比较两个字典 c# 并获得相同的键

Question

我有两本词典。一个是实际的字典（键的词和值的定义），另一个是 Word 文件中的词，存储在第二本词典中。

//first dictionary
    var xdoc = XDocument.Load("dicoFrancais.xml");
            var dico = xdoc.Root.Elements()
                               .ToDictionary(a => (string)a.Attribute("nom"),
                                             a => (string)a.Element("DEFINITION"));

//second dictionary
Dictionary<string, string> motRap = new Dictionary<string, string>();
        Microsoft.Office.Interop.Word.Application application = new Microsoft.Office.Interop.Word.Application();
        Document document = application.Documents.Open("monfichiertxt.docx");


        int count = document.Words.Count;
        for (int i = 1; i <= count; i++)
        {                
            string text = document.Words[i].Text;                
            motRap.Add(text, "blabla");                
        }
        // Close word.
        application.Quit();

而且我想比较两个字典的键并获得与第一个字典的值相同的键，这样我就可以拥有具有该键和值的第三个字典。我试过这个： var intersectMembers = dico.Keys.Intersect(motRap.Keys) .ToDictionary(t => t, t => dico[t]); 但它不起作用。有谁可以帮助我吗，谢谢你。（抱歉我的英文不是很好）

Answer 1

I want to compare the keys of the two dictionaries and get the same keys with the values of the first dictionary.

var thirdDictionary = dico
  .Where(keyValue => motRap.Keys.Contains(keyValue.Key))
  .ToDictionary(keyValue => keyValue.Key, keyValue => keyValue.Value);
