該例項的功能是通過 Label控制元件顯示資料庫連線是否成功。

using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class WebSite1_Ex05_02 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Write("<center><b>使用Label控制元件顯示資料庫連線是否成功</b></center>");
        string connString = "server=localhost;uid=sa;pwd=80712;database=Northwind";
        try
        {
            SqlConnection myConnection = new SqlConnection(connString);
            myConnection.Open();
            Label1.Text = "連線成功，連線字串是：" + connString;
        }
        catch
        {
            Label1.Text = "連線失敗，連線字串是：" + connString;
        }
    }
}
