<clause number="8.7.1" title="Constants" informative="true">
|
|
<paragraph>A constant is a class member that represents a constant value: a value that can be computed at compile-time. Constants are permitted to depend on other constants within the same program, as long as there are no circular dependencies. The rules governing constant expressions are defined in <hyperlink>14.15</hyperlink>. The example <code_example><![CDATA[
|
|
class Constants
|
|
{
|
|
public const int A = 1;
|
|
public const int B = A + 1;
|
|
}
|
|
]]></code_example>shows a class named Constants that has two public constants. </paragraph>
|
|
<paragraph>Even though constants are considered static members, a constant declaration neither requires nor allows the modifier static. Constants can be accessed through the class, as in <code_example><![CDATA[
|
|
using System;
|
|
class Test
|
|
{
|
|
static void Main() {
|
|
Console.WriteLine("{0}, {1}", Constants.A, Constants.B);
|
|
}
|
|
}
|
|
]]></code_example>which prints out the values of Constants.A and Constants.B, respectively. </paragraph>
|
|
</clause>
