Returns a collection of Raster objects which represents all the supported raster files in a directory.

Namespace:  ESRI.ArcGISExplorer.Data

Assembly:  ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.1500 (2.0.0.1500)

Syntax

C#
public ReadOnlyCollection<Raster> GetRasters()
Visual Basic (Declaration)
Public Function GetRasters As ReadOnlyCollection(Of Raster)

Return Value

A ReadOnlyCollection object consisting of Raster objects each of which represents a file-based raster consisting of a rectangular grid of cells arranged into rows and columns.

Examples

The code below explores the contents of a directory. Example 3 illustrates how to iterate over a collection of all rasters in the specified directory.
CopyC#
//The "C:\Data" directory contains the following:
//mountains shapefile
//mtn_ratings dBase file
//northgorms.jpg
//southgorms.jpg

//Create a DataDirectory object for the specified file path
DataDirectory dir = new DataDirectory(@"C:\Data");

//Example 1 - print out the names of all dBase files and shapefiles
foreach (Table table in dir.GetTables())
{
  System.Diagnostics.Debug.Print(table.Name);
}
//Output prints:
// mountains
// mtn_ratings

//Example 2 - print out the names of all shapefiles
foreach (Table shapefile in dir.GetTables(TableDiscoveryOptions.Spatial))
{
  System.Diagnostics.Debug.Print(shapefile.Name);
}
//Output prints:
// mountains

//Example 3 - print out the names of all raster files
foreach (Raster raster in dir.GetRasters())
{
  System.Diagnostics.Debug.Print(raster.Name);
}
//Output prints:
// northgorms.jpg
// southgorms.jpg
