An <code>enum</code> might be a better option. Not sure about VB syntax, but C# would be:

<pre><code>internal enum BandSizes {
 BandHeight = HourHeight + 20,
 HourHeight = HalfHourHeight + 20,
 HalfHourHeight = LineHeight + PictureHeight + 20,
 PictureHeight = 20,
 LineHeight = StopHeight + 10,
 LineWidth = 50,
 StopHeight = 30,
}
</code></pre>

(NB. if this is an namespace scope, <code>internal</code> is the most restrictive access, but <code>private</code> is possible if a member of a class or structure.)

EDIT: Here's the VB version:

<pre><code>Friend Enum BandSizes
 BandHeight = HourHeight + 20
 HourHeight = HalfHourHeight + 20
 HalfHourHeight = LineHeight + PictureHeight + 20
 PictureHeight = 20
 LineHeight = StopHeight + 10
 LineWidth = 50
 StopHeight = 30
End Enum
</code></pre>

Where <code>Friend</code> is the VB for <code>internal</code> (and the same limitation on <code>Private</code> is only possible for type members).

blocks|key|664738|text|由于它是VB.NET，如果它们是真正的全局常量，并且它们的名称本身就足够了，那么您还可以创建一个模块来保存它们。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|664739|此外，请注意，如果从外部程序集访问这些常量，则这些常量的值可能会发生更改。因此，如果它们是公共的，并放在一个类库中，例如，将它们作为ReadOnly而不是常量可能会更好。|664740|entityMap|0|LINK|mutability|MUTABLE|url|http://en.wikipedia.org/wiki/Visual_Basic_.NET^0|4|6|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

Since it's <a href="http://en.wikipedia.org/wiki/Visual_Basic_.NET" rel="nofollow noreferrer">VB.NET</a>, if they are truly global constants and their name by themselves is enough, you can also create a Module to keep them in.

Also, be aware that if these constants are accessed from external assemblies there can be issues if the values of these constants can ever change. So if these were public and put in a class library for example it might be better to have them as ReadOnly rather than constant.

blocks|key|2292432|text|在我看来，实现此目的的最佳选择是创建一个仅包含共享、静态成员和常量的(私有)类。您不需要创建对象，并且可以随心所欲地控制可访问性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2292433|+++Private+NotInheritable+Class+BandSizes

In my opinion, the best option for this purpose is to create a (private) class with only shared, static members, and constants. You don't need to create an object and you can control accessibility as you want.

<pre><code> Private NotInheritable Class BandSizes
 Public Const BandHeight As Short = HourHeight + 20
 Public Const HourHeight As Short = HalfHourHeight + 20
 Public Const HalfHourHeight As Short = LineHeight + PictureHeight + 20
 Public Const PictureHeight As Short = 20
 Public Const LineHeight As Short = StopHeight + 10
 Public Const LineWidth As Short = 50
 Public Const StopHeight As Short = 30

 Private Sub New()
 End Sub
 End Class
</code></pre>

Note: <code>NotInheritable</code> is needed in the declaration of the class, because it is what the compiler would produce as <a href="http://en.wikipedia.org/wiki/Common_Intermediate_Language" rel="noreferrer">CIL</a> when you use a Module. I prefer a "standard-.NET"-way over the Visual Basic-only stuff. Besides, you have more control over its accessibility and you can make it as innerclass. This is in fact the <a href="http://en.wikipedia.org/wiki/Visual_Basic_.NET" rel="noreferrer">VB.NET</a> counterpart to a <a href="http://msdn.microsoft.com/en-us/library/79b3xss3%28VS.80%29.aspx" rel="noreferrer">C# static class</a>.

blocks|key|1411776|text|我建议你先看看这篇文章，然后决定应该使用"const“还是应该使用"readonly”，而不是使用"const“。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1411777|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Instead of making it "const", I would recommend you to have a look at the article <a href="http://dotnetacademy.blogspot.com/2011/09/constants-in-net.html" rel="nofollow">Constants in .NET</a> and then decide that you should use "const" or you should go with "readonly".

Say I have some constants that depends on one another, and I decided to keep them together in a container instead of keeping it as individual constants in a class.

I thought use a <code>Structure</code> for that scope, but the compiler forces me to declare a private member for that structure.

<pre><code> ' Compile error: at least one private member is needed.
 Private Structure BandSizes 
 Const BandHeight As Short = HourHeight + 20
 Const HourHeight As Short = HalfHourHeight + 20
 Const HalfHourHeight As Short = LineHeight + PictureHeight + 20
 Const PictureHeight As Short = 20
 Const LineHeight As Short = StopHeight + 10
 Const LineWidth As Short = 50
 Const StopHeight As Short = 30
 End Structure
</code></pre>

As I have only a few integer constants, should I create a shared (static) class?

假设我有一些相互依赖的常量，我决定将它们放在一个容器中，而不是将其作为类中的单个常量。我本想为该作用域使用Structure，但编译器强制我为该结构声明一个私有成员。  ' Compile error: at least one private member is needed.  Private Structure ...
