sql - How to set isolation level on SqlCommand/SqlConnection initialized with no transaction

Question

The following method is supposed to peroform a dirty read on an open connection. There are no transactions. Where do I set IsolationLevel?

public string DoDirtyRead(string storedProcName, SqlConnection connection)
{
    using (SqlCommand command = new SqlCommand(storedProcName, connection))
    {
        command.CommandType = CommandType.StoredProcedure;
        // HOW TO SET IsolationLevel to READ_UNCOMMITTED here?
        command.ExecuteNonQuery();
    }
}

Answer 1

If you don't want to do transactions, you can set it once when you open the connection and it will remain at that setting until you change it. So just do:

connection.BeginTransaction(IsolationLevel.ReadUncommitted).Commit();

Probably not the best for your specific case, since you are opening the connection, using it, and throwing it away, but I wanted to put this answer in for anyone with a longer-lived connection.
