Sample code to check if a Folder exists else create it (SharePoint Online / PnP Framework / C#)

Sharing the sample code that we can use for checking if a particular folder exists and if not then create it in SharePoint Online. It uses PnP Framework and Azure Ad App only permissions.

Here we have used the PnP Framework Library in our console application.

We will be checking for and creating the folder at the below location.

On a successful run, we can see the folder named “MyFolder” created the document library.

Below is the sample code

static void Main(string[] args)
        {
            var siteUrl = "https://w72tk.sharepoint.com/sites/MyTeamSite";          
            var applicationId = "d7eaeeb7-ef0a-474d-9b94-567013576c14";
            var password = "xyz";
            var domain = "w72tk.onmicrosoft.com";
            var certPath = @"C:\SharePointApp\MyTestCertificate.pfx";

            var authManager = new AuthenticationManager(applicationId, certPath, password, domain);
            var foldertoCheck = "MyFolder";
            using (var clientContext = authManager.GetContext(siteUrl))
            {
                var currentWeb = clientContext.Web;
                var folderExists = currentWeb.DoesFolderExists(foldertoCheck);
                if (!folderExists)
                {
                    var list = clientContext.Web.Lists.GetByTitle("Documents");
                    list.RootFolder.Folders.Add(foldertoCheck);
                    clientContext.ExecuteQuery();
                }
            }
        }

Based on entity behavior for SharePoint Folder – Dynamics 365 / Dataverse

After enabling Server-Based SharePoint Integration,

inside Document Management Settings, we can specify folder structure to be based on the entity either Account or Contact.

Here we have opted for Account-based first.

We can see the following folders created on the SharePoint site, that take the table or entity name.

And the records folder for Accounts created with AccountName_GUID format.

And if we open any Contact record >> Files / Documents tab, that will create the account parent folder (if not already created) and the contact folders inside it as shown below.
