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

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.

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;


public __gc class TransactionalComponent : public ServicedComponent {

  void TransactionalMethod (String* data) {

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

    // do work with data

    ContextUtil::MyTransactionVote = TransactionVote::Commit;




Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
