C#重写ToString方法实例

直接上代码了。

Demo1：加上价格标签

class Program
{
public decimal price { get; set; }
static void Main(string[] args)
{
Program p = new Program();
p.price = 25;
Console.WriteLine(p.ToString());
Console.ReadKey();
}

public override string ToString()
{
return "$"+price.ToString();
}
}

Demo1：修改时间的输出格式

public DateTime time { get; set; }
static void Main(string[] args)
{
Program p = new Program();

p.time = DateTime.Now;

Console.WriteLine(p.ToString());

Console.ReadKey();
}

public override string ToString()
{
return string.Format("{0}年{1}月{2}日",time.Year,time.Month,time.Day);
}
