Answer 1

不要if语句，直接执行；
如果执行有错的话程序会自动转到catch语句块里面执行的。
楼主可以在catch语句块里面写return fasle； public bool Execute(string sql) 
        { 
            bool falg = false; 
            SqlConnection con = dllCon.getConnection(); 
            try 
            { 
                con.Open(); 
                SqlCommand sda = new SqlCommand(sql, con); 
                sda.ContainerExecuteNonQuery(); 
                { 
                    falg = true; 
                }             } 
            catch (Exception ex) 
            { 
                flag = flase； 
            } 
            finally 
            { 
                con.Close(); 
            } 
            return falg;
