IMap.DeleteLayer Method

Deletes a layer from the map.

[Visual Basic .NET]
Public Sub DeleteLayer ( _
    ByVal Layer As ILayer _
)
[C#]
public void DeleteLayer (
    ILayer Layer
);

HRESULT DeleteLayer(
  ILayer* Layer
);
[C++]

Layer [in]

Layer is a parameter of type ILayer*

Remarks

DeleteLayer will automatically recalculate the Map's extent after the successful deletion of a layer.
Tips:
If a layer is selected in the TOC window (IMxDocument::SelectedLayer), you can pass this to DeleteLayer.
When deleting a layer that references a feature class, like a FeatureLayer, executing IDataLayer2::Disconnect will ensure that references to the feature class are cleared.
