The following line works fine

SPList list = web.Lists["docLibName"];

The following line raises exception "value does not fall within the expected range"

SPFolder = web.Folders["docLibName"];

You can't get the folder of your list with only this name. you must pass the server relative URL.

To get the folder (rootfolder) of your list you can try :

SPList list = web.Lists["docLibName"];
SPFolder listFolder = list.RootFolder;
  • already tried this, worked but raise another exception when uploading a file to this folder, I always use web.folders and upload to it normally

SPList is SharePoint Object of List types.

So this will worked for you

SPList list = web.Lists["docLibName"];

For getting folder you should use

SPFolder folder = list.GetFolder("Folder Name"); 

Let me know if you need some more assists.
