try
        {
            string myConnection = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
            SqlConnection con = new SqlConnection(myConnection);
            con.Open();
            string myExecuteQuery = "backup database Database to  disk='d:\backuptext.dat'";
            
            SqlCommand myCommand = new SqlCommand(myExecuteQuery,con);
         
            myCommand.ExecuteNonQuery();
            con.Close();
            Label1.Text = "备份成功";
        }
        catch { Label1.Text = "备份失败"; }


老是备份失败，帮我看看指明下那里错了……
