我希望使用linq . My Model类MyModel从布尔值为IsActive= true列表中选择ID我希望从IsActive为true列表中选择ID

List<MyModel> ModelEntities = new List<MyModel>();
        MyModel Model = new MyModel();

        Model.IsActive=true;
        Model.ID = 1;
        ModelEntities.Add(Model);

        Model = new MyModel();
        Model.IsActive=true;
        Model.ID = 2;
        ModelEntities.Add(Model);

        
        Model = new MyModel();
        Model.IsActive=true;
        Model.ID = 3;         
        ModelEntities.Add(Model);

    
        Model = new MyModel();
        Model.IsActive=False;
        Model.ID = 4;         
        ModelEntities.Add(Model);

        
        Model = new MyModel();
        Model.IsActive=true;
        Model.ID = 5;         
        ModelEntities.Add(Model);

        
        Model = new MyModel();
        Model.IsActive=False;
        Model.ID = 6;         
        ModelEntities.Add(Model);

        
        Model = new MyModel();
        Model.IsActive=False;
        Model.ID = 7;         
        ModelEntities.Add(Model);

        
        Model = new MyModel();
        Model.IsActive=False;
        Model.ID = 8;         
        ModelEntities.Add(Model);

我想要的结果像{1，2，3，5}。如何才能得到这些ID使用在linq的Where条件。
编辑我只想要其中IsActive = true的ID列表。
