PreparingEnlistment.ForceRollback Method

Indicates that the transaction should be rolled back.

Namespace:  System.Transactions
Assembly:  System.Transactions (in System.Transactions.dll)

public void ForceRollback()

An implementation of the Prepare method of the IEnlistmentNotification interface calls this method to indicate that the transaction must be rolled back.

		class myEnlistmentClass : IEnlistmentNotification
		{
			public void Prepare(PreparingEnlistment preparingEnlistment)
			{
				Console.WriteLine("Prepare notification received");

				//Perform transactional work 

				//If work finished correctly, reply prepared
				preparingEnlistment.Prepared();

				// otherwise, do a ForceRollback
				preparingEnlistment.ForceRollback();
			}

			public void Commit(Enlistment enlistment)
			{
				Console.WriteLine("Commit notification received");

				//Do any work necessary when commit notification is received 

				//Declare done on the enlistment
				enlistment.Done();
			}

			public void Rollback(Enlistment enlistment)
			{
				Console.WriteLine("Rollback notification received");

				//Do any work necessary when rollback notification is received 

				//Declare done on the enlistment
				enlistment.Done();
			}

			public void InDoubt(Enlistment enlistment)
			{
				Console.WriteLine("In doubt notification received");

				//Do any work necessary when indout notification is received 
				
				//Declare done on the enlistment
				enlistment.Done();
			}
		}
		class myEnlistmentClass : IEnlistmentNotification
		{
			public void Prepare(PreparingEnlistment preparingEnlistment)
			{
				Console.WriteLine("Prepare notification received");

				//Perform transactional work 

				//If work finished correctly, reply prepared
				preparingEnlistment.Prepared();

				// otherwise, do a ForceRollback
				preparingEnlistment.ForceRollback();
			}

			public void Commit(Enlistment enlistment)
			{
				Console.WriteLine("Commit notification received");

				//Do any work necessary when commit notification is received 

				//Declare done on the enlistment
				enlistment.Done();
			}

			public void Rollback(Enlistment enlistment)
			{
				Console.WriteLine("Rollback notification received");

				//Do any work necessary when rollback notification is received 

				//Declare done on the enlistment
				enlistment.Done();
			}

			public void InDoubt(Enlistment enlistment)
			{
				Console.WriteLine("In doubt notification received");

				//Do any work necessary when indout notification is received 
				
				//Declare done on the enlistment
				enlistment.Done();
			}
		}
