Hi everybody. I think it is quite silly that I ask this question, but, it is really a big problem for me.

I have been trying to write 2 classes declaring namespace.

//Compile using --> csc /target:library myClass.cs
namespace testing{
  public class myClass{
    public string myFunc(){ return "Returned String"; }
  }
}
//End of myClass

//Compile using --> csc testMyClass.cs
using System;
using testing;

public class testMyClass{
  public static void Main(String[] args){
    myClass mc = new myClass();
    Console.Writeline(mc.myFunc());
  }
}
//End of testMyClass

When compile the testMyClass.cs, compiler complains that it couldn't find the namespace 'testing' with the bracket "are you missing a using directive or an assembly reference". Why is that so? Do I need to set any classpath like in Java? If not, how should I solve this problem? Anyone please help....

Hi Nelson,

You'll need to refer the compiler to the DLL you created from your first compilation, by using /r:YourDLLName.dll. So this would work:

csc /r:myClass.dll testMyClass.cs

Don't forget to change Writeline to WriteLine in the second source file.....

Cheers,

Imar
