错误1 运算符“*”无法应用于“int”和“方法组”类型的操作数

[madenameduo]

protected void Page_Load(object sender, EventArgs e)
{
ArrayList shopCartList = (ArrayList)Session["shopList"];
GridView1.DataSource = shopCartList;
GridView1.DataBind();
// GridView1.DataKeyNames = new String[] { "isbn" };

//计算购物车物品总价格
int sumPrice = 0;
for (int i = 0; i < shopCartList.Count; i++)
sumPrice += (((shopObject)shopCartList[i]).Cpdj * ((shopObject)shopCartList[i]).Count);
labSumPrice.Text = "购物车总价格为：" + sumPrice + "元";
}


出错在这一行
sumPrice += (((shopObject)shopCartList[i]).Cpdj * ((shopObject)shopCartList[i]).Count);

sumPrice += ((shopObject)shopCartList[i]).Cpdj * ((shopObject)shopCartList[i]).Count;

是Count()吧

这样不是更清晰点？ int sumPrice = 0; for (int i = 0; i < shopCartList.Count; i++) { shopObject shop=(shopObject)shopCartList[i]; sumPrice += (shop.Cpdj * shop.Count); }

引用 1 楼 bdmh 的回复:

sumPrice += ((shopObject)shopCartList[i]).Cpdj * ((shopObject)shopCartList[i]).Count;

这个和原来的语句不是一模一样么？

不是啊。。。我改了还是错误错误 1 “shopObject”不包含“Count”的定义，并且找不到可接受类型为“shopObject”的第一个参数的扩展方法“Count”(是否缺少 using 指令或程序集引用?)

改后还是一个同样的错误，这下怎么办 不知所措啊

看下这个 shopObject model类的Cpdj , Count属性 很明显是这两个属性类型有一个不是int,估计是 Cpdj的问题吧 产品点击?产品定价?

[z22708387]

sumPrice += ((shopObject)shopCartList[i]).Cpdj * ((shopObject)shopCartList[i]).Count;
