Getting ID of uploaded document or File in SharePoint 2010

If you are uploading a File‚Äč to SharePoint 2010 programmatically and wanted to get the ID of that newly created file then you can use following code.

//Upload your File

SPFile myFile = spList.RootFolder.Files.Add
                (FileUpload1.PostedFile.FileName, StreamImage, replaceExistingFiles);

SPListItem item = imgFile.Item;

// Then you can use item.ID

I am not providing full code for file upload but the key here is to get SPListItem from SPFile class.

I hope it helps.
