using System; using System.Data; using System.Data.SqlClient; class Program { static void Main() { using (var connection = new SqlConnection("YourConnectionString")) { connection.Open(); // Use ReadCommitted to prevent dirty reads using (var transaction = connection.BeginTransaction(IsolationLevel.ReadCommitted)) { try { // Sample database operation using (var command = new SqlCommand("SELECT * FROM YourTable", connection, transaction)) { var reader = command.ExecuteReader(); while (reader.Read()) { Console.WriteLine(reader["YourColumn"]); } } // Commit the transaction transaction.Commit(); } catch (Exception ex) { // Rollback if there's an error transaction.Rollback(); Console.WriteLine($"Error: {ex.Message}"); } } } } } 🔍 Highlights:
- Read Uncommitted: Allows dirty reads 🥴
- Read Committed: Prevents dirty reads ✅
- Repeatable Read: Locks data for reading 🔒
- Serializable: Highest level of isolation 🏆
Choose wisely to balance performance and consistency!
