基本的C＃，asp.net循環和CSS樣式
[英]basic c#, asp.net looping and css style
問題描述
我要達到什么目的：
試圖大致得到以下結果
[天數] [FixtureTeamHome] v [FixtureTeamAway]
[月份名稱] [簡短說明]，[地點]
在Page_load上，我檢索了包含所有固定裝置的“團隊詳細信息”頁面。首先，這是正確的方法，其次，我得到了所需的結果，但是如何將樣式添加為當前s + =“
感謝您的建議，幫助和指導
public partial class WebForm6 : System.Web.UI.Page { public string TeamTitle = null; public string TeamTitle1 = null; protected void Page_Load(object sender, EventArgs e) { DataView TeamRecordSet = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty); foreach (DataRowView DRV in TeamRecordSet) { lblTeamName.Text = DRV["TeamName"].ToString(); lblTeamNameShortInfo.Text = DRV["TeamShortInfo"].ToString(); Image1.ImageUrl = "~/style/images/teams/" + DRV["TeamPhoto"].ToString(); } DataView TeamFixtureRecordSet = (DataView)SqlDataSource2.Select(DataSourceSelectArguments.Empty); string s = "<ul class=\\"latest-posts\\" id=\\"TeamFIxtures\\">"; foreach (DataRowView DRV1 in TeamFixtureRecordSet) { int FixtureMonth = (int)DRV1["FixtureMonth"]; string strMonthName = CultureInfo.CurrentCulture.DateTimeFormat.GetAbbreviatedMonthName(FixtureMonth); s += "<li><span class=\\"date\\"><em class=\\"day\\">"; s += "</em><em class=\\"month\\">" + strMonthName + "</em></span>"; // Fixture ================================================================ // Home Team int FixtureTeamHomeID = (int)DRV1["FixtureTeamHomeID"]; TeamNameHome(FixtureTeamHomeID); s += "<a href=\\"#\\">" + TeamTitle + "</a>"; TeamTitle = null; s += " v "; // Away Team int FixtureTeamAwayID = (int)DRV1["FixtureTeamAwayID"]; TeamNameAway(FixtureTeamAwayID); s += "<a href=\\"#\\">" + TeamTitle1 + "</a><br />"; TeamTitle1 = null; // Venue s += "<a href=\\"#\\">" + DRV1["FixtureShortInfo"].ToString() + "</a><br /><br />"; s += "<a href=\\"#\\">" + DRV1["VenueID"].ToString() + "</a></li>"; } s += "</ul>"; lblTeamFIxtures.Text = s; } public void TeamNameHome(int arg1) { using (SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["WCDB_local"].ConnectionString)) { string sqlSelect = @"select TeamName from Teams where TeamID = @TeamID"; using (SqlCommand cmd = new SqlCommand(sqlSelect, conn)) { cmd.Parameters.AddWithValue("@TeamID", arg1); conn.Open(); TeamTitle = cmd.ExecuteScalar().ToString(); } } } public void TeamNameAway(int arg2) { Int32 myTeamID = arg2; using (SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["WCDB_local"].ConnectionString)) { string sqlSelect = @"select TeamName from Teams where TeamID = @TeamID"; using (SqlCommand cmd = new SqlCommand(sqlSelect, conn)) { cmd.Parameters.AddWithValue("@TeamID", arg2); conn.Open(); TeamTitle1 = cmd.ExecuteScalar().ToString(); } } } 我想我可能已經懷疑了它，並逐漸開始理解它背后的邏輯，請問這是否是解決此問題的正確方法？ 再次感謝大家，每一個小的建議都會有所幫助。

基本上，您將ASP經典技術與其他一些不太漂亮的代碼一起使用。
沒有火焰，但這使應用程序難以調試:)因此，這不是您問題的答案，而是查找提示
IMO的一個好起點是研究數據綁定/“實時綁定”，它基本上是在ASPNET中創建（設計）框架，然后將數據源綁定到它。 易於實施和維護
