當兩個字典值都包含像“字典”這樣的列表時，在兩個字典之間進行驗證和比較<string, List<string> &gt;&quot;

Question

嗨，兩個通用詞典如下語法格式

Dictionary<string, List<string>> Test1 = new Dictionary<string, List<string>>(); Dictionary<string, List<string>> Test2 = new Dictionary<string, List<string>>();

現在我需要比較和驗證這兩個字典

樣本數據會像

示例 1

測試1

細繩	列表
一個	蘋果、香蕉
乙	葡萄、梨
C	橙子、櫻桃

測試2

細繩	列表
一個	蘋果、香蕉、西瓜
乙	葡萄、梨
C	橙子、櫻桃

這個上面的例子應該被驗證並發現 test1 不包含在 Test2

示例 2

測試3

細繩	列表
一個	蘋果、香蕉
乙	葡萄、梨
C	橙子、櫻桃

測試4

細繩	列表
一個	蘋果、香蕉
乙	葡萄、梨
C	橙子、櫻桃
D	芒果、菠蘿、李子

應該驗證上面的這個例子，並發現 test3 包含在 Test4 中

Answer 1

請注意，如果List<>中的字符串順序不重要，請考慮使用HashSet<>而不是List<> 。 下面的代碼做我認為你想要的......

static bool List1IsSubsetOfList2(List<string> list1, List<string> list2)
{
  return !list1.Except(list2).Any();
}

static bool List1ContentsSameAsList2(List<string> list1, List<string> list2)
{
  // if order is relevant do not sort
  list1.Sort();
  list2.Sort();
  // same entry values in same order
  return list1.SequenceEqual(list2);
}

static bool Dictionary1SubsetDictionary2(Dictionary<string, List<string>> dict1, Dictionary<string, List<string>> dict2)
{
  var k1 = dict1.Keys.ToList();
  var k2 = dict2.Keys.ToList();
  var fKeys = List1IsSubsetOfList2(k1, k2);
  return fKeys && k1.All(k => List1ContentsSameAsList2(dict1[k], dict2[k]));
}

var test1 = new Dictionary<string, List<string>>
{
   { "A", new List<string> { "Apple", "Banana" } }
  ,{ "B", new List<string> { "Grape", "Pears" } }
  ,{ "C", new List<string> { "Orange", "Cherry" } }
};
var test2 = new Dictionary<string, List<string>>
{
   { "A", new List<string> { "Apple", "Banana", "Watermelon" } }
  ,{ "B", new List<string> { "Grape", "Pears" } }
  ,{ "C", new List<string> { "Orange", "Cherry" } }
};
var test3 = test1;
var test4 = new Dictionary<string, List<string>>
{
   { "A", new List<string> { "Apple", "Banana" } }
  ,{ "B", new List<string> { "Grape", "Pears" } }
  ,{ "C", new List<string> { "Orange", "Cherry" } }
  ,{ "D", new List<string> { "Mango", "Pineapple", "Plum" } }
};

Console.WriteLine($"Test1 is contained in Test2 {Dictionary1SubsetDictionary2(test1,test2)}");
Console.WriteLine($"Test2 is contained in Test1 {Dictionary1SubsetDictionary2(test2,test1)}");
Console.WriteLine($"Test3 is contained in Test4 {Dictionary1SubsetDictionary2(test3,test4)}");
Console.WriteLine($"Test4 is contained in Test3 {Dictionary1SubsetDictionary2(test4,test3)}");

結果

Test1 is contained in Test2 False
Test2 is contained in Test1 False
Test3 is contained in Test4 True
Test4 is contained in Test3 False
