About the acquisition of physical path and virtual path in asp.net __net

Request.currentexecutionfilepath; The virtual path for the current request is this format:/virtual directory name/admin/index.aspx
Request.applicationpath//Gets the virtual application root path of the ASP.net application on the server. /virtual directory name (application name)

These are the file paths in the virtual directory, which is the path in IIS. To get the real physical path is to be added on the basis of the above path:
Server.MapPath (Request.applicationpath + "splconfig/classmap.xml")//This may have a bug

It's better that way.
String M_applicationpath=request.applicationpath;
if (this.m_applicationpath== "")
This.m_applicationpath= "/";
if (!this.m_applicationpath.endswith ("/"))
This.m_applicationpath + = "/"; Let's judge for a moment.
Server.MapPath (m_applicationpath+ "Splconfig/classmap.xml")
