Sameer,

Whilst I agree that the help for this Class is missing basic examples on how to implement the tool and is something that ESRI should rectify, a simple search on this forum for "RasterCalculator" will find you enough code examples to work out how to use it.

Duncan,

I have done quite research before posting it here. while i don't think you can find 'enough' codes just by searching "RasterCalculator".
I do not want to use RasterMapAlgebraOp and RasterModel is my basic criteria. when i search as you suggested then 99pc of the code are done by using RasterMapAlgebraOp / RasterModel.

let me know if you can help!

Finally did it! posting so that this might be helpful for someone like me. and someone may find it by searching "RasterCalculator" as you suggested...

Public Sub ExecuteRasterCalc()
        Dim expression As String = "'D:\Clip2.img'*'D:\Clip3.img'"
        Dim outputpath As String = "C:\Default.gdb\rastercalc7"
        Dim geoprocessor = New ESRI.ArcGIS.Geoprocessor.Geoprocessor()
        Dim ToolRasterCalc As New ESRI.ArcGIS.SpatialAnalystTools.RasterCalculator(expression, outputpath)
        geoprocessor.OverwriteOutput = True
        geoprocessor.AddOutputsToMap = True
        Dim result As IGeoProcessorResult = geoprocessor.Execute(ToolRasterCalc, Nothing)
    End Sub
