如何使用 Comparer 初始化嵌套的排序字典?
How to initialize a nested Sorted Dictionary with Comparer?
我想创建一个排序字典的字典,排序字典的键按降序排列。我正在尝试:
private readonly IDictionary<string, SortedDictionary<long, string>> myDict= new Dictionary<string, SortedDictionary<long, string>>();
如何设置比较器:
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,其中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" }
}
}
};
