Dynamically add hyperlink to sharepoint document library subfolder in list

Question

How can I add a link to a list item column that is of type hyperlink. The link should be a link to a subfolder in a document library.

What the program does it creates a new subfolder in a document library and after that I need to update a sharepoint list and create a list item with the details of the newly created document library subfolder, including a hyperlink to the subfolder. The list item field/column where the hyperlink is stored is labeled as File

I am using Microsoft.SharepointOnline.CSOM package with .net framework


Web web = clientContext.Web;
clientContext.Load(web, a => a.ServerRelativeUrl);
clientContext.ExecuteQuery();

// Create the subfolder in Sharepoint Document Library
Folder parentFolder = web.GetFolderByServerRelativeUrl(web.ServerRelativeUrl + "/" + parentFolderPath);
clientContext.Load(parentFolder);
clientContext.ExecuteQuery();

parentFolder.AddSubFolder(newSubFolderName, new ListItemUpdateParameters());
parentFolder.Folders.Add(newSubFolderName);
clientContext.Load(parentFolder);
clientContext.ExecuteQuery();

...

// Create a list item, need to add the hyperlink here in the field I have in my list called "File"
clientContext.Load(web.Lists,
        lists => lists.Include(list => list.Title, 
                               list => list.Id));

clientContext.ExecuteQuery();

List targetList = clientContext.Web.Lists.GetByTitle(listName);
ListItemCreationInformation itemCreateInfo = new ListItemCreationInformation();
ListItem oListItem = targetList.AddItem(itemCreateInfo);

oListItem["File"] = ???

oListItem.Update();
clientContext.ExecuteQuery();

Try this

oListItem["File"] = new FieldUrlValue
{
  Url = "<your folder link here>"
  Description = "My New Folder"
}

Do you face any issues?

-- update: to get the URL to the folder try this:

var newFolder = parentFolder.AddSubFolder(newSubFolderName, new ListItemUpdateParameters());
clientContext.Load(newFolder);
clientContext.ExecuteQuery();

.....

oListItem["File"] = new FieldUrlValue
{
  Url = newFolder.ServerRelativeUrl
  Description = "My New Folder"
}

The problem I have is that I dont know how to get the "<your folder link here>" value. I need the link to the new subfolder after I create it

Ah, I see. I have updated the answer

parentFolder.AddSubFolder returns void. I tried parentFolder.Folders.Add(subFulderName) and that returns it. However when I try to assign it to Url like oListItem["File"] = new FieldUrlValue, I get an Invalid Request error.

I had to convert the url to proper Uri format. It works now. Ty
