Compiling namespaces in c#

abhishek_charlie

Dear friends i have problem in compiling namespaces. i have created a namespace having name Mcdonalds and inside it a class called burger. Then i saved this namespace in a folder in c drive called mcdonalds. ie "c:\mcdonalds\mcdonalds.cs" Now when i compiled this from the console window i get a error that this (mcdonalds.cs) does not contain a main() function. Tell me how to compile it as a namespace doesnot contain main function. When i try to access it(mcdonalds namespace) in a file c:\try.cs i get a message that this namespace does not exist. Try to solve this. Abhishek

1: While I don't know the syntax offhand, I believe you can set compile-order or Dependencie, but generally you'll probably want to stick with multiple compiles until you're comfortable with it. Look up "Response Files" and "Builds" in the docs or online. 2: different folders is fine. You just need to provide the entire path when compiling. 3: You have to use the enitire namespace: mcdonalds.burgerobject rather than just burgerobject if you're not using namespace includes. You must compile with references if you expect the .exe to be able to compile properly if you're using things in the DLL. 4: .exe programs can not expose classes outside themselves in .NET (unlike traditional out-of-process com or "ActiveX Servers"). Hope that helps.

Thanks friend. My prob is solved. actually my namespace contains only classes. here it is. namespace mcdonalds { public class Burger { public void MyBurger() { System.Console.WriteLine("i like Burger .because it is very tasty.Will you eat it?"); } } public class fries { public void MyFries() { System.Console.WriteLine("Check this out. Yo man its delicious"); } } } i have saved this in the folder c:\sangrai\mcdonalds\mcdonalds.cs after that i have compiled it with csc /t:library mcdonalds.cs this makes a file mcdonalds.dll and then i craeted a file naming fries2.cs in the same directory(c:\sangrai\mcdonalds\) with the following contents using System; using mcdonalds; class Fries2 { public static void Main() { Burger piz=new Burger(); piz.MyBurger(); } } then i compiled it with csc fries2.cs /r:mcdonalds.dll and my prob got solved. but i know i want to know that 1. is it necessary for me to cahnge the file (namespace) into a dll and then to use and is it necessary to add /r: while compiling the file fries2.cs. 2. What if store the files mcdonalds and fries2 in differnt folders. 3. cant we use the mcdonalds namespace just like other namespaces like System etc ie without giving anyref while compiling the file fries2.cs. 4. what if mcdonalds is a stand alone program. can u help me ? i know i am taking u for grant but thanks any way. abhishek or u can say charlie

What's in this namespace? Is it only classes to reuse? Or is there a standalone program in it? Not quite enough info here. If it ONLY contains classes (Class Library aka DLL) then you have to compile it with the DLL option... like: csc /target:library Ok, say thank you to chornbe.
