Add document to document library with more fields

Question

My question is regarind adding a new item to document library programmatically.

Basically, when I add an item to document library it goes as follows: In a document library i click add new and i choose one of the templates basically soemthing like is it a work document or excel document. In this first window I just give the path to the file (using browse button) and i click next.

Then i'm redirected to the next dialog, with a lof of fields which i have to fill in and click ok.

My question now, how to do the same programmatically?

I think it will be a bit different ...

Any ideas?

So as @diptarag said there are post of this all over the place, but I guess I can take a crack at giving you what you want.

Add is pretty simple, if you have a valid SPWeb object you can do...

SPFile file = web.Files.Add(<URL to File>,<bytes>,<Overwrite>);
file.Update();

So you build the exact path to where you are placing your file. So if you are placing your file in Share Docs you can do http://yoursite.com/Shared Documents/myfile.txt. There the file will be named myfile.txt and placed in shared docs. So now the file should be returned as a SPFile object from the add call. To set a content type you must get the content type from the web you are on.

SPContentType contentType = web.ContentType[<Content Type Name>];

Then you can set the content type ID of the list item to that content type's ID. You Also need to get the SPItem of the SPFile.

SPListItem item = file.ListItemAllFields;
item["Content Type ID"] = contentType.Id;
item.Update();

Finally to set a metadata field(Column), do this...

item[<Field Name>] = <Value>;
//Set More Fields....
item.Update();

And that is it. Remember the field names must be valid and the content type you use must be on the list you are adding the document to.
