asp.net Linq TO Sql 分页方法

2019-07-07 16:34ASP.NET之家 ASP.NET教程

临近春节,手头工作已告一段落,闲来无事写了一个 linq to sql 分页方法。代码若有不妥之处,请各位高手多提宝贵意见。

分页方法 
复制代码代码如下:

/// <summary> 
/// 
/// </summary> 
/// <typeparam name="T"></typeparam> 
/// <param name="replist">控件ID</param> 
/// <param name="DataSource">数据源</param> 
/// <param name="IndexPage">当前页</param> 
/// <param name="PageSize">每页数据条数</param> 
/// <param name="PageParemart">页面搜索参数 like &a=a&b=b </param> 
/// <returns></returns> 
public static string ShowPage<T>(System.Web.UI.WebControls.Repeater replist, IQueryable<T> DataSource, int IndexPage, int PageSize, string PageParemart) 

string rtnStr = ""; 
int sourceCount = DataSource.Count(); 
if (sourceCount == 0)//数据源无数据 

rtnStr = string.Empty; 

else 

int yutemp = sourceCount % PageSize; 
int pagecounts = (yutemp == 0) ? (sourceCount / PageSize) : (sourceCount / PageSize + 1);//总页数 
rtnStr = " <div style='width:100%;'><div style=' float:left;'>页次:" + IndexPage + "页/" + pagecounts + "页,共" + sourceCount + "条记录</div> "; 
if (pagecounts == 1) //总共一页数据 

replist.DataSource = DataSource; 
rtnStr += "[首页] [上一页] [下一页] [尾页] "; 

else 

rtnStr += "<div style=' float:right;'>"; 
if (IndexPage == 1)//首页 

replist.DataSource = DataSource.Take(PageSize); 
rtnStr += "[首页] [上一页] <a href='?page=" + (IndexPage + 1) + PageParemart + "'>[下一页]</a> <a href='?page=" + (pagecounts) + PageParemart + "'>[尾页]</a> "; 

else 

replist.DataSource = DataSource.Skip((IndexPage - 1) * PageSize).Take(PageSize); 
if (IndexPage == pagecounts)//末页 

rtnStr += "<a href='?page=1" + PageParemart + "'>[首页]</a> <a href='?page=" + (IndexPage - 1) + PageParemart + "'>[上一页]</a> [下一页] [尾页] "; 

else 

rtnStr += "<a href='?page=1" + PageParemart + "'>[首页]</a> <a href='?page=" + (IndexPage - 1) + PageParemart + "'>[上一页]</a> <a href='?page=" + (IndexPage + 1) + PageParemart + "'>[下一页]</a> <a href='?page=" + (pagecounts) + PageParemart + "'>[尾页]</a> "; 


rtnStr += "</div></div>"; 

replist.DataBind(); 

return rtnStr; 

页面调用 
复制代码代码如下:

private int PageSize = 10; 
private int IndexPage = 1; 
private string PageParemart = ""; 
private void Bind() 

strwhere = "1=1 " + strwhere; 
str2 = "1=1 " + str2; 
var a = from b in datas.fav_Awards_User select b; 
Label2.Text = common.PageFen.ShowPage(replist, a, this.IndexPage, this.PageSize, this.PageParemart); 
if (Label2.Text == "") 

Label1.Visible = true;
