用一句Linq把一个集合的属性值根据条件改了，其他值不变

第一次发博。 - -

刚无聊看到群里一位朋友在提问，大晚上没人解答，遂自己默默打开了VS，敲起了代码。

问题：请问怎么将集合newFoods中Name含有"包子"的Number+1，LINQ可以一句话写出来 ?

List<Food> newFoods = new List<Food>{
    new Food { Money = 10, Name = "天津包子", Number=1 },
    new Food { Money = 10, Name = "狗不理包子", Number = 1 },
    new Food { Money = 10, Name = "小笼包子", Number = 1 },
    new Food { Money = 10, Name = "馒头", Number = 1 },
    new Food { Money = 10, Name = "粽子", Number = 1 }
};

我先是敲了一下正常的写法，很快出来了。

但是用Linq一直不知道该怎么写，反而越写越麻烦，还想出准备先筛选出一个对象，再把两个对象合并的傻办法。

后来发现原来select里是可以直接查询完返回原对象的。之前用Linq一直以为只能是 model.Select(o=>o.property==xxx) 这样用，也没去深究，看来是修为不够。

最后的代码：

 1         #region
 2         public class Food
 3         {
 4             public string Name { get; set; }
 5             public int Money { get; set; }
 6             public int Number { get; set; }
 7         }
 8         static void Example1()
 9         {
10             List<Food> newFoods = new List<Food>{
11                new Food { Money = 10, Name = "天津包子", Number=1 },
12                new Food { Money = 10, Name = "狗不理包子", Number = 1 },
13                new Food { Money = 10, Name = "小笼包子", Number = 1 },
14                new Food { Money = 10, Name = "馒头", Number = 1 },
15                new Food { Money = 10, Name = "粽子", Number = 1 }
16             };
17             //Linq写法
18             newFoods = newFoods.Select(o =>
19             {
20                 o.Number = o.Name.Contains("包子") ? o.Number + 1 : o.Number;
21                 return o;
22             }).ToList();
23             //普通写法
24             for (int i = 0; i < newFoods.Count; i++)
25             {
26                 newFoods[i].Number = newFoods[i].Name.Contains("包子") ? newFoods[i].Number + 1 : newFoods[i].Number;
27             }
28             //遍历输出
29             foreach (Food food in newFoods)
30             {
31                 Console.WriteLine("名称：" + food.Name + ",价格：" + food.Money + ",数量：" + food.Number);
32             }
33             Console.ReadLine();
34         }
35         #endregion
