How to retrieve data fields

In this example, the console application connects to a K2 server loops through a worklist. It then writes data fields to the console. XML fields and process instance data could also be accessed while the worklist item is open.

In the following example, provide values for the variables that begin with the underscore (_) character to match your environment and scenario. If pasting this code into a console application, set values for the variables and paste the code into a class called from the Main function.

References to SourceCode.HostClientAPI and SourceCode.Workflow.Client are also required.
