2 XX XX 2 8.00 16.00
跪求类似这样的单据功能实现
[解决办法]
给你写一个demo，你可以自己去修改。
首先，定义好数据实体模型，例如
public class Product
{
public string Name { get; set; }
public decimal Price { get; set; }
private DateTime _最后更新时间 = DateTime.Now;
public DateTime 最后更新时间
{
get { return _最后更新时间; }
set { _最后更新时间 = value; }
}
}
public class ProductOrder
{
public string ProductName { get; set; }
public DateTime DateTime { get; set; }
public string Address { get; set; }
public int Quantiy { get; set; }
public string Supplier { get; set; }
}
using System;
using System.Collections.Generic;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
public static class BLL
{
private static List<Product> ProductDatabase = new List<Product>(){
new Product { Name="月亮美眉", Price=9009999},
new Product{ Name="屋子", Price=83722323},
new Product{ Name="一本书", Price=20}
};
public static IEnumerable<Product> GetProducts()
{
return ProductDatabase;
}
private static List<ProductOrder> ProductOrderDatabase = new List<ProductOrder>
{
new ProductOrder{ ProductName="月亮美眉", DateTime= DateTime.Now, Address="公主坟1号", Quantiy=100},
new ProductOrder{ ProductName="月亮美眉", DateTime= DateTime.Now.AddSeconds(12312), Address="公主坟2号", Quantiy=200, Supplier="天上人间"}
};
public static IEnumerable<ProductOrder> GetOrders(string productName)
{
return from x in ProductOrderDatabase
where x.ProductName == productName
select x;
}
