Hi, guys,
I am using Visual Web Developer Express 2005 for my web application.
I wrote a simple class called MyTestClass.cs and put it in the App_Code
folder.
I compiled it to library from the DOS console using the command line
compiler csc and got a new file called MyTestClass.dll in App_Code.
Now, in the code-behind file Default.aspx.cs for Default.aspx, when I
try to define an object of MyTestClass, the IDE even shows
"MyTestClas s" as an option in the live code-completion drop-down list.
This suggests that MyTestClass.dll has been properly recognized,
doesn't it?
But, when I test my web application, I still get this error message:
Compiler Error Message: CS0246: The type or namespace name
'MyTestClass' could not be found (are you missing a using directive or
an assembly reference?)
Line 9: using System.Web.UI.W ebControls.WebP arts;
Line 10: using System.Web.UI.H tmlControls;
Line 11: using MyTestClass;
Line 12:
Line 13:
If I comment out Line 11, I will get the same error message at line
where I define the MyTestClass object. It looks like that just because
the IDE recognizes a type or namespace doesn't mean the compiler knows
about it, right?
Mind I asking what is wrong? I know nothing about assembly yet. Will
assembly come to the rescue?
Thanks.

If you compile MyTestClass.cs manually from the command-line,
place MyTestClass.dll in the /bin directory and remove MyTestClass.cs
from the App_Code folder.

MyTestClass.cs and have put MyTestClass.dll into bin.
re:

The using directive at the beginning of a code-behind file enables you to use
unqualified class names to reference the DLL methods at compile time:
Class.Method(pa ram1, param2);
Otherwise, you have to use the fully qualified name:
Namespace.Class .Method(param1, param2);
If your class doesn't have a namespace...add one to it.
Then, you can import the namespace with the "using" directive.

It was hectic the last 2 days, and I did not have a chance to test it
out.
Now, I just tried giving it a namespace called MyTestNamespace , then
compiled using csc at the DOS console and put the dll to the bin
folder, removed the .cs source code.
The IDE can still recognize this newly-defined namespace, but the
compiler makes the same complaint.
I did the same thing before, and it worked right in the App_Code
folder. In other words, I did not have to create a bin folder and put
the dll in it.
