Question

I am using the method

File.SaveBinaryDirect 

in Microsoft.SharePoint.Client to insert new documents in a Sharepoint Library. just wondering what is the most effective way of getting the Guids of those new records.

Answer 1

Well, you’ve just saved the file to a particular URL – get the File by that URL, and then use the ListItemAllFields property to get the ListItem that would contain those IDs

From here:

var FileSrvRelUrl = "/sub/doclib/Folder/File.doc";
using (var fileStream = new MemoryStream(new byte[100]))
{
    Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, FileSrvRelUrl, fileStream, false);
}
var web = clientContext.Web;
var f = web.GetFileByServerRelativeUrl(FileSrvRelUrl);
var item = f.ListItemAllFields;
item["SomeField"] = "Value";

item.Update();
clientContext.Load(item, i=>i.Id);
clientContext.ExecuteQuery();
