小编Mar*_*ius的帖子

我正在使用C#构建的Windows窗体应用程序出现问题.该错误表明"foreach语句不能对'CarBootSale.CarBootSaleList'类型的变量进行操作,因为'CarBootSale.CarBootSaleList'不包含'GetEnumerator'的公共定义".

我似乎无法理解造成这种情况的原因.

这是抛出错误的代码:

        List<CarBootSaleList> Sortcarboot = new List<CarBootSaleList>();

        foreach (CarBootSale c in carBootSaleList)
        {
            if (c.Charity == "N/A")
            {
                Sortcarboot.Add(carBootSaleList);
                textReportGenerator.GenerateAllReport(Sortcarboot, AppData.CHARITY);
            }
        }

这是CarBootSaleList类,它说没有GetEnumerator定义:

public class CarBootSaleList
{

    private List<CarBootSale> carbootsales;

    public CarBootSaleList()
    {
        carbootsales = new List<CarBootSale>();
    }

    public bool AddCarBootSale(CarBootSale carbootsale)
    {
        bool success = true;
        foreach (CarBootSale cbs in carbootsales)
        {
            if (cbs.ID == carbootsale.ID)
            {
                success = false;
            }
        }
        if (success)
        {
            carbootsales.Add(carbootsale);
        }
        return success;
    }

    public void DeleteCarBootSale(CarBootSale carbootsale)
    {
        carbootsales.Remove(carbootsale);
    } …

当我们点击更新按钮时，我需要得到

日期、客户名称、小时数、费率、表格日期、截止日期、增值税、服务税、总金额详情..

使用“Jquery”

请帮助我....

我非常感谢你......
