【问题描述】：
在这里，我开发了代码，当用户单击“购买”按钮时，将使用该数据打开新视图。现在数据是在文本框中获取的，因为我想插入相同的数据，但是 ProductName 被完美地插入，但是每次产品的价格都为零，即使在文本框中，实际价格也是可见的，但也存在错误 我想用实际数据插入 ProductName 和 Price 下面的代码是：
型号
public class Purchase
{
[Key]
public int purID { get; set; }
public string productName { get; set; }
public int productPrice { get; set; }
public string customerEmail { get; set; }
}
