将类的实例作为ListBox中的一项输出

在类中使用重载函数重写ToString函数

    class Customer
    {
        public string FirstName;
        public string LastName;
        public decimal Blance;
        public override string ToString()
        {
            return this.FirstName + ";" + this.LastName + ";" + this.Blance;
        }
    }

 

 

        private void btnAddCustomer_Click(object sender, EventArgs e)
        {
            Customer c = new Customer();
            c.FirstName = tbFirstName.Text;
            c.LastName = tbLastName.Text;
            c.Blance = decimal.Parse(tbBlance.Text);
            lbListCustomer.Items.Add(c);
           
        }

 

搞定。。。。。。。
