Launch Browser and pass parameters.

[C# Programming]

I have windows app and am using c#. I want to launch default browser from c# program and pass some parameters. Basically what i have is content type (eg. "application/msword") and byte array of content (word/excel/pdf docs in byte array). I want to pass these two parameters to browser and let it open the doc. Can anybody please guide me to achieve this? One more thing i don't want to create any file in local disk.

Thanks.
