How to get UserId of current user in Custom Workflows of Microsoft Dynamics CRM 2011?

Question

I need userId of current user in Custom Workflows of Microsoft Dynamics CRM 2011. So can you suggest me how to get it?

Answer 1

Assuming that you are using c#, and that you created your custom workflow following Create a Custom Workflow Activity article from MSDN, it should inherit CodeActivity class, and has a method like:

protected override void Execute(CodeActivityContext context)
{
  // Your code here
}

To get the current userId, you need to obtain the IWorkflowContext from the CodeActivityContext, like this:

IWorkflowContext workflowContext = context.GetExtension<IWorkflowContext>();

And then:

var id = workflowContext.UserId;
