Recursive function in foreach

Question

I have to call a function recursively using foreach something like this

 

public JsonResult GetPath(string node)

{

try

{

var project_id = "abc";

String fName = "";

String fID = "";

foreach (string items in GetFolders(project_id, node))

{

for (int j = 0; j < items.Length; j++)

{

if (items.Length == 100000)

{

break;

}

else

{

var Totalitems = items.Split('~');

folderID = Totalitems[0].ToString();

FolderName += Totalitems[1].ToString()+",";

}

}

GetPath(items);

}

}

catch(Exception)

{

}

return Json("", JsonRequestBehavior.AllowGet);

}

 

In this method this GetFolders will return and array

 

Problem is i cant declare string array in foreach
