ArcGIS.Core.Data Namespace / Feature Class / GetShape Method
Example

In This Topic
    GetShape Method (Feature)
    In This Topic
    Gets the geometry of this feature. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public Geometry GetShape()
    Public Function GetShape() As Geometry

    Return Value

    The geometry of this feature.
    Exceptions
    ExceptionDescription
    This feature's type of shape (i.e., geometry) is not supported.
    A geodatabase-related exception has occurred.
    Example
    Retrieve Geometry from Geodatabase
