Passing Parameters to Workflow from Host Application `

To pass parameter to Workflow.

First we need to create a local variable and property in the workflow class.

private string _message = string.Empty;

public string Message

{

get { return _message; }

set { _message = value; }

}

From our hosting application to pass the value for the parameter,

we need to create a generic Dictionary object which uses String for key and Object as value for the parameter.

Key for parameter should exactly match the public property in the workflow.

Dictionary<String, object> wfParam = new Dictionary<string, object>();

wfParam.Add(“Message”, “My Hello World”);

Now we need to pass this Dictionary object to the workflow using one of the overloaded method for CreateWorkflow

WorkflowInstance instance = workflowRuntime.CreateWorkflow(typeof(HelloWorldWorkflow.Workflow1),wfParam );

Bye…
