Parameters
- filter
- Type: ESRI.ArcGISExplorer.Data..::.Filter

Examples
The code below provides two examples of searching a Table. The first is an SQL-based query to find all
mountains which are classified as being a Munro in the Type column and the second performs a spatial search
to find all mountains within the Edinburgh region.
CopyC#
//Open the mountains and regions feature classes stored in the Scotland file geodatabase Geodatabase gdb = new Geodatabase(@"C:\Data\Scotland.gdb"); Table mountainsTable = gdb.OpenTable("mountains"); Table regionsTable = gdb.OpenTable("regions"); //Example 1 //Perform a SQL-based, attribute query to find all mountains classified as being Munros RowCollection rows = mountainsTable.Search(new Filter("Type = 'Munro'")); foreach (Row mtn in rows) { //Print the name of each Munro that is stored in the Name column System.Diagnostics.Debug.Print(mtn.Values["Name"].ToString()); } //Example 2 //Perform a spatial query to find all mountains contained within the Edinburgh region //get row for Edinburgh from Regions table Row edinRow = regionsTable.GetRow(5); //perform a spatial search rows = mountainsTable.Search(new Filter(edinRow.Geometry, FilterSearchOptions.Contains)); foreach (Row mtn in rows) { //Print the name of each mountain that is stored in the Name column System.Diagnostics.Debug.Print(mtn.Values["Name"].ToString()); }
