Can you run a SQL query to check the isolation level:
SELECT CASE transaction_isolation_level
WHEN 0 THEN 'Unspecified'
WHEN 1 THEN 'ReadUncomitted'
WHEN 2 THEN 'Readcomitted'
WHEN 3 THEN 'Repeatable'
WHEN 4 THEN 'Serializable'
WHEN 5 THEN 'Snapshot' END AS IsolationLevel
FROM sys.dm_exec_sessions
where session_id = @@SPID
EDIT
Based on the comments below, there's also a way to get the isolation level from the code. This could be something like that:
using (TransactionScope scope = new TransactionScope())
{
using (SqlConnection connection1 = new SqlConnection("Data Source=localhost;Integrated Security=True"))
{
Transaction trans = Transaction.Current;
System.Transactions.IsolationLevel level = trans.IsolationLevel;
}
}
You can get the current transaction by calling Transaction.Current
.
