復制代碼 代碼如下:

/// <summary>
/// 獲取新聞數據列表
/// </summary>
/// <param>請求數量</param>
/// <param>類別ID</param>
/// <param>是否置頂</param>
/// <param>是否推薦</param>
/// <returns>一個新聞數據集,News是新聞,當然,List<XXXX>名稱取決于你的數據源</returns>
protected List<News> GetNewsData(int num,int cateId,int isTop,int isCommend){
if (num < 0) num = 0;
List<News> result = new List<News>();
Expression<Func<News, bool>> expr = PredicateExtensionses.True<News>();
if (isPic) {
expr = expr.And(c => c.IsPic == 1);
}
if (cateId > 0) {
expr = expr.And(c => c.cateId == cateId);
}
if (isTop > -1) {
expr = expr.And(c => c.IsTop == isTop);
}
if (isCommend > -1) {
expr = expr.And(c => c.IsCommend == isCommend);
}
return nm.AllNews.Where(expr).OrderByDescending(c=>c.ID).Take(num).ToList();
}

復制代碼 代碼如下:

protected void Page_Load(object sender, EventArgs e)
{
DataBind();
}

復制代碼 代碼如下:

<asp:Repeater runat="server" DataSource='<%#GetNewsData(10,3548,-1,-1)%>'>
<ItemTemplate>
<%#Eval("Subject")%>
</ItemTemplate>
</asp:Repeater>
