Returns a string indicating the name and identifier of this CoordinateSystem.

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

Syntax

C#
public override string ToString()

Visual Basic (Declaration)
Public Overrides Function ToString As String

Return Value

A string indicating the name and identifier of this CoordinateSystem.

Remarks

ToString will return the name and identifier of the CoordinateSystem, and is suitable for use in debugging to quickly check the type of coordinate system which is being represented. The Name and Id of the CoordinateSystem can also be returned separately by using the Name and Id properties.

The string returned by this method is different to the string returned by ExportToPrjString()()().

Examples

The code below shows how you can identify any layers in the current MapDisplay with a CoordinateSystem that is different to that of the MapDisplay. A list of all Layers is created, showing which use the same CoordinateSystem as the MapDisplay, and which use a different CoordinateSystem (and are therefore reprojected automatically when drawn), and creates a list of these layers. The code assumes you have imported the Geometry and Mapping namespaces.

CopyC#

// Identify the CoordinateSystem of the current DisplayMode using the shortcut property.
ESRI.ArcGISExplorer.Mapping.MapDisplay disp = ESRI.ArcGISExplorer.Application.Application.ActiveMapDisplay;
CoordinateSystem dispCS = disp.CurrentCoordinateSystem;

// Iterate all Layers in the Map.
StringBuilder sameCs = new StringBuilder(Environment.NewLine);
StringBuilder diffCs = new StringBuilder(Environment.NewLine);
System.Collections.ObjectModel.ReadOnlyCollection<Layer> layers = disp.Map.GetMapItems<Layer>();
foreach (Layer lyr in layers)
{
  // Show information about the CoordinateSystem using the overloaded ToString method.
  string info = lyr.Name + ": " + lyr.CoordinateSystem.ToString();
  // Compare the systems using the Id property.
  if (lyr.CoordinateSystem.Id == dispCS.Id)
    sameCs.AppendLine(info);
  else
    diffCs.AppendLine(info);
}

// Show the results.
MessageBox.Show("Layers which are automatically reprojected: " + diffCs.ToString() + Environment.NewLine +
  "Layers which do not require reprojecting: " + sameCs.ToString(), "Layer Coordinate Systems");
