Performs a conditional if/else evaluation.

[Visual Basic .NET]
Public Function Con ( _
    ByVal ConditionalRaster As IGeoDataset, _
    ByVal TrueRaster As Object, _
    [ByRef FalseRaster As Object] _
) As IGeoDataset

[C#]
public IGeoDataset Con (
    IGeoDataset ConditionalRaster,
    object TrueRaster,
    ref object FalseRaster
);
[C#]

Optional Values

FalseRaster   To indicate that this parameter is undefined, first define a variable object Missing=Type.Missing; then pass this in as ref Missing. 
[C++]
HRESULT Con(
  IGeoDataset* ConditionalRaster,
  LPUNKNOWN TrueRaster,
  VARIANT* FalseRaster,
  IGeoDataset** Con
);

[C++]

Parameters
ConditionalRaster [in]

  ConditionalRaster is a parameter of type IGeoDataset
TrueRaster [in]
  TrueRaster is a parameter of type LPUNKNOWN
FalseRaster [optional]
  FalseRaster is a parameter of type VARIANT

  To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND.
Con [out, retval]
