推荐答案

< a href =http://en.wikipedia.org/wiki/Syntax_error> Syntax_error [ ^ ]



使用此更正后的代码..

Syntax_error[^]

Use this corrected code..

protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                SortedList s1 = new SortedList();
                s1.Add("01", "C");
                s1.Add("04", "sql server");
                s1.Add("03", ".net");
                s1.Add("02", "c++");
                s1.Add("06", "java");
                s1.Add("05", "oracle");
                ListBox1.DataValueField = "key";
                ListBox1.DataTextField = "value";
                ListBox1.DataSource = s1;
                ListBox1.DataBind();
            }
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            string c = string.Empty;
            for (int i = 0; i < ListBox1.Items.Count; i++)
                if (ListBox1.Items[i].Selected)
                    c += ListBox1.Items[i].Text + "<br/>" + ListBox1.Items[i].Value;

            Label1.Text = "Name:" + TextBox1.Text + "<br/> Selected Courses<br/>" + c;
        }

ASPX：

ASPX:

<form id="form1" runat="server">
    <asp:ListBox SelectionMode="Multiple" ID="ListBox1" runat="server"></asp:ListBox>
    <br />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:Button ID="Button1" Text="Submit" runat="server" OnClick="Button1_Click" />
    <br />
    <asp:Label ID="Label1" runat="server"></asp:Label>
    </form>
