Newbie Namespace Question

[Guest]

Hi,

The following code snippet doesn’t compile with,

helloworld.cs(25,39): error CS0246: The type or namespace name 'Library' could not be found (are you missing a using directive or an assembly reference?)

Why can’t the “Library†namespace be found when its location “Company.Application†has been referenced in the Tester class.

using System;

namespace Company.Application.Library
{
class Math
{
public static int Add(int a, int b)
{
return(a + b);
}
}
}

namespace Test
{
using Company.Application;

class Tester
{
static void Main()
{
int iResult = Library.Math.Add(2, 2);
Console.WriteLine(iResult);
}
}
}

The following code snippet doesn?t compile with,

helloworld.cs(25,39): error CS0246: The type or namespace name
'Library' could not be found (are you missing a using directive or an
assembly reference?)

Why can?t the ?Library? namespace be found when its location
?Company.Application? has been referenced in the Tester class.

Namespaces aren't hierarchical as far as the compiler (or framework) is
concerned.
