## Add(VectorLayer, bool) {#add_8}

Creates a [`VectorMapLayer`](../../vectormaplayer/) with default symbolizer and adds it to the map. Layers are rendered in addition order.

```csharp
public void Add(VectorLayer layer, bool keepOpen = false)
```

| Parameter | Type | Description |
| --- | --- | --- |
| layer | VectorLayer | A vector layer to represent by [`VectorMapLayer`](../../vectormaplayer/). |
| keepOpen | Boolean | `true` to leave the vector layer open after the [`Map`](../) object is disposed; `false` to dispose the layer. |

### Exceptions

| exception | condition |
| --- | --- |
| ArgumentNullException | Layer is `null`. |
