SPListTemplateType.DocumentLibrary cannot be used to create a library

Question

I want to create a new Document Library using server side code and I try to use SPListTemplateType.DocumentLibrary inside SPWeb.Lists.Add() method but it won't allow me. I have to used

 SPListTemplate listTemplate = web.ListTemplates["Document Library"] 

instead, anyone know the reason for this?

Answer 1

If you take a look at the SPListTemplateType construct, it's an enum

SPListTemplateType enumeration

so when you call SPListTemplateType.DocumentLibrary, what you actually get back is the list type ID, in this example 101.

Whereas in second instance, you get actual SPListTemplate object that you can work with.

You can use SPListTemplateType to create library in the following way:

spWeb.Lists.Add("List Name", "List Discription",SPListTemplateType.PictureLibrary);

I know that you mentioned that it didn't work but could you provide any code samples or exception you are getting, if you are getting any? Until we get some more information, it's all speculation.
