C#中this的用法

 

namespace WindowsFormsApplication3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            // Create objects:
            Employee E1 = new Employee("XiaoLong", "Brown"); //创建了一个E1对象
            // Display results:
            E1.Salary = 30.00m; //虽然已经存在了Salary，在此将E1对象的Salary属性重新赋一次值
            E1.printEmployee();
        }
    }
    class Employee
    {
        private string name;
        private string alias;
        private decimal salary;
        // Constructor:
        public Employee(string name, string alias)
        {
            this.name = name;
            this.alias = alias;
        }
        // Printing method:
        public void printEmployee()
        {
          MessageBox.Show("Name:" + name + "\r\n" + "Alias : " + alias + "\r\n" + "Taxes:" + Employee.CalcTax(this));
         // Passing the object to the CalcTax method by using this:
        }
        public decimal Salary
        {
            get
            {
                return salary ;
            }
            set
            {
                salary = value;
            }
        }
        public static decimal CalcTax(Employee E)
        {
            return 0.08m * E.Salary;
        }
    }

}

可以更好的理解，printEmployee中的this表示为类的当前对象，也就是E1对象。

运行结果为：
