使用LINQ省略字典值部分的一些条目,并将其投影到一个新的字典中,以维护原始键

var result = original.ToDictionary(
    pair => pair.Key, // Key in result is key in original
    value => pair.Value  // Value in result is query on original value
                 .Where(item => !item.Contains("abc").ToList());

someDictionary.ToDictionary(Function(x) x.key, _ 
            Function(y) y.Value.Where(not y.Value contains("abc").ToList())

var result1 = dictionary1.Select(x => 
     {
          return new KeyValuePair<object, IList<ISomeInterface>>(
                     x.Key, 
                     x.Value.Where(y => y.Contains("abc")).ToList());
     }).ToDictionary(item => item.Key, item => item.Value);
