ContextUtil Class

Obtains information about the COM+ object context. This class cannot be inherited.

Namespace: System.EnterpriseServices
Assembly: System.EnterpriseServices (in system.enterpriseservices.dll)

public sealed class ContextUtil
public final class ContextUtil
public final class ContextUtil
Not applicable.

ContextUtil is the preferred class to use for obtaining COM+ context information. Because the members of this class are all static (shared in Visual Basic), it is not necessary to instantiate it before using them.

The following code example demonstrates how to use ContextUtil to create a transactional ServicedComponent.

[Transaction]
public class TransactionalComponent : ServicedComponent
{

    public void TransactionalMethod (string data)
    {

      ContextUtil.DeactivateOnReturn = true;
      ContextUtil.MyTransactionVote = TransactionVote.Abort;

      // Do work with data. Return if any errors occur.

      // Vote to commit. If any errors occur, this code will not execute.
      ContextUtil.MyTransactionVote = TransactionVote.Commit;

    }

}

/** @attribute Transaction()
 */
public class TransactionalComponent extends ServicedComponent
{
    public void TransactionalMethod(String data)
    {
        ContextUtil.set_DeactivateOnReturn(true);
        ContextUtil.set_MyTransactionVote(TransactionVote.Abort);

        // Do work with data. Return if any errors occur.
        // Vote to commit. If any errors occur, this code will not execute.
        ContextUtil.set_MyTransactionVote(TransactionVote.Commit);
    } //TransactionalMethod 
} //TransactionalComponent
