c# - Get File Icon used by Shell

Question

In .Net (C# or VB: don't care), given a file path string, FileInfo struct, or FileSystemInfo struct for a real existing file, how can I determine the icon(s) used by the shell (explorer) for that file?

I'm not currently planning to use this for anything, but I became curious about how to do it when looking at this question and I thought it would be useful to have archived here on SO.

Imports System.Drawing
Module Module1

    Sub Main()    
        Dim filePath As String =  "C:myfile.exe"  
        Dim TheIcon As Icon = IconFromFilePath(filePath)  

        If TheIcon IsNot Nothing Then    
            ''#Save it to disk, or do whatever you want with it.
            Using stream As New System.IO.FileStream("c:myfile.ico", IO.FileMode.CreateNew)
                TheIcon.Save(stream)          
            End Using
        End If
    End Sub

    Public Function IconFromFilePath(filePath As String) As Icon
        Dim result As Icon = Nothing
        Try
            result = Icon.ExtractAssociatedIcon(filePath)
        Catch ''# swallow and return nothing. You could supply a default Icon here as well
        End Try
        Return result
    End Function
End Module
