请帮我解决这个问题.为什么在声明  VISUAL BASIC的整数变量时，可以使用  integer.parse但不能在声明字符串变量时使用string.parse .我被告知它不是字符串成员 所以我可能知道字符串成员

从未为String类定义解析方法，可能是因为它没有多大意义.对于整数，它确认可以从字符串创建有效的整数.对于一个字符串，它已经是一个字符串，因此 什么都没创建.

A parse method has never been defined for the String class, probably because it doesn't make much sense.   For an integer, it confirms that a valid integer can be created from the string.  For a string it's already a string, so there is nothing to be created.

 您希望字符串解析方法做什么?您始终可以将自己的parse方法创建为扩展方法，也可以将String类作为子类来创建自己的版本.

 What would you expect a string parse method to do?   You can always create your own parse method as an extension method, or you can subclass the String class to create you own version.
