FeatureSet

 

	The FeatureSet class has a lot of power collected within it, but for getting started, this breakdown itemizes some of the most straight forward elements.  Like Raster and ImageData, FeatureSet inherits from the DataSet class, and so gains some common characteristics related to geographic Extent and Reprojection.
	Indicates whether the DataTable is filled with attributes.
	Indicates whether M or Z values exist.
	A standard System.Data.DataTable loaded with the attributes for the features.
	The Geographic Extent of the data.
	The list of vector and attribute pairings.  Accessing this will set IndexMode to false.
	Point, Line or Polygon.
	The string filename.  Ends in .shp for shapefiles.
	True if only the vertex array is loaded and the Features list is not created yet.
	Copies the column names and types from other tables or FeatureSets.
	Forces the attributes to be loaded into memory.
	Call this to update the vertex array after changing Feature coordinates.
	Opens a new file.  Shapefiles should opened using the *.shp file.
	Reprojects the vertices in memory to a new coordinate system.
	Saves the in memory content to a different file.
	Uses a geographic extent to select only the features in that extent.
	Uses a string Where expression as a filter to return matching features.
	Geographic selection that returns the feature index instead of the features.
	Refreshes any cached extents after features have been changed.
