;
                                                                     font-family:
                                                                     Arial,SimSun;
                                                                     padding:0 3px;}
.paginator .stc{color:#999;margin-left:20px;}
.paginator .stc a{margin-left:10px;}
/*分页样式控制的结束*/
    </style>

同时配合为了配合分页,再给出一个DataTable转泛型列表的一个方法和一个分页存储过程。
此转换方法需配合相应的实体类,并且实体类中需对象相应表的字段名,不区分大小写。
 
 #region DataTable To List/Model

/// <summary>

        /// </summary>
        /// <typeparam name="TType">object type</typeparam>
        /// <param name="dt">DataTable</param>

        public static List<T> DataTableToObjectList<T>(DataTable dt) where T : new()
        {
            DataRowCollection drc = dt.Rows;
            int columncount = drc.Count;
            List<T> result = new List<T>();    //declare the generic type of return
            Type type = typeof(T);
           
            PropertyInfo[] propertys = type.GetProperties(BindingFlags.IgnoreCase|BindingFlags.Instance|BindingFlags.Public|BindingFlags.SetProperty);   //get the collections of the model
            foreach (DataRow r in drc)
            {
                result.Add(DataRowToObjectModel<T>(r, propertys));
            }    
            return result;
           
        }
       
        /// <summary>
        /// DataRow To a Model
        /// </summary>
        /// <typeparam name="T">the type of Model</typeparam>
        /// <param name="r">DataRow</param>
        /// <param name="propertys">the object to Model</param>
        /// <returns>return a Model Type</returns>
        private static T DataRowToObjectModel<T>(DataRow r, PropertyInfo[] propertys) where T : new()
        {
            T t = new T();
            for (int i = 0; i < propertys.Length; i++)
            {
                object obj = r[propertys[i].Name];
                if (obj != null)
                {
                    if (propertys[i].PropertyType == typeof(int))
                        propertys[i].SetValue(t, PublicMethod.GetInt(obj), null);
                    if (propertys[i].PropertyType == typeof(string))
                        propertys[i].SetValue(t, obj.ToString(), null);
                    if (propertys[i].PropertyType == typeof(DateTime))
                        propertys[i].SetValue(t, PublicMethod.GetDateTime(obj), null);
                }
            }
            return t;
        }
        #endregion

分页存储过程。
 
CREATE PROCEDURE [dbo].[proc_SplitPage]
    -- Add the parameters for the stored procedure here
