Validation 更正代码。还需要对用户输入进行验证检查

问题说明： 编写一个C#程序，只使用一个包含Main（）方法的类和该类中的许多其他方法来计算委托销售员工的实际工资。 员工在一周内收到总销售额的7%作为佣金。这是工资总额。 从收到的工资总额中扣除以下款项，具体依据如下： •联邦税率为16%。 •退休供款为13%。 •8%的社会保障税。 作为解决方案的一部分： •编写一种向用户显示适当说明的方法。 •只编写一个方法，调用或调用两次，分别获取员工姓名和本周的总销售额。 •编写六种单独的方法来计算以下各项： o总薪酬 o联邦减税 o退休供款扣除 o社会保障扣除额 o本周的总扣减额 o本周的实得工资 •编写一种方法，使用适当的消息显示结果，包括 o员工姓名， o总销售额 o工资总额 o扣除联邦税， o扣除社会保障税， o退休供款， o扣除总额 o实得工资总额

注: 调用每个方法时，只将参数作为变量传递

程序输入 允许用户输入该员工的姓名以及该员工本周的总销售额。您的程序只需处理一名员工。 注: 如果输入不符合要求的语法，程序必须生成相应的错误消息。 程序输出： 最终输出应显示所有计算值、所有定义的常量和员工姓名。 注: 1.输出必须以可读格式显示。 2.使用适当的输入测试代码
