以下是我的代码.

public class PItem
{
    public String content;
    public int count;
    public int fee;
    public int amount;
    public string description;

    // Default values
    public PItem(String _content = "", int _count = 0, int _fee = 0, string _description = "", int _amount = 0)
    {
        content = _content;
        count = _count < 0 ? 0 : _count;
        fee = _fee;
        description = _description;
        amount = _amount < 0 ? 0 : _amount;
    }
}

这是在课堂上.当我尝试运行程序时,它会出现此错误:

不允许使用默认参数说明符

我该如何解决这个错误？
