当现有资源包含了使用运算式而非简单整数定义符号值的符号定义时，您也可以使用包含的符号档。
You can also use included symbol files when you have existing resources with symbol definitions that use expressions rather than simple integers to define the symbol value.
由于无法保证规则运算式产生器一定会产生唯一的值，所以您不能使用它来填满具有唯一条件约束的使用者定义型别资料行。
Because the Regular Expression generator is not guaranteed to produce unique values, you cannot use it to fill a user-defined type column that has a unique constraint.
运算式可以计算值然后显示结果、成为搜寻条件的一部分或结合资料行内容。
Expressions can calculate values to display, be part of search conditions, or combine the contents of data columns.
利用运算式值中所指定的位元数来将变数值进行向右移位，保持正负号不变，然后将结果指派给变数。
Right shifts the value of a variable by the number of bits specified in the value of an expression, maintains the sign, and assigns the result to the variable.
若要修正此错误，请使用一个新的实值型别变数来储存中继运算式，然后指派值给这个新变数。
To fix this, use a new value-type variable to store the intermediate expression, and assign the value to the new variable.
利用运算式值中所指定的位元数将变数值进行向右移位，不须保持正负号，然后将结果指派给变数。
Right shifts the value of a variable by the number of bits specified in the value of an expression, without maintaining sign, and assigns the result to the variable.
运算式会判断资料行中的值是否介于指定的最小值和最大值。
The expression determines whether a value in a column is between specified minimum and maximum values.
在变数值和运算式的值上执行位元AND，然后将结果指派给变数。
Performs a bitwise and on the value of a variable and the value of an expression and assigns the result to the variable.
属性值会如同变数或常数参与运算式的方式参与运算式，或是储存于指派陈述式左边的变数或属性中。
The value of the property participates in the expression just as a variable or constant would, or it is stored in the variable or property on the left side of the assignment statement.
依据运算式的值，有条件的执行一组陈述式。
Conditionally executes a group of statements, depending on the value of an expression.
如果物件包含具有运算式(例如资料系结)的相依性属性，则会复制运算式的目前值，而不是运算式本身。
If the object contains dependency properties with expressions (such as a data binding), the current value of the expression is copied but not the expression itself.
资源参考会建立内部运算式，该运算式会以执行阶段延后为基础提供指定的属性值。
The resource reference creates an internal expression that supplies the value of the specified property on a run-time deferred basis.
传回布林值，指出运算式是否可以评估为数字。
Returns a Boolean value indicating whether an expression can be evaluated as a number.
在变数值和运算式的值上执行位元OR，然后将结果指派给变数。
Performs a bitwise or on the value of a variable and the value of an expression and assigns the result to the variable.
传回指定乘幂值的基底运算式值。
Returns the value of a base expression taken to a specified power.
