参数

<表达式> An expression that returns a value. The value from the expression is then compared against the values of each case until a match is found. This expression is always evaluted exactly once each time through the structure.
<值> To <值> The case is executed if the expression is between the two values.
<值> The case is executed if the expression matches the value.

注意/说明

If no cases match the Switch value, then the Case Else section, if present, is executed. If no cases match and Case Else is not defined, then none of the code inside the Switch structure, other than the condition, will be executed.

Switch 语句允许嵌套使用.Switch 语句对字符运算是大小写敏感的.
