How to get a file path

Could anybody please answer a question that is supposed to be simple, but still I cannot figure it out?
I have an asp.net application called MySolution. Its main part is called MyProject. Also, it has a library called Reporting. Among other things, it contains a rpt file. Now, from MyProject I have to call report.Load(RptFilePath). My question is: how can I get the path of the .rpt file stored in the Reporting directory from the MyProject/MyPage.aspx.cs file?


Thank you in advance,
Dmitriy
