Is it important to Open a sql connection in the transactionscope

I created a sqlconnection, CN1. Then this CN1 is opened. Later in the code there is a transactionscope. If I execute a sql command on this CN1 connection, is this within transaction?

Code looks like this;

SqlConnection cn1 = new SqlConnection();
cn1.Open(); //connection opened when there is no ambient transaction.
...

using(TransactionScope scope = new TransactionScope())
{
  SqlCommand cmd; //a typical sql command.

  ...

  cmd.ExecuteNonQuery(); //Is this command within transaction?
  ...
}
Solution

  • It is a MUST to open the connection within the TransactionScope to ensure that the connection is enrolled in the transaction.
