The following table summarizes the problems that can occur as a result of setting the most commonly used transaction isolation levels:

The following code segment shows how the isolation level can be set with the TransactionScope class. With the constructor of TransactionScope, you can set the TransactionScopeOption that was discussed earlier and the TransactionOptions. The TransactionOptions class allows you to define the IsolationLevel and the Timeout.

var options = new TransactionOptions { IsolationLevel = IsolationLevel.ReadUncommitted, Timeout = TimeSpan.FromSeconds(90) }; using (var scope = new TransactionScope( TransactionScopeOption.Required, options)) { // Read data without waiting for locks from other transactions, // dirty reads are possible. }
