Delete SharePoint Online site programmatically

Question

I'm attempting to delete a Site collection but receiving this error:

Microsoft.SharePoint.Client.ServerException: 'Cannot delete top-level site: https://{tenant}.sharepoint.com/teams/6KG9A4SO.'

    public static void DeleteSite(NetworkCredential nc, string siteToDelete)
    {
        using (var cc = new ClientContext(siteToDelete))
        {
            cc.Credentials = new SharePointOnlineCredentials(nc.UserName, nc.SecurePassword);

            // Delete the web object  
            cc.Web.DeleteObject();
            // Execute the query to the server.  
            cc.ExecuteQuery();
        }

    }

What am I doing wrong?

Delete SharePoint Site collections programmatically using CSOM with PowerShell on SharePoint online / office 365.

function DeleteSiteCollection(){  
try{  
    $tenant = New-Object Microsoft.Online.SharePoint.TenantAdministration.Tenant($ctx)  
    $removeSite = $tenant.RemoveSite("https://abc.sharepoint.com/sites/CustomTest")  
    $ctx.Load($removeSite)          
    $ctx.ExecuteQuery()  

    Write-Host "Site Collection has been deleted"        
    Write-Host "----------------------------"  
}  
catch{  
     write-host "$($_.Exception.Message)" -foregroundcolor red  
}   
} 

Note: The above set of operations needs to be called to get it executed.

You are trying to delete the root web of your site collection.

You should attempt to delete the entire site collection, you can do this via PowerShell remove-sposite by connection to the https://tenant-admin.SharePoint.com
