You can use scope inner and outer for transaction:

string connectionString = ConfigurationManager.ConnectionStrings["db"].ConnectionString;
var option = new TransactionOptions
{
     IsolationLevel = IsolationLevel.ReadCommitted,
     Timeout = TimeSpan.FromSeconds(60)
};
using (var scopeOuter = new TransactionScope(TransactionScopeOption.Required, option))
{
    using (var conn = new SqlConnection(connectionString))
    {
        using (SqlCommand cmd = conn.CreateCommand())
        {
            cmd.CommandText="INSERT INTO Data(Code, FirstName)VALUES('A-100','Mr.A')";
            cmd.Connection.Open();
            cmd.ExecuteNonQuery();
        }
    }
    using (var scopeInner = new TransactionScope(TransactionScopeOption.Required, option))
    {
        using (var conn = new SqlConnection(connectionString))
        {
            using (SqlCommand cmd = conn.CreateCommand())
            {
                cmd.CommandText="INSERT INTO Data(Code, FirstName) VALUES('B-100','Mr.B')";
                cmd.Connection.Open();
                cmd.ExecuteNonQuery();
            }
        }
        scopeInner.Complete();
    }
    scopeOuter.Complete();
}
