The comparison geometry.
Example

In This Topic
Disjoint Method (GeometryEngine)
In This Topic
Returns true if geometry1 and geometry2 are disjoint.
Syntax
```public bool Disjoint(
Geometry geometry1,
Geometry geometry2
)```
```Public Function Disjoint( _
ByVal geometry1 As Geometry, _
ByVal geometry2 As Geometry _
) As Boolean```

#### Parameters

geometry1
The base geometry.
geometry2
The comparison geometry.

#### Return Value

True if geometry1 and geometry2 are disjoint.
Exceptions
ExceptionDescription
Either geometry1 or geometry2 or both are null.
The method is not implemented for GeometryBag.
Incompatible spatial references between the input geometries.
Remarks
Two geometries are disjoint if they don't have any points in common. Equivalent to not Intersects.

Example
Determine if two Geometries are disjoint

// pt on pt
//

MapPoint pt = MapPointBuilderEx.CreateMapPoint(1.0, 1.0);

disjoint = GeometryEngine.Instance.Disjoint(multiPoint, pt);     // result is false
