Initializes a new instance of the Filter class. Use the properties to specify the search criteria.

Namespace: ESRI.ArcGISExplorer.Data
Assembly: ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.900 (2.0.0.900)

Syntax

C#
public Filter()

Visual Basic (Declaration)
Public Sub New

Examples

The code below create creates a Filter object using the default constructor, sets Geometry, SpatialSearchType, and SpatialColumnName properties then executes the query using the Table.Search method.

CopyC#

//Open ArcSDE geodatabase
Geodatabase gdb   = new Geodatabase(@"C:\Data\SQLServer.sde");

//Open FirePerimeters feature class 
Table fires = gdb.OpenTable("sde.DBO.FirePerimeters");

//Open Properties feature class
Table properties = gdb.OpenTable("sde.DBO.Properties");

//Get a fire polygon by its unique ID
Geometry firePoly = fires.GetRow(14).Geometry;

//Create the search criteria to find all properties affected by this fire
Filter searchCriteria = new Filter();
searchCriteria.Geometry = firePoly;
searchCriteria.SpatialSearchType = FilterSearchOptions.Intersects;
searchCriteria.SpatialColumnName = properties.Columns.SpatialColumnName;

//Execute the query
RowCollection rows = properties.Search(searchCriteria);

CopyVB.NET
