更新 ConcurrentDictionary<string, Tuple<string

Question

基于ConcurrentDictionary<string, Tuple<string, string>>，我需要更新 Tuple.item1 字符串以删除空格。到目前为止我所尝试的：ConcurrentDictionary<string, Tuple<string, string>> myDictionary = new <string, Tuple<string, string>>RemoveSpacesFromDic(myDictionary);public Boolean ShouldRemoveSpace(string myValue){   return myValue.Contains(" ");}public void RemoveSpacesFromDic(ConcurrentDictionary<string, Tuple<string, string>> sampleDictionary){   List<string> keys = new List<string>(sampleDictionary.Keys);   foreach (string key in keys)   {      if (ShouldRemoveSpace(sampleDictionary[key].Item1))      {         string newValue= sampleDictionary[key].Item1;         //Remove spaces from newValue logic         sampleDictionary[key] = new Tuple<string, string>(newValue, sampleDictionary[key].Item2);      }    }}如果没有键列表逻辑，是否有一种优雅的方法可以做到这一点？也许用 LINQ。

以下是使用 LINQ 的方法：

yourDic.ToDictionary(x => x.Key,                    
                     x => Tuple.Create(x.Value.Item1.Replace(" ", ""), x.Value.Item2));
