Parameters

name
Type: System.String
The transaction name.

isSerializing
Type: System.Boolean
Determines the value of transaction.IsSerializing. true indicates that the model is being read from file.

context

Remarks

Use this version if you have written rules and event handlers that use information passed in a transaction context object. Because rules are called in an arbitrary order at the end of a transaction, it is not possible to pass information to or between them directly. The transaction context is a dictionary in which any kind of information can be passed.

Examples

// In a rule:
UsefulInfo info = this.Store.TransactionManager.CurrentTransaction
    .TopLevelTransaction.Context.ContextInfo["akey"] as UsefulInfo;
