You should reference System Web and call     HttpContext Current Server MapPath

By calling it   var path   System Web HttpContext Current Server MapPath  default aspx      Make sure you add a reference to the System Web assembly

User · Answer

Architecturally  System web should not be referred in Business Logic Layer  BLL   Employ BLL into the solution structure to follow the separate of concern principle so refer System Web is a bad practice  BLL should not load run in Asp net context  Because of the reason you should consider using of System AppDomain CurrentDomain BaseDirectory instead of System Web HttpContext Current Server MapPath

Maybe you could abstract this as a dependency and create an IVirtualPathResolver  This way your service classes wouldn t be bound to System Web and you could create another implementation if you wanted to reuse your logic in a different UI technology
