Type or Namespace Error

问题

I have two references in my application. In the BAL code i am able to use the namespace "using TestDAL;"

But I am not being able to use the namespace of BAL in my .cs page. This is the error i get,

CS0246: The type or namespace name 'TestBAL' could not be found (are you missing a using directive or an assembly reference?)

And one thing in my bin folder too I only have the TestDAL.dll file. How do I insert TestBAL.dll file?

Can anyone help me with what can be possible reason?

Thanks in Advance,

Try this:

Then, click browse and add your .dll file:

That should help you, if not please leave some feedback.

You could also try using alias for your namespace like this:

using namespaceAlias = TestBAL;

回答2:

Create object of TestBAL objBAL = new TestBAL(); in your cs page. Check out, This codes gives any error or not.
