如何删除 <string, list<Items>> 字典的项目

Question

我有一本水果字典<string, list<Fruit>>我的字典给出以下输出

Job ID: 1001         items:
                        "Apple"
                        "Mango"
                        "Banana"
                        "Pine Apple"
                        "Orange"

Job ID: 1002         items:
                        "Banana"
                        "Mango"
                        "Pine Apple"
                        "Orange"
                        "Apple"

Job ID: 1003         items:
                        "Apple"
                        "Banana"
                        "Orange"
                        "Pine Apple"
                        "Mango"

现在我想从水果列表中删除一个特定的水果

例如，我想从列表

中删除Apple

foreach(var i in fruitDic)
            {
                foreach(var k in i.Value)
                {
                    // furitName is variable which I want to remove from list
                    if (k.Name == fruitName)
                    {
                        // here I am getting an error
                        k.Value.Remove(fruitName);

                    }
                }
            }

我收到一条错误消息：Error CS1503 Argument 1: cannot convert from 'string' to 'Practice.Models.Fruit'

Answer 1

你可以使用 RemoveAll

Removes all the elements that match the conditions defined by the specified predicate.

给定

var dict = new Dictionary<string, List<Fruit>>();

用法

foreach (var list in dict.Values)
   list.RemoveAll(x => x.Name == "SomeFunkyFruit");
