Examples
The following code example shows how to access the ContextToken property. This code example is adapted from the Conversations SDK sample, from the SupplierWorkflow.Designer.cs file.
ReceiveActivity receiveQuoteFromShipper3;
receiveQuoteFromShipper3 = new System.Workflow.Activities.ReceiveActivity();
System.Workflow.Activities.ContextToken contexttoken1 = new System.Workflow.Activities.ContextToken();
contexttoken1.Name = "Shipper3Context";
receiveQuoteFromShipper3.ContextToken = contexttoken1;
Remarks
Each ContextToken is defined within the scope of an owner activity. Users can model two distinct context tokens with the same name but different owner scopes. The value of the contexts associated with these context tokens are different at runtime.
By default, each workflow has an implicit root context token, scoped at the root activity level. The name of the root context token is '(RootContext)' and the OwnerActivityName is null. If a ReceiveActivity activity does not have a ContextToken associated with it, the root context token is used.
