How can i open Windows Media Encoder session properties window in C#.NET?

[Mamatha]

Hi

I am developing small application in C#.NET,In that application when i click
on one button,i want to display Windows Media Encoder Session Properties
window.
I searched in Google,and i got some information from MSDN,

http://msdn.microsoft.com/library/de...pertypages.asp

I done exactly like in C#.NET what he told in Visual basic,but while i
executed code,i got the syntax error.

C#.NET Code:
WMEncoderApp EncoderApp = new WMEncoderApp();

IWMEncoder Encoder = EncoderApp.Encoder;

WMEncOutputPage outputpage= new WMEncOutputPage();

//axMSPropShell1.AddObject Encoder;

//axMSPropShell1.AddPage outputpage;

Error:

axMSPropshell1 denotes a field where a class was expected

Please give me any solution or source code to open session properties window
from C#.NET.

This is a very urgent need for me.

Thanks in advance.
