c#添加事物（全部执行和带保存点的执行）

全部执行

 protected void Button2_Click(object sender, EventArgs e)

        {

            // 执行事务

            SqlConnection con = new SqlConnection(str);

            con.Open();

            SqlTransaction tran = con.BeginTransaction();



            try

            {

                SqlCommand cmd1 = new SqlCommand("INSERT INTO Code( name ) VALUES ( 'ww1')", con);

                SqlCommand cmd2 = new SqlCommand("INSERT INTO Code( name ) VALUES ( 'ww2')", con);

                cmd1.Transaction = tran;

                cmd2.Transaction = tran;

                cmd1.ExecuteNonQuery();

                cmd2.ExecuteNonQuery();

                tran.Commit();

            }

            catch

            {

                tran.Rollback();

            }

            finally

            {

                con.Close();

                GetData();

            }

        }

执行带保存点的事务

 protected void Button3_Click(object sender, EventArgs e)

        {

            // 执行带保存点的事务

            // 执行事务

            SqlConnection con = new SqlConnection(str);

            con.Open();

            SqlTransaction tran = null;

            tran = con.BeginTransaction();

            try

            {

                SqlCommand cmd1 = new SqlCommand("INSERT INTO Code( name ) VALUES ( 'ww3')", con);

                SqlCommand cmd2 = new SqlCommand("INSERT INTO Code( name ) VALUES ( 'ww4')", con);

                cmd1.Transaction = tran;

                cmd1.ExecuteNonQuery();

                tran.Save("One");

                cmd2.Transaction = tran;

                cmd2.ExecuteNonQuery();

                tran.Rollback("One");

                tran.Commit();

            }

            catch

            {

                tran.Rollback();



            }

            finally {

                con.Close();

                GetData();

            }

        }
