Use of SPListCollection.Add

Question

Can anybody tell me how to use the SPListCollection.Add(String, String, String, String, Int32, String, String, SPFeatureDefinition, SPListTemplate.QuickLaunchOptions) Method?

• What is the purpose of the featureId parameter?
• What is the purpose of the listInstanceFeatureDefinition parameter?
• Which parameters are optional/required?
• What is the format of the url parameter?

Thanks in advance!

Keep running into that same codeplex link...not very helpful for this particular implementation of the method. After some trial and error, I did get this one working and it did get around the "invalid list template" error when trying to create lists from a custom content type (ie BaseTemplate > 100000). The function takes a SPList definition(ListToCopy) from one SPWeb and copies it to another SPWeb (NewWeb). The only missing link right now is the last parameter, docTemplateType, which I was forced to specify manually (101 - MS Word). Not sure how to get that one from the source list.

public static Guid CopyListDefToAWeb(String SourceWebUrl, SPList ListToCopy, SPWeb NewWeb)
    {
        Guid newListGuid = Guid.Empty;
        if (Convert.ToInt32(ListToCopy.BaseTemplate) < 10000)
        {
            newListGuid = NewWeb.Lists.Add(ListToCopy.Title, ListToCopy.Description, ListToCopy.BaseTemplate);
        }
        else
        {
            String newListUrl = ListToCopy.Title.Replace(" ", String.Empty);
            newListGuid = NewWeb.Lists.Add(ListToCopy.Title, ListToCopy.Description, newListUrl, ListToCopy.TemplateFeatureId.ToString(), Convert.ToInt32(ListToCopy.BaseTemplate), "101");
        }

        return newListGuid;
    }
