无法获取提交到SQL Server的数据

我一直在网上寻找答案，但还没有找到。

我有一个小的控制台应用程序，我试图插入一些数据到SQL Server数据库(.mdf数据库文件)，一切运行没有错误，但是当我在服务器资源管理器中打开DB后，数据不存在。

这是代码:

using (TransactionScope scope = new TransactionScope())
{
    using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["FrameBudgetDB"].ToString()))
    {
        SqlCommand cmd = new SqlCommand();
        cmd.Connection = conn;
        conn.Open();
        cmd.CommandText = string.Format("SELECT TOP 1 category_id FROM businesses WHERE '{0}' LIKE CONCAT('%',description,'%')", transDescription.Replace("'", "''"));
        SqlDataReader reader = cmd.ExecuteReader();
        try
        {
            if (reader.HasRows)
            {
                while (reader.Read())
                {
                    categoryId = (int)reader[0];
                }
            }
            else
            {
                categoryId = 44; // Unknown
            }
        }
        finally
        {
            reader.Close();
        }
        // Get Transaction Type
        int transTypeId = 0;
        cmd.CommandText = string.Format("SELECT trans_type_id FROM transaction_types WHERE description = '{0}'", transType);
        reader = cmd.ExecuteReader();
        try
        {
            if (reader.HasRows)
            {
                while (reader.Read())
                {
                    transTypeId = (int)reader[0];
                }
            }
        }
        finally
        {
            reader.Close();
        }
        SqlTransaction trans = conn.BeginTransaction("InsertTransactiolns");
        try
        {
            cmd.Transaction = trans;
            cmd.CommandText = string.Format(
                                "BEGIN " +
                                        "IF NOT EXISTS(SELECT * FROM transactions " +
                                                                     "WHERE transaction_date = '{0}' " +
                                                                     "AND description = '{1}' " +
                                                                     "AND trans_type_id = {2} " +
                                                                     "AND amount = {3} " +
                                                                     "AND(category_id = {5} OR previous_category_id = {5} )) " +
                                     "BEGIN " +
                                             "INSERT INTO transactions(transaction_date, description, trans_type_id, import_date, category_id, amount) " +
                                             "VALUES('{0}', '{1}', {2}, '{4}', {5}, {3}) " +
                                     "END " +
                                "END", transDate, transDescription.Replace("'", "''"), transTypeId, amount, DateTime.Now, categoryId);
            rowsInserted = rowsInserted + cmd.ExecuteNonQuery();
            trans.Commit();
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
            try
            {
                trans.Rollback();
            }
            catch (Exception e2)
            {
                Console.WriteLine(e2.Message);
            }
        }                                        
    }
}

数据库连接字符串为:

<connectionStrings>
    <add name="FrameBudgetDB" 
         connectionString="Data Source=(LocalDB)'MSSQLLocalDB;AttachDbFilename=|DataDirectory|FrameBudget.mdf;Integrated Security=True;Connect Timeout=30" 
         providerName="System.Data.SqlClient" />
</connectionStrings>

，数据目录为:

AppDomain.CurrentDomain.SetData("DataDirectory", Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + @"'FrameBudget'"));
