Question Passing IEnumerator as a parameter with parameters

Probably a very basic knowledge is required to do this but it seems all my years of programming did not teach me this particular case. Here's a code snippet with the part that I've added to demonstrate what I need which obviously gives an error if I use it:

Code (CSharp):

1. public IEnumerator GetItemTable(string url, IEnumerator onFinishedCallback)
2.         {
3.             UnityWebRequest unityWebRequest = UnityWebRequest.Post(url, "");
4.             yield return unityWebRequest.SendWebRequest();
5.             if (String.IsNullOrEmpty(unityWebRequest.error))
6.             {
7.                 if (onFinishedCallback!= null)
8.                     StartCoroutine(onFinishedCallback(unityWebRequest.downloadHandler.text));
9. //THIS IS WHAT I'M TRYING TO DO BUT OBVIOUSLY GIVES ERROR
10.             }
11.             else
12.             {
13.                 Debug.Log("Error getting items list")
14.                 //other stuff
15.             }
16.         }

So is there a way for me to add parameters to onFinishedCallback?

 

To make your code works you need to change IEnumerator to Func<string, IEnumerator>

But in my opinion, it's cleaner to change IEnumerator to Action<string> and do not start coroutine in GetItemTable. Let caller decide what to do in the callback. If caller needs a coroutine that's caller responsibility to start it.

 

Good point actually. Thanks a lot for the tip. Seems I've never used Func<> syntax before
