此示例通过在常数表达式中使用 |
| 2. | Type . a constant expression of type
类型的常数表达式可转换为 |
| 3. | A constant can participate in a constant expression , as follows
常数可以参与常数表达式，如下所示： |
| 4. | A constant expression is an expression that can be fully evaluated at compile time
常数表达式是在编译时可被完全计算的表达式。 |
| 5. | A constant expression that overrides the default numerical value of an enumeration member
可选项。重写枚举成员的默认数值的常数表达式。 |
| 6. | Provided the value of the constant expression is within the range of the destination type
，前提是常数表达式的值处于目标类型的范围之内。 |
| 7. | Any constant or constant expression that evaluates to the data type of the parameter
参数，为必选项。任何计算为参数数据类型的常数或常数表达式。 |
| 8. | Constant expressions , whose operands are all simple type constants , are evaluated at compilation time
编译时计算操作数均为简单类型常数的常数表达式。 |
| 9. | In a checked context , a compile - time error occurs if the operation is a constant expression . otherwise , an
在所检查的上下文中，如果该运算是常数表达式，则发生编译时错误。 |
| 10. | Members of the enumeration and are initialized with constant expressions , as shown in the following example
成员，并使用常数表达式对这些值进行初始化，如下面的示例所示： |
