Question

如何将事务与使用c＃的函数一起使用例如我有三个功能

//first function 
save();//------to save data-----
//second function 
saveDetailes(); //-----to save detiales ----------
//third function 
updateStauts(); //--------to update onother table ---------------

我想确保使用TransAction实现或不实现所有这些谢谢

Answer 1

经过多次尝试和搜索，我找到了解决我问题的方法

解决方案 将sqlcommand传递给所有函数并从每个函数返回，因为布尔值已保存完成返回true 如果三个函数返回true 事务以其他方式提交事务回滚谢谢

如果我正确理解它，则需要在多种方法中使用通用的SqlTransaction。这就是我的方法。首先，您必须将所有方法收集到一个通用方法中。然后，将您的SqlConenction和SqlTransaction传递给所有方法，并返回一个布尔标志，以通知您的主方法您的查询是否成功。

using System.Data.SqlClient;

namespace SqlTransationDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            //Do your sql logic here 
            DoSomething();
        }

        private static bool DoSomething()
        {
            try
            {
                using (var connection = new SqlConnection("SqlConnectionString"))
                {
                    connection.Open();

                    //If not commited, transaction is rolled-back as soon as it is disposed 
                    using (var transaction = connection.BeginTransaction())
                    {
                        //Either use a false loop to break or throw an exception. Your choice. 
                        do
                        {
                            if (!Foo1(connection, transaction))
                                break;
                            if (!Foo2(connection, transaction))
                                break;
                            if (!Foo3(connection, transaction))
                                break;

                            //Commit 
                            transaction.Commit();

                            return true;
                        }
                        while (false);
                    }
                }

            }
            catch
            {
                return false;
            }
        }

        private static bool Foo1(SqlConnection Connection, SqlTransaction Transaction)
        {
            try
            {
                using (var command = new SqlCommand())
                {
                    command.Connection = Connection;
                    command.Transaction = Transaction;
                    command.CommandText = "Query1";
                    command.ExecuteNonQuery();
                }

                return true;
            }
            catch
            {
                return false;
            }
        }

        private static bool Foo2(SqlConnection Connection, SqlTransaction Transaction)
        {
            try
            {
                using (var command = new SqlCommand())
                {
                    command.Connection = Connection;
                    command.Transaction = Transaction;
                    command.CommandText = "Query2";
                    command.ExecuteNonQuery();
                }

                return true;
            }
            catch
            {
                return false;
            }
        }

        private static bool Foo3(SqlConnection Connection, SqlTransaction Transaction)
        {
            try
            {
                using (var command = new SqlCommand())
                {
                    command.Connection = Connection;
                    command.Transaction = Transaction;
                    command.CommandText = "Query3";
                    command.ExecuteNonQuery();
                }

                return true;
            }
            catch
            {
                return false;
            }
        }
    }
}
