字体滚动

      for (int i = 0; i < N; i++)
            {
                string str;
                str = textBox1.Text.Substring (N-1) + textBox1.Text.Substring(0, N - 1);
                textBox1.Text = str;
              System.Threading.Thread.Sleep(1000);
            }用for循环实现字体滚动为什么不行

  1.   

    for (int i = 0; i < N; i++)
                {
                    string str;
                    str = textBox1.Text.Substring (N-1) + textBox1.Text.Substring(0, N - 1);
                    textBox1.Text = str;
                   Application.DoEvents();
                  System.Threading.Thread.Sleep(1000);
                }
      

  2.   

    for (int i = 0; i < N; i++)
                {
                    string str;
                    str = textBox1.Text.Substring (i-1) + textBox1.Text.Substring(0, i - 1);
                    textBox1.Text = str;
                   Application.DoEvents();
                  System.Threading.Thread.Sleep(1000);
                }

    给你一个js写的吧，从后台数据库取需要滚动的字，上一个项目用到的，刚好写了，代码看起来比较多，但是实用！~~~~
    前台：<body style="margin: 0px" <%=stringGongGao%>>
        <form id="form1" runat="server">   
    <table width="100%" height="25" border="0" cellpadding="0" cellspacing="0">
            <tr>
              <td class="td">
                <div class="d1" id="div1" onmouseover="clearInterval(timer)" onmouseout="timer=setInterval(mar,30)">
                    <div  id="scroll">
                       <div class="div2" id="div2">
                           <a href="#" target="_self" id="detail_link"><span id="detail"></span></a>
                       </div>
                       <div id="div3" class="div2"></div>
                    </div>
                </div>
              </td>
    </table>
     </form>
    </body>后台：
    protected string stringGongGao;
     protected void Page_Load(object sender, EventArgs e)
            {
                if (!IsPostBack)
                {
                    //Button2.Attributes.Add("target", "mainframe");
                    Models.login_user userName = new bllUser().GetUserInfo(Session["uid"].ToString());
                    Label1.Text = userName.user_name;
                    lb_riqi.Text = DateTime.Now.ToString("yyyy年MM月dd日") + xq();
                    //lb_xingqi.Text =DateTime.Now.ToString("T");                stringGongGao = GetStr();
                    
                    
                }
                
            } private string GetStr()
            {
               
                string strS = string.Empty;
                string strSql = @"select ......";
                DataSet ds = GetTable(strSql);
                string str = ds.Tables[0].Rows[0][0].ToString();
                strS = "onload=init('" + str + "')";
               
                return strS;
            }js：
    var s, s2, s3, s4, timer;
    function init(details) {
        fillFont(details);
        s = getid("div1");
        s2 = getid("div2");
        s3 = getid("div3");
        s4 = getid("scroll");
        s4.style.width = (s2.offsetWidth * 6 + 100) + "px";
        s3.innerHTML = s2.innerHTML;
        timer = setInterval(mar, 30)
    }
    function mar() {
        if (s2.offsetWidth <= s.scrollLeft) {
            s.scrollLeft -= s2.offsetWidth;
        } else { s.scrollLeft++; }
    }
    function getid(id) {
        return document.getElementById(id);
    }
    function fillFont(details) {
        detail.innerHTML = details;
    }

    补充一下，css你自己设计样式吧~~~后台语句//Button2.Attributes.Add("target", "mainframe");
                    Models.login_user userName = new bllUser().GetUserInfo(Session["uid"].ToString());
                    Label1.Text = userName.user_name;
                    lb_riqi.Text = DateTime.Now.ToString("yyyy年MM月dd日") + xq();
    没有用！
