在顯示全部數據的基礎上，增加了“查詢”功能，但是不分頁。
一、前臺代碼

二、後臺代碼
<code>using
System;using
System.Collections.Generic;using
System.Linq;using
System.Web;using
System.Web.UI;using
System.Web.UI.WebControls;namespace
guolei.Web {public
partialclass
query
: System.Web.UI.Page {protected
void
Page_Load
(object sender, EventArgs e)
{string
keywords = Request.QueryString["keywords"
];if
(!Page.IsPostBack) { txtKeywords.Text =keywords; RepList1.DataSource =new
DAL.title().GetList(keywords); RepList1.DataBind(); Response.Write(new
DAL.title().GetCount(keywords) ); } }protected
void
btnSearch_Click
(object sender, EventArgs e)
{ Response.Redirect("query.aspx?keywords="
+ txtKeywords.Text); }protected
void
btn_all_Click
(object sender, EventArgs e)
{ Response.Redirect("query.aspx"
); } } }/<code>
三、DAL數據訪問代碼
<code>public
DataTableGetList
(
string
strWhere) { StringBuilder strSql =new
StringBuilder(); strSql.Append("select * from title where"
); strSql.Append(CombSqlTxt(strWhere));return
new
SqlHelper().ExecuteQuery(strSql.ToString(), CommandType.Text); }public
int
GetCount
(
string
strWhere) { StringBuilder strSql =new
StringBuilder(); strSql.Append("select count(*) from title where"
); strSql.Append(CombSqlTxt(strWhere));return
Convert.ToInt32(new
SqlHelper().ExecuteScalar(strSql.ToString(), CommandType.Text)); }/<code>
<code>protected
string
CombSqlTxt
(
string
_keywords) { StringBuilder strTemp =new
StringBuilder();if
(!string
.IsNullOrEmpty(_keywords)) { strTemp.Append(" title like '%"
+ _keywords +"%'"
); }else
{ strTemp.Append(" 1=1"
); }return
strTemp.ToString(); }/<code>
