c#的事务

创建一个应用台控件程序

static void Main(string[] args)
        {
            using (SqlConnection sqlcon = new SqlConnection(@"server=192.168.3.11;database=model;uid=sa;pwd="))
            {
                sqlcon.Open();
                SqlTransaction  objtran;
                objtran = sqlcon.BeginTransaction("Method");
                SqlCommand objcmd = new SqlCommand();
                objcmd.Connection = sqlcon;
                objcmd.Transaction = objtran;                
                try
                {
                    objcmd.CommandText = "insert into Stu (id,name) values(1,'33')";                    
                    object a = objcmd.ExecuteScalar();                    
                    objcmd.CommandText = "insert into Stu (id,name) values(2,'66')";                    
                    a = objcmd.ExecuteScalar();  
                    objcmd.ExecuteScalar(); 
                    Console.WriteLine(a.ToString());                   
                    objtran.Commit();

                }
                catch(Exception ex)
                {
                    objtran.Rollback();
                    Console.WriteLine(ex.Message);
                    Console.ReadLine();
                }
            }
            Console.ReadLine();
        }
