Simplify if else using LINQ

Hi,

I have code like this

private List<NetworkPlanNodesModel> GetNodes(int resourceId)
        {
            var nodes = new List<NetworkPlanNodesModel>();
            var group = String.Empty;
            foreach (var resource in this.resourceNodes)
            {
                if (resource.Id == resourceId)
                {
                    group = NetworkPlanModel.ResourceGroup;
                }
                else
                {
                    group = NetworkPlanModel.FilterResourceGroup;
                }  
             }
             return nodes;
        }

Instead using if else, would it be possible that I am using any LINQ Operator?

Thanks :)
