C#新手简单问题,求解释
// keywords_this.cs
// this example
using System;
class Employee
{
private string name;
private string alias;
private decimal salary = 3000.00m;
// Constructor:
public Employee(string name, string alias)
{
// Use this to qualify the fields, name and alias:
this.name = name;
this.alias = alias;
}
// Printing method:
public void printEmployee()
{
Console.WriteLine("Name: {0}\nAlias: {1}", name, alias);
// Passing the object to the CalcTax method by using this:
Console.WriteLine("Taxes: {0:C}", Tax.CalcTax(this));
}
public decimal Salary
{
get { return salary; }
}
}
class Tax
{
public static decimal CalcTax(Employee E) //这里的(Employee E )是什么意思?是实例化还是
//作/参传递,求详细解答
{
return 0.08m * E.Salary;
}
}
class MainClass
{
static void Main()
{
// Create objects:
Employee E1 = new Employee("John M. Trainer", "jtrainer");
// Display results:
E1.printEmployee();
}
}
/*运行结果:Name: John M. Trainer
Alias: jtrainer
Taxes: $240.00
*/
