我想创建一个排序字典的字典,其中排序的字典按降序排列键.我想尝试： private readonly IDictionarystring, SortedDictionarylong, string myDict= new Dictionarystring, SortedDictionarylong, string(); 如何设置比较器
private readonly IDictionary<string, SortedDictionary<long, string>> myDict= new Dictionary<string, SortedDictionary<long, string>>();
如何设置比较器如：
Comparer<long>.Create((x, y) => y.CompareTo(x))
对于嵌套字典？
使用此代码：var myDict = new Dictionary<string, SortedDictionary<long, string>>();
您正在初始化一个空字典,该字典不包含任何嵌套字典.做后者：
var comparer = Comparer<long>.Create((x, y) => y.CompareTo(x));
var myDict = new Dictionary<string, SortedDictionary<long, string>
{
// Add a SortedDictionary to myDict
{ "dict1", new SortedDictionary<long, string>>(comparer)
{
// Add a key-value pair to the SortedDictionary
{ 123, "nestedValue" }
}
}
};
