Create folder if not exists about megaapiclient HOT 11 CLOSED

Well Mega API allows to create nodes with same name. We can change CreateFolder method to throw if we try to create a folder with a name that already exist but it's a shame to introduce this kind of limitation.
I think it's client side responsibility to get the folder node or create it if it doesn't exist.

Another solution is to add a method GetOrCreateFolder but if there is already 2 folders with the same name, the method is unable to choose and will throw.

What do you think?

Hi! I think it is very ambiguous to have 2 or more folders/files with the same name GetOrCreateFolder will be fine for me but not for others
You can give me some steps to implement that:create folder if it not exists or else to select the folder

another question : do I need to distribute Newtonsoft.Json.dll ?

thanks!

I don't know VB but something like that should work:

Dim myFolder As INode = client.nodes.[FirstOrDefault](Function(n) n.Type = NodeType.Folder And n.Name = "Upload")
If myFolder = Nothing then
    myFolder = client.CreateFolder("Upload", root)
End If

About Newtonsoft.Json.dll, you must distribute it with MegaApiClient

good,it works with some little corrections:
Dim myFolder As INode = nodes.[FirstOrDefault](Function(n) n.Type = NodeType.Directory And n.Name = "upload") If myFolder Is Nothing Then myFolder = client.CreateFolder("upload", root) End If

thanks!

Any solution for C# on this?

from megaapiclient.

To create a folder on root if it doesn't exist:

var nodes = client.GetNodes(); // Retrieve all folders and files
var root = nodes.Single(n => n.Type == NodeType.Root); // Retrieve root node

// Search a folder with "folder" name under root
var myFolder = client.GetNodes(root).FirstOrDefault(n => n.Type == NodeType.Folder && n.Name == "folder");

// Create the "folder" if not found
if (myFolder == null)
{
  myFolder = client.CreateFolder("folder", root);
}

I think you should make it a Boolean parameter to the CreateFolder() function.

I prefer to avoid having this kind of flag because I don't want to have to download all the nodes for this check in the CreateFolder() method. MegaApiClient is "stateless" in the sense it doesn't keep a cache of the nodes and cannot make any assumption about the existing nodes structure.
I think it's the library consumer task to refresh/maintain the nodes cache and decide based on its content if a folder needs to be created or not.
