I'm using Visual Web Express and i'm including a c# file named Constants to access the common functionalities.
The C# file is included in App_Code directory and when i access the c# file using the code below it shows the error:
Compiler Error Message: CS0246: The type or namespace name 'Constants' could not be found (are you missing a using directive or an assembly reference )
public partial class _Default : System.Web.UI.Page
Line 20: {
Line 21: Constants cons = new Constants();
Line 22: ArrayList fileContents = new ArrayList();
Line 23: string connString = "";
What is the problem How to use the c# file in App_Code directory

CS0246: The type or namespace name 'Constants' could not be found

You must specify the namespace in your usings or explicit specify it by decleration:
With using keyword
using My.Namespace;
public partial class _Default : System.Web.UI.Page
{
My.Namespace.Constants cons = new My.Namespace.Constants();
ArrayList fileContents = new ArrayList();
}
Specific
public partial class _Default : System.Web.UI.Page
{
My.Namespace.Constants cons = new My.Namespace.Constants();
ArrayList fileContents = new ArrayList();
}

For those who are interested in...
I was encountering exactly the same problem and had to apply an unpleasantly dirty solution to evade that problem.
Following situation:
* IIS-Web called SampleWeb
* APP_CODE contains the file Sample.cs
* Subdirectory inside the root directory called SubDir1 --> this subdirectory is declared as separate "Application" inside the IIS6.0 Settings (you know, the folder icons becomes a gear wheel)
When I create a common WebForm-File, e.g. Test1.aspx inside the root folder of the web site and refer to the .cs-file as
Sample
MySample = new Sample();the pretty Test1.aspx file works like a charm - no error messages, nothing - pure beauty.
And now the funny part of the story:
When I conduct the same procedure (exactly the same way) INSIDE the subdirectory SubDir1 that painful error message
CS0246: The type or namespace name 'Sample' could not be found
I was trying around different approaches (using namespaces, adding assemblies, etc.) , but it didn't work.
The only way I could get rid of that error was to place the file outside the SubDir1 -subdirectory (directly in the root dir).
By the way: I cannot remove the Application-settings off the SubDir1-subdirectory due to uncountably many legacy reasons.
I don't particularly expect a solution for that anomaly, but somehow or other it would be greatly interesting to hear any kind of suggestion.
To all the anguished poor souls called C# developers.

The Visual WebDeveloper Express Edition does not generate any namespace for any file or form.If i use a common namespace called as Transaction and if i put all code inside that for all the files including the c# file inside App_Code and if i use
using Transaction;
namespace
Transaction{
public partial class _Default : System.Web.UI.Page{
Constants cons = new Constants();Then an error showing Transaction not found.
Tell me how to use the namespace for files inside App_Code and those files which are outside App_Code and .aspx files. What is the actual problem which i encounter in Web Express Edition.
Also without any namespace if i run using inbuilt Asp.Net development server it is running.Only in iis if i run using http://localhost/ it is showing the error.
