Server.MapPath specifies the relative or virtual path to map to a physical directory.

  • Server.MapPath(“.”) returns the current physical directory of the file (e.g. aspx) being executed
  • Server.MapPath(“..”) returns the parent directory
  • Server.MapPath(“~”) returns the physical path to the root of the application
  • Server.MapPath(“/”) returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

An example:

Let’s say you pointed a web site application (http://www.example.com/) to the root of your domain

C:\Inetpub\wwwroot

and installed your shop application (as virtual directory in IIS and marked as application) in

D:\WebApps\shop 

If, you call Server.MapPath in following request:

http://www.example.com/shop/product/GetProduct.aspx?id=2342

then,

  • Server.MapPath(“.”) returns D:\WebApps\shop\products
  • Server.MapPath(“..”) returns D:\WebApps\shop
  • Server.MapPath(“~”) returns D:\WebApps\shop
  • Server.MapPath(“/”) returns C:\Inetpub\wwwroot
  • Server.MapPath(“/shop”) returns D:\WebApps\shop

If Path starts with either a forward (/) or backward slash (\), the MapPath method returns a path as if Path were a full, virtual path.

If Path doesn’t start with a slash, the MapPath method returns a path relative to the directory of the request being processed.

Note: In C#, @ is the verbatim literal string operator meaning that the string should be used “as is” and not be processed for escape sequences.

OpenFileDialog.SafeFileName March 10, 2009

I had developed an application in VS2008 with .NET 2.0 . The application was deployed using the VS2008 deployment project  with .NET Framework as pre-req. AutoCAD 2009 was already installed on all the client machines so the pre-req conditions were satisfied so .NET Framework was not skipped during the installation of the application.

Later on,  I made a clean installation of WIN XP SP3 on my development machine. I skipped VS 2008 because I could not find its proper usage. VS2005 was sufficient for me.

Today, I got the a request for some updates in the application. For this purpose, I converted it to VS2005. On building the application is got the error about OpenFileDialog.SafeFileName. It was really a strange thing as the application was working smoothly on all the client machines.

SafeFileName returns only the File Name from the whole path. Although, I got the problem solved by doing some string operations:
String safeName = opdg.FileName.Substring(opdg.FileName.LastIndexOf("\\") + 1);
// 1 has been added to skip the \

I Googled about it and it was disclosed that this property is available in .NET Framework 2.0 SP1 which is installed along with VS2008.

I noticed some missing menu items in the VS2005 (like clean, rebuild, and many others) but i continued by using the commands from other locations; until I got stucked!  I wanted to export a form as a template but the Export was not available in the File menu.
The details of my environment are:

Since, I installed Resharper for the first time, the first option that came to my mind is that its due to Resharper. I tried to explore different options in the Resharper and VS specially the Key Mapping but no result. I was only left with the option to uninstall Resharper and I did it. But to my surprise, the problem was still there.
In such a situation, I call my rescue agent GooGle. The first suggestion provided by the agent worked well and my problem was solved.
I had installed SQL Server 2005 for the first time (initially, I was using SQL 2000 as per client requirements) but I don’t considered it bcoz it’s a Microsoft product and it was least expected to interfere in the scenario. I was WRONG. This problem occurred due to a bug in it.

Here is the solution provided by Microsoft.

Hope it will also solve your problem if u faced such an issue.
